Sunday is a different story. The most powerful front in the series sweeps up past the state with severe gale to storm force winds sling-shotting around the parent low.
Strong high pressure support from a 1033hPa elongated high in the Bight is providing tight pressure gradients for the multiple fronts spinning off the gyre. That will lead to numerous over-lapping S’ly pulses over the coming week with a general step-ladder effect expected at least through to Mon. A general offshore flow will accompany these pulses as the fronts drive W’ly biased winds across the temperate to sub-tropical East Coast.
I can't remember forecasting such a sustained run of large, stormy surf for the South Arm.

We've got god pulses of W/SW groundswell due over the coming days but winds will be the main issue.
The onshore winds and average swells will persistent, becoming stronger later Sunday and into Monday as winds slowly improve.
Windy, cold and wet weather prevails with OK options for keen surfers in protected spots.
We've got successive increases in southerly swell due over the coming week, biggest on the weekend and early next week.
High pressure support along an elongated front and another deep low pressure gyre forming well South-east of the South Island super-charge a deep southern fetch Fri into Sat with an area of 20ft seas sling-shotting agressively North-east into the Tasman Sea.
Windy conditions with new swells on the way, spot selection will be key.
