There is quite a strong front tracking across the lower Tasman in advance of this high cell, along with a polar low, which will send some useful S swells our way before the high sets up a blocking pattern, which is expected to be reinforced by another large high next week.
A large but not especially strong (1029 hPa) high pressure cell is west of Tasmania and slowly moving E where it enters the Tasman and becomes very slow moving. That will be the dominant feature of our synoptic set-up for some time, with a classic summer wind signal of SE winds in the sub-tropics, tending NE through temperate NSW.

Give the end of the week a miss with the weekend coming in better (mainly for the South West).
The Mid Coast will bottom out as the South Coast provides the best conditions ahead of an average week next week.
The beaches will become much cleaner over the coming days but the swell will be on the edge of being too big and overpowering.
Moderate pulses of swell for most locations this week, a little slower and mixed next week.
A new S/SW swell sourced from a polar low will build across the coast into Tuesday, but local winds will create some issues on the surface.
Thursday is where things get a little more interesting.
The Indian Ocean remains in a progressive pattern with a large high pressure belt and zonal disturbances in the Roaring 40’s supplying moderate overlapping SW pulses on a 24-36hr basis. Basically, overlapping swell pulses from these zonal storms will hold moderate surf all week, with subtle ups and downs.
