Sand Nourishment Trial For The Sunshine Coast

Swellnet Dispatch

Beginning on the 16th November, Sunshine Coast Council (SCC) will trial a sand nourishment program.

Using an ocean-going dredge, the vessel will dredge sand from Spitfire Channel - between the southern end of Bribie Island and the northern end of Moreton - and dump it offshore from Alex Beach. The sand may be released via "bottom placement" or  "rainbowing". The former is when the hull splits and directly releases the sand load into the water offering a more accurate and concentrated dump, while the latter diffuses the sand over a wider area and looks just great in photos.

The dredge will operate continuously 24 hours a day up until the 24th November, weather permitting.

There are reasons for Sunny Coast surfers to rejoice, though they'd better wait to see the results before cheering too loudly.

Rather than drop the sand randomly, engineers at SCC plan to account for surfing amenity and place it where it has the best opportunity to improve surf conditions. From the Council website:

"We have been working hard to trial placement shapes that may improve surf amenity along Maroochydore beach. We have been working with engineers that were a part of the Gold Coast Nourishment campaign for the Commonwealth Games to learn from their placement techniques so that Maroochydore can have the best chance at improved surf amenity."

"We will also work with the University of the Sunshine Coast to analyse the surf before, during and after the placement to see if surf amenity has improved."

The Gold Coast has a long history of sand nourishment programs, including dredge and dump operations. In 2017, Gold Coast City Council (GCCC) ran a five month nourishment program that shifted three million cubic metres of sand from offshore reserves into the nearshore zone. The project resulted in good, if shortlived, banks at many beaches on the Gold Coast.

The reason Sunshine Coast surfers should temper their excitement is because the coming program will shift much less sand. Just 30,000 cubic metres of sand will be dredged and dumped.

The best outcome would be for the sand to be released via bottom placement which has less dispersal, leading to shallower banks and a greater chance of influencing wave shape. At any rate, this is only a trial program tailored to provide evidence that may guide any further nourishment work.

It will be possible to track where the vessel dumps its load on our Alex Beach surf cam.

It was originally planned for last March. But after the flooding of the SEQ region in February, the contracted dredger was needed to do remedial dredging in the Brisbane River. Then there was no weather window available in April, and the next available slot is this month.
But I think your not far off the money, it's more about the possible economic benefit from a more family friendly and clubby carnival suitable sandy beach, than it is about creating banks for surfers.

Dredging *shouldn't* immediately impact spitfire banks Steve cos it's supposedly occurring in the channel. Spitfire banks are located in the large Marine National Park area (= Green Zone) so one would hope that dredging wouldn't be occurring there. Probably just finding a new place to dump the spoil from the 365 day a year channel maintenance the Port Corp undertakes (2 birds, 1 stone argument). Stu - i dont think this dredge could solve the Carties/Mooloolah river issue as it is too big to work so shallow/close to shore.

Further to what Sprout has said, and sorry to state the obvious, but if sand blocking the Mooloolah rivermouth is a problem, why not just dredge that sand and move it to Alex (less than 2km) instead of bringing sand in from spitfire (a lot further than 2km)?
Fingers crossed for some nice sand formations!

I wondered about that also, went looking for answers but apparently it's not a Frequently Asked Question. Thought it'd be the proverbial 'two birds, one stone' solution.

They are, however, taking some sand from the Maroochy River.

Why dump sand at all in front of Alex/Sharks?

Is there erosion occurring there?

It seems a bit arbitrary.

From the SCC website:

"Maroochydore Beach has been subject to significant erosion events and the addition of new sand from an external source will help to restore sand to the beach and protect the area from erosion."

Surfed it a few weeks back and the beach was narrow with rock in the shoreys. First time surfing there so I thought that was natural, but perhaps not.

There's alot of sand gone from alot of the coast at the moment, storm bars, alot sitting high up the dunes too. Steep, thin beach, gutters, etc. Non-stop E swell assault, said it before, shows how dependant we are on S Winter flat spells for good sand.

Why is the Nearshore Beach Nourishment trial happening at Maroochydore Beach?
Studies show that there is a limited supply of sand on the Sunshine Coast. Maroochydore Beach has been subject to significant erosion events and the addition of new sand from an external source in the coastal system, such as the Spitfire Channel, helps restore sand to the beach and protect the area from erosion.

There was a short period of time where the 'rainbow' banks along Mermaid/Miami absolutely pumped with a long period south swell that would have otherwise been straight handers on the normal banks.

Don't think the banks were great on shorter period E swells and S swells never really make it into the Sunny Coast, so I'll be interested to see if this improves surf.

The crew from Save Our Spit met with the Lead Engineer on the project who confirmed that no pre-emptive studies or EIS were attempted on any of the sites dredged between Palmy and Narrowneck - so no baseline to work off in terms of marine life impacted or even what types of sediment they were picking up.

The rainbow dredge was pulling up whatever was lying on the bottom and firing it back into the ocean like a cannon.

I skippered a vessel for some research guys working for the GCCC about 8 years ago. It was a study from the Seaway to Dbah for dredging projects such as the Palmy one.

One part of the job was running underwater ROVS over the all the local inshore reefs/wrecks and inshore sand beds. There were a lot of transects that covered the majority of the reef areas. The inshore sand ROV work was done to look for sea grass mainly but also other 'plant' life. That was done as close to the shoreline as I could get the boat. All this was going to get monitored again after any dredging and replenishment, but I have no idea if that's taken place. Supposed to be a before and after pic sort of thing.

The second part was taking sediment samples that were selected from deeper offshore and from a grid pattern. It was a pain in the arse because I had to anchor the boat about 30 times a day within a few metres of the target spots. It was fascinating work though, especially watching the ROV footage and chatting with the researchers.

Nice one mate, that would have been cool and good to know some work was done - yet the lead engineer we met with told us he had no idea of any baseline or previous studies done - this was in early 2017? We then put that to the Mayor's office and got the usual push-back. We also asked for a report on the after-effects (of course, not provided). The lead engineer was an older bloke from NZ who had worked with this barge before, he surfed, and had completed some academic work on dredging impacts - can't remember his name though - I ended up meeting him in person at Mainy one arvo when it was spraying there and he took me through the process.

Anyway, I'm not a fan of short-term solutions to long-term problems but good to know that maybe after all this time, someone was trying to do the right thing around what was on the bottom there before they put that big vacuum over it. Thanks for filling in some blanks!

The surf banks were wiped out fairly quick but that wasn't the goal of the $14mil. I think as a whole the project did its job in building up sand on the foreshore, primarily for the 2018 games, and generally there hasn't been any major erosion concerns or sand cliffs since it was done, even with major swell events.

Arguably building houses on the beach falls into this category too!

Smorto's picture
Smorto's picture
Smorto Wednesday, 2 Nov 2022 at 2:04pm

Should the same logic therefore apply to houses built in flood prone areas or areas with bushfire risk? Just let them flood or let them burn?

mpeachy's picture
mpeachy's picture
mpeachy Wednesday, 2 Nov 2022 at 2:16pm

The same issue arises. Why are we building there in the first place, and why are taxpayers ultimately footing the bill for these planning decisions?

Appreciate that it's not a straightforward issue, but my understanding is that for example a lot of the northern NSW flooding last year was in areas that were known to be flood prone. People move to the flood zones because it's cheap and they're allowed to under planning laws.

Which is fine until the inevitable happens and it's a multi billion dollar problem.

Not saying it's a clear-cut issue, which is why I said "arguably".

Smorto's picture
Smorto's picture
Smorto Wednesday, 2 Nov 2022 at 3:09pm

Yes but a lot of the northern NSW flood events affected the older/CBD portions of towns that were first settled over 100 years ago (i.e centre of Lismore) so its not lax planning laws as most of these flood prone places wouldn't be approved for residential development now. They're cheap because there's historical problems with the land, not because of recent dodgy approvals.

Lismore is at the confluence of 3 creeks with relatively large hinterland catchments and no dams/levees, meaning that it will always be flood prone without human intervention or engineering solutions, but you can't just tell them "hey that's nature, too bad no flood assistance for you".

The same applies to bushfire prone land and there are exemptions from native vegetation clearing laws that allow you to clear radiation zones around your house and fire breaks along your boundaries, not to mention the government assistance offered to bushfire victims.

Sure, beachfront land is owned by the wealthy, but again it was mostly first settled well before planning laws even existed, let alone laws that deal with natural disasters.

Take a look at Casuarina / Salt in NNSW, its one of the newer beachfront subdivisions and has a substantial vegetation buffer to the beachfront.

Its a complex issue for sure, but you can't target one particular group of people (i.e beachfront land owners) and say "sorry that's nature" but for others be sympathetic.

mpeachy's picture
mpeachy's picture
mpeachy Wednesday, 2 Nov 2022 at 3:29pm

I don't think that's what I did.

If there is ongoing fire / flood / erosion risk, I would argue that the government should be returning all of those places to nature.

Would obviously involve large cost (possibly too large especially with housing shortages), but would save us from having to keep paying billions to bail everyone out when we inevitably lose to nature in the places where it dominates us. The longer you ignore the problem the more expensive it gets to repeatedly bandaid.

Smorto's picture
Smorto's picture
Smorto Wednesday, 2 Nov 2022 at 4:31pm

No problems, agree that's not exactly what you said. It just seems to be the rhetoric that people throw out there with valuable beachfront land owners but not for those affected by other natural processes that receive government assistance.

I also agree in a perfect world no-one should be able to live in those areas, but just like compensating beachfront land owners to buy their land back, it ain't going to be cheap to pack up and move an entire town out of a flood zone and ongoing assistance is probably cheaper.... to short sighted governments anyway.

Would be epic to see some coastal residential land bought back and restore some dune systems, but that's surely a bridge too far considering the costs and lack of direct economic benefit.

Smorto's picture
Smorto Wednesday, 2 Nov 2022 at 5:12pm

Haha I live right near where that photo was takaen in the article. The flooding isn't as bad as the photo suggests and it was just the roadway that flooded and the houses themselves were dry. That's typically how newer estates are designed, in times of massive flood allow for the roads to be flooded but the houses are set above the flood level, that's the theory anyway.

Agree it would be great to see some houses pulled back but as you say probably too far to be realistic, they are typically the wealthiest and most willing to have drawn out and costly legal battles that last for years, so the governments will never take them on.

All the whinging regarding the state of the SC banks for past year or two - could it be the unusually frequent east quadrant swell secondary to La Nina. I used to always feel the sunny coast had sand set ups galore, seemingly more stable than the Gold Coast. I always thought it was because the infrequent bank busting swells, lack of southerly swell that preserved the banks.

They say they will only be 'rainbowing' in the mornings if conditions are ok. Afternoon and night drops will be all bottom dumps.
The intended dredge, TSHD Brisbane, has about half the hopper capacity as the Balder R that worked on the Gold Coast, which had a capacity to carry 6000 cbm of sand. That's nearly the equivalent of 80 fully loaded B double trucks in one go.
So, with bottom dumps and rainbowing being half of what they were on the Goldy the sand will probably settle and disperse even quicker.

Hahahaha. This has nothing to do with "surfing amenity". That's just the spin on it to get the local surfing community on side. Make no mistake, it's all about protecting the built assets along the foreshore. SCC will be happy if it does improve surf amenity, but they won't be fussed if it doesn't.

Checkout SCC's Coastal Adaptation Strategy - Five Year Implementation Plan here:

And yeah, the banks along open beaches up here have been getting progressively worse each of the past two years in particular. Patches of goodness especially on northern side of all the permanent and ephemeral creeks as all the rain has punched out sand into some nice shapes. Crew flocking to these like ants to sugar.

Regarding coffee rock, if you look at aerial images of pre- and post- erosion events (such as via NearMaps) it looks like the dune erosion around coffee rock is actually worse (from what I've seen at least). Given there's pretty decent organic content in it, perhaps Gina can mosey on down from one of her many mansions up at Noosa and rip it all out and sell to a developing nation. Shouldn't take much. I hear she's got a spare $15m free that she can spend on it.

7 March 2017 Lydia's Seasonal Timetable > Swell / Wind / Tide direction fuels waves on alt banks
https://www.seabreeze.com.au/forums/Sailing/General/Mooloolaba-to-Tangal...

The Bar has fastest tides in Moreton Bay so it's dredged wider & deeper for easier access.
Any dredging of large Spitfire channel accelerates neighbouring deeper narrow N/W inshore channel.
N/W Channel (Bribie Island > Caloundra) lies in open ocean & is by default costly & risky to dredge.
Dredging is limited by Seasonal Swell periods...must be essential > straight, deep, narrow then retreat!
Inshore beach break shipping lanes are closest > straightest > longest > narrowest > deepest > fastest.
Dredging amplifies "Nearest Erosion hot spots" accelerated by more hungry, larger shipping fleets.
Noting that Ship swing circles are nearest to beaches & line up perfectly with erosion hot spots.

Crew can thank icandig for dredging up the Moreton Bay Conspiracy Channel.
tbb was holding back quite a bit...but it seems the crew are alert & already to switch channels.

4 things leapt off the page during Bay research...all too wild for the Matrix but each must find a home!

(1). Why does the Project Team boast the hopper can dredge 25m unless it is going that deep.
Q: 2032 Olympic size 15m to 25m dredged channel upgrade. (Was that a loose promo?)
A: Port of Bne is pushing for Nuke Sub Base that requires 20-25m depth as minimum to fully function.
Ask! Should a Sub duck under a Naval Frigate or submerge deep enough to hide from a Kidz Drone?
Either way!Port of Bne needs Olympic Size dredging for Olympic sized ADF / Inland Rail Port Channel.

Port of Bne extended WMD Surf Reserve mined line-up outranks sissy neighbour's GC/Noosa WSRs...
Sunny shoots over the bow & goes straight to the top of the heap...Salute yer guts neighbour!
Fully Nuked Surf Reserve...that'll sort out the crew!

(2) Port of Bne need to secure WMD shipping Channel. (Note Bribie has Military Jetty / Bunkers etc...)
Port don't need Caloundra Clowns & Bribie Boyz snaking their Yank Tanks & WMD Sub Mariners.

Recall GC banned all boating anywhere near Games Venues > Olympic WMD Shipping is #1 Security!
Port of Bne + ADF + Govt may keep that bar inoperable! (Google shows dwindling # 150 boats?)
There is no hurry for Locals to breach Oz #3 Shipping lane heading towards #1 Militarized Olympics.

That right! Mooloolaba SLSC are #1 on Cruise Itinerary & that Beach > Ship shot is # 1 Insta Drool.
C'mon! Even Qldurrz drool at the Sunny honey drippin' off that Picture Perfect Postcard.

swellnet did a recent feature on dredging the Mooloolah River timed for return of cruise season.
Cruises tender this river but do have self regulation to tender the beach if so desired.
The extended sand pad may even excuse any extra distance safety requirement.

tbb is not saying SLSC Jetty or Wharf but a real slick landing pad extending beyond the break to Shore.
One could slip around & inside the designer outta break to push ashore inside this waveless zone.
Crew know this can be arranged & closer inspection may suggest or reveal, this is the desired effect.
Project is flexible in it's design & scale...so, anything goes in a trial.

Wotz most important is that the Cruise ships are not to flood the joint but to model Sunny postcards.
It's worth $millions just to show the World Qld has the Tech to deliver on this...just the once..
To borrow a NSW term > "A World First!" don't matter if it's not...just gotta say it before NSW does!
(Truth!) It's actually a really really old school NSW technique! Shh! They don't even know that!

tbb has noticed that Sunny prefers Designer Cruise Ships not yer standard Hi Rise Covid Crates!
Anna don't care if ya pat a whale or grab a pot'n'parmie...it's all about the Olympic Postcard Drool.

Just saying if the cruise passengers go commando on yer local break...it's just a new Olympic Sport.

(4) Studies & even counts are underway to check on Bay Dugongs / Turtles.
La Nina has flooded record Silt over Sea grass.
Dams are flooding record Silt over Sea grass
Dredging flooding record Silt over Sea grass
So why are EPA blindly ticking off Utilities > Mass extermination & Bay Erosion...
Are we seriously culling Moreton Bay Wildlife to give a free ride to Olympic Size Port of Bne.

Coz it sure does seem like that... (Ultra poor timing & management will end these poor critters!)
Green Games they say...more like Joh piloting his White Shoe Brigade to feed the Chooks.
Perhaps not much we can do about it...but not gonna ignore the Brizzo's White Water rafting!

So there ya go...none of this makes any sense...but we Qldurrz still gotta sniff it out it & wade thru it!
Nothing is ever as it seems 'round these parts...all know it...we're just sick of dredgin' up the dregz.

It takes 1.5-2 hours to get out of Moreton Bay from Port of Bris. Ain't no way any military strategist would want that. They need immediate deep water access so there will never be a sub base at Bris. Wollongong would be way better.

I can think of better ways to spend the money as this is not a long term solution as seen by millions wasted on the gold coast.
Build a 150m pier out to sea that attracts marine life and creates the natural sand build up around itself and a great surfing destination in both northerlies and southerlies.
I am sure they will still go ahead and throw our money into the sea only to see the next swell wash it away.
Learn by your mistakes .

That is a very good point the crew have raised...
Qldurrz will share a secret...this seemingly gentle bay is not what it seems...

Mooloolaba wave lip pitches square & is renowned as Qld's heaviest shorebreak slabs.
Here's how & why...
Maroochy River > Headland > Bommies # Sloped Slabs # Breakwall < Mooloolah R < Point Cartwright
Cyclone brews all that fuel into the one cove = Whamo! # Mooloolaba Shorie # lights up SEQ!
Courier Mail swears it's notorious for spinal injuries! Few Qldurrz would doubt that!

Big Right Slabs ( tbb has clocked that it's often the Peak swells shaping as most rideable )
Can sit on the edge of yer seat & DJ the web cam..."C'mon...Just go the freak sets FFS!"
Naturally this Cyclonic shorie looks doable & beckons the dare devils...(Crunch Time!)

A better name for this is long shore drift. It builds up the beaches at the same time which is much needed on the Sunshine Coast.

I think we learnt about that in grade 6 .

Crew thanks Sprout for sharing these all encompassing photos of the Project!
Lends a complete perspective to any shaping of inshore wave zone.
One would assume this first rainbow - bars the THSD Brisbane from any closer inshore deposits?

Dredging Debate (Sunshine Coast News)
Locals: (Prefer affordable & needed Dredging of blocked local bars as a priority?)
https://www.sunshinecoastnews.com.au/2022/11/14/sunshine-coast-news-lett...

One wonders about dredging Heavy 15m deep sand (vs) Surface Sand of the Bars?
Has the crew got a take on which sand best suits Beach reclamation?

Coz it seems a long way to haul heavier Sand & much harder to pump & ups the risk factor!
The deeper you mine the channel, the greater the health risk from a toxic minerals Rainbow Cloud.
Does heavier sand slow or weaken small waves & supercharge Pounding sets?
Extra heavy ammo fuelling a cyclonic shore break to pound heads into a cement like sea bed.
Be like surfing in Cement Mixer Barrels...where a wipeout brings on gravel rash!
eg: Blood dripping from Shredded Wetties!

Recall the last dredging spoils from Spitfire Channel were used as foundation.
They provided foundation for Bne Airport / Bne Port reclamation / Sunny Airport.
Are we seeing foundation sand for a future Beach build reclamation..
(tbb can't find any beach development or cushion pad for cruise ship tenders?) Local Crew can call this!

Coz as locals say...Why not simply rainbow the light'n'easy choked up bars?

Sunny Coast '6 page' Fact Sheets ( Doubt very much these PDF files link )
Google : [ Nearshore Beach Nourishment Trial ] - Sunshine Coast Council
file:///C:/Users/Owner/Downloads/SCC%20fact%20sheet%20Nearshore%20beach%20nourishment%20trial%20MAR2022%20(2).pdf

Fact Sheet Q&A
First Up (Sounds Harsh!) Port of Bne manage & overrule any local concerns for Beach.
If Brizzos wanna dig up shit in their front yard & toss it on your pristine beach...then suck it up princess!
Here's our Bill = $600,000 (Bummer!)
Port Dredge 'THSD Brisbane' promises not to Bully the town any closer than 100m from shore.

Trial is not intended to have lasting impacts good or bad on the surf but will be monitored.
Surf / Sand is monitored for up to 3 months > 2 months Data > Outcome early 2023.
Reef habitat is excluded > Eco 'surveys' will continue for 3 years
Turtle Nests in this locale have long been repeatedly relocated due to impacts of Bright Beach lights.
Shore Birds hang at the Bird Watcher Bars > Seagulls hang shit on the Clubbies! Not an issue!

Current Aims :
Indirectly identifies limited Access (Often!) Think : SLSQ Tractors / Storm Cleanup crews!
No surprise as Goldie likewise spent a fortune on fortifying main players SLSQ Beach access points.
This often requires longer parallel to ocean ramps to achieve 24/7 trajectory for Heavy Vehicles.
tbb is not saying for smoothing out access from Cruise Ships to Surf Club Parmie'n'Pokies.
Yes! SLSQ feature highly on TAG committee & selective limited beach access is a main focus!
There is a slight reference to defence of Recreation / Amenity / Paths / Roads / Structures

Future Aims
*POB Sand Sourcing Study > re : $600,000 / yr Channel spoils contract seems to underpin this Source?
Honestly! tbb can't see how Sunny is made to pay for Brizzo's hot mess! ( File it under Port Rort! )

Explanation : Goldie dredges Talle Creek yearly > Pumps & Hoppers Spoils for $500,000 / yr
Just saying there is no discount here + Local Sunny Bars remain silted? ( Sunny Locals are right! )
Read next...
*Mid 2023 Next Renourishment is dredged from Maroochy River Mouth > Spoils to same beach!
Dances around a yearly plan : (Nov POB Channel spoils > June Bar/s spoils) > Just how it reads!

*Q: Artificial Reef / Council : (No!) Too expensive > Don't stop Erosion > Effects are too localized!

*Retreat? (No!) Beach = $80m/yr > 1. Tourism 2. Hospitality 3. Event Money > (What about us locals?)

*Limiting Permanent Beach Access points ( Well the Locals did ask! %$#! ) re: Goldie example...
Deny [P] & entry = Privatized Beaches > Crowd all locals into [Pay P] Fines in Town / SLSC Pokies.

*Expect this current approach to continue for many years to come...
re: Suck up Brizzo's Olympic / ADF Port Spoils > Slow privatization of Beaches & Pay 2 surf!

*Construction of a Buried Seawall is the Last line of Defence
*Long Term Planning Horizons > Proactive & explore Value for Money ways to manage beaches!

So after lots of pressure, council have apparently decided to do the bleeding obvious and dredge from the Mooloolah river mouth instead of the spitfire channel...

From the below fb link:
"**** Update 1pm Monday > council have looked into our suggestions & we’re very happy to say they are now going to be using sand dredged from the harbour mouth to replenish beaches & it will be deposited north of cheesecakes giving beaches North Mbar, Alex & Maroochydore the opportunity to see more sand make its way onto the beaches.

https://www.sunshinecoast.qld.gov.au/Council/Planning-and-Projects/Infra...

Overview : [Click] FAQ [ 202KB] > ( Is the Sand Dirty or Contaminated?)
This was supposed to be a real simple quest...turned into an epic bipolar battle!

SCC : "Sand is taken from Fed/State Enviro approved Source!"
"The sand will be assessed as suitable for Offshore Placement by State EPA during Approval Process!"

Q: Why are they assessing Dredge Spoil Contamination during & not prior to Rainbow delivery?

Locals Claim : Dredge Spoils are Contaminated Heavy Metal Sludge from Shipping Channel!"

This requires Background Research on POB Maintenance Dredging to investigate Toxic Dredge Spoils.

Q: Is this even possible to research in Qld...tbb very much doubts such...
A: Yes! But the answer involves whole SEQ Resource Players & Industrialized Politics!

That's right...we gotta go round the Block & then again & under here & over there & back again!

Intro to The Bay
Ocean side is 120k Pleistocene (Analogous) or longshore or Sea Level in this case ...if you like!
Bay side is 7k Holocene (Delta) as in multiple river > Bay Scoured drop off Tidal Banks.
Not too hard to imagine more contaminants channeled & butted against inside of Sand bank
Modern Ships need 2.4m draft to seabed of 15m deep channel > Submarines need 20-25m

Could Toxic waste come from Ships!
Fed Bio Security now forbid Ballast exchange in protected Zones.
tbb understands some players like Home Port operators or Cruise lines may receive exemption!
News has often exampled Cruise lines hosing off any virus ya like into Port waters...no worries!
Let's say a few drums go overboard every now & then & possibly outta sight upon leaving the Bay.
Doubt if this is a Major source of Contamination in a Marine Park...(Too obvious!)

Each Larger Flooding Event impacts on Moreton Bay & Shipping Channels with more highly Toxic Silt.
Every Govt / Industry is to blame & all suffer more so each time.
Most of the Silt comes from Lockyer Valley Farm Belt & Dam Releases

1.4m square metres of this silt needs to be cleared from Bne Shipping Channels each Year.
https://www.brisbanetimes.com.au/national/queensland/brisbanes-oil-suppl...
Hence POB extend Powers from Sunny Coast > Dams > Crop Lands ( POB Boss all committees )
They even pay to mitigate up river erosion...to keep SEQ Trade Route open to the World
Wivenhoe Dam Overflow releases 60,000 Tonne / day of Sediment into the Brisbane River.

2012 Campbell Newman reversed Tree Clearing Laws resulting in 3x 300k/H loss of SEQ vegetation!

Moreton Bay / 15m deep Spitfire Channel lies in the Benthic Zone (2002 Test Example)
Fine Sand Content 6m 100% > 8m 80% >10m 50% >12m 30% > 15m 20% > 17m 10%
Correct! Only 10% of Current 15-16m Spit Fire Channel Spoils is Sand!
90% is Broken Shells / Grit / Rubble / Clay / Red Algae (Mud is now #1 M Bay Sediment)

Just this Spoil Content alone could blind or foul lungs of someone close to the Rainbow Spray.
More closely resembles blue sky mining than dredging.

But we're after the real mucky gross unhealthy Spoils...we gotta dig deeper!

Biblical Moreton Bay
Flooding & Polluting Events 1974 / *2009 Mass Oil Spill / 2011 / 2013 / 2017 PFAS / 2022

Tests 'mg/kg' (2002 Spitfire Channel > 2011 (Post Flood) Deception Bay) > Raw Sewage! (General)
'Raw sewage' results are included to test if overflows are a prime source of contamination.
These are the only nearest Tests for time & place...but they do reflect Epic Event Contamination!
Cadmium .01 > .01 > 7.4 (Don't freak out > Larger measure > as they're Raw Sewage)
Arsenic .23 > 3 > 18
Lead .79 > 3 > 202
Zinc 1.2 > 5 > 1,985
Chromium 1.8 > 8 > 314
Mercury .01 > n/a > 6 > (n/a > Ultra High Mercury on Deception Bay Map...Here)
Read the Deception Bay Chapter for Severe Mercury Risk to ecology in these waters! (Massive!)

https://eisdocs.dsdip.qld.gov.au/Sunshine%20Coast%20Airport%20Expansion/...
Sewage Mercury is ultra low by Comparison > least contributes to D Bay record Mercury Reading

So what's going on here is something much larger than sewage overflow (Correct!)

2002 Studies swear Pollution hugged the CBD River Mouth not North - but Epic Floods are expanding.
We're seeing Massive Flood Headwater Frontline Contaminants further out from City each time.

Mud or Pesticide Top soil is spreading at alarming rates...
eg: 1970 400sq/km > *2011 (50sq/km/event) > 2016 (800sq/km) > *2022 (5x 2011 = 250sq/km event)
Current Mud Total = Approx 1,100sq/km
*Epic 2011 Flood Takes around 7 years for seagrass to recover
https://www.uq.edu.au/news/article/2011/01/uq-experts-map-moreton-bay
*Epic 2011 Flood Takes 920 Dredge moves over 20 weeks to clear Shipping channels

Choose yer Fav Culprit for Massive Severe Mercury Risk near Bay Entrance...

New/Up Graded/Hydro Dams can flush excess waves of Mercury as far as outer banks!
Sewage Overflow > Shuts Waterways for 3 days > Needing all plants for a Higher Mercury deposit.
Lockyer Fertilizer + 75% runoff > like sewage ticks all same contaminants with massive silt reach.
Grain Port Loading / Transit may require watering or run off process > Toxic residue!
Shipping Anti Fouling agents contain High mercury & is nearest to Crime scene & was associated!

*10% of Oil sinks at time of incident
* Seabed Oil amounts to 2/3 of what Locals see & cleaned represents 1/3 of Oil spill)
*1 year after Spill the oil sinks to the seabed
* Any Flood silt encases the oil & weighs it down to the seafloor & smothers it!
*10 years on lives in livers of Fish & Drops to Ocean Floor via Poop / Plankton
*10 years on represents as 10x higher levels than previous.
*Takes 50-100 years to fully recover

Summary (Parts 1 & 2)
Moreton Bay Dredge Spoils are contracted to SEQ Builders + Piped to Port > Airports.(Expansions)
These Spoils are approved under pre multi Eco disasters 2002 EPA Testing...
Should post multi epic disaster period recent Testing find Severe Risk to Ecology...(As reported!)

Then not one Union could force their Truckies to pick up a load of Toxic filth at Port of Bne.
Therefore the Port of Bne needs an Offshore dumping Ground off some eroding shoreline.
Port of Bne had a perfect Beach in mind!

( Record ) Rain > Locker Valley Run Off > Dam Releases > Sewage > Silting > OIL > PFAS > Contamination.
No Spitfire Channel Contaminants have been Measured since 2002 ( Pre worst ever Epic Toxic Eco Disasters)
Project Team say they'll monitor Contaminants during Dredging .

21st Nov 2022
Locals say no need...Yer not dropping more Toxic Pay Loads onto SEQ #1 recreation beach!
That be how the Govt ran a mile when locals shirt fronted them.
No way do they want to test & stick a Toxic label on POB merch that they can't move!
Not being up for the fight have pulled back on Judge Sludge!
Gotta find another sucker...
