This is an unusual swell source for the South Arm (and indeed, the entirety of Storm Bay) on a number of fronts.
Yep, we've got a whole stack of surf due next week, as a Long Wave Trough amplifies across the entire southern expanse of the continent.
A strong disturbance near Heard Island Sun/Mon generates seas to 30ft before being shunted southwards as it passes 90E. This will generate a series of SW swell pulses beginning Tues.
Pretty much nothing of interest for the rest of the week.
Our Coral Sea low is now sitting just NE of Tasmania where it has merged with an exiting interior low to form a large, slow moving low-pressure gyre. Troughs are still snaking across Australia with a long trough line extending from the low pressure gyre through inland NSW up towards QLD and then into the Northern Territory, expected to move offshore through today. More embedded troughs and fronts approach the Island during the rest of this week, driving an unstable but basically NW’ly to W’ly biased wind flow across the f/cast region through the end of the week with easing swells.

The next swell is already en route, generated by an intense polar low that had areas of storm force winds embedded in a large gale force fetch as it passed through Heard Island Sun/Mon.
The weekend looks alright. And, it looks like the Southern Ocean storm track will finally get back into a rhythm next week.
A sub-tropical low which threatened SEQLD and NENSW over the weekend after it formed off the Capricorn coast is now steaming southwards at a fair clip, sliding along a high pressure ridge from a large (1035 hPa) high under Tasmania and dragging a strong fetch with it into the East Tas swell window.
