That will be the dominant feature of our synoptic set-up for some time, which sees high pressure in the Tasman and a firm ridge up the sub-tropical coast and broad fetch of E-E/SE winds in the Coral Sea. 

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 beaches will become much cleaner over the coming days but the swell will be on the edge of being too big and overpowering.
