If u mean the Central Coast of NSW then try Toowoon Bay near the Entrance in a southerly wind. Sailed there 2 day with only 4 other guys on a 4.2m sail & 75lt board. Waves were a bit flat but some nice jumps to be had. Also because its a bay u can blast around inside on the flat then when more confident u can head out past the point for some jumps & waveriding.

Fast
Good cross off in a NE wind, waves can be good but it has a fair sweep down the beach. Otherwise it is excellent but its a national park so it costs $$$ to get in. after 4pm I dont pay as the ranger is usually gone home.Can get 1/2 dozen guys in a session down there.
Another place a bit further south is soldiers beach which is near Norah Head lighthouse. If the swell is from the south, and a good NE is blowing, it can be all time down the line waveriding
Just 2 places I sail but there are more in a relative short distance from these 2.

Thanks Yagon, that gives me a few more options....

i can't help myself because i love this region:

central coast sailing is underrated - the N'Easter is as strong as wanda/botany bay because of the flat terrain around the lakes

the NE wind is strongest after 4pm
