Thursday is all about the strength of the southerly wind: we’re looking at 30-40kts+ at exposed coasts, and 20-30kts elsewhere.

There’s a chance that some locations in Far Northern NSW could see a window of excellent large surf as the swell starts to build later Wednesday.
The strong southerly groundswell currently pushing up along the Northern NSW will probably peak overnight, which is a shame as there’s a lot of size and strength in the water right now.
Friday still looks very interesting, with a very powerful front/low expected to track under Tasmania late Wednesday
Today saw very strong lines of S’ly swell in Southern NSW, and because of the origin, direction and trend, we can be reasonably confident that this swell will push across Northern NSW too.
This means we won’t see the resulting new southerly swell push up the Northern NSW coast until sometime Sunday - probably early to mid morning on the Mid North Coast, then early to mid afternoon across the Far North Coast.
A weak trough pushing off the NSW coast this evening now looks like it’ll display a minor E’ly thru’ SE fetch off its southern flank into tomorrow. This should generate a brief SE swell for Thursday though I can’t see anywhere north of about Coffs receiving much influence from it.
The synoptic charts make for pretty grim reading.
The final southerly pulse in this recent series is pushing up the Southern NSW coast today and will peak overnight or early Saturday across Northern NSW.
The low to the N/NE of New Zealand is still active out in our far east swell window though is finishing up swell production for us as it rotates clockwise out of our swell window.
