^^^ agreed.... and the season has been getting later so last few years mid Feb to Mid march was seeing at least 3 days a week wavesailing unless you're fat

but depends what you are into and your weight Sambo? Might need a bit bigger than Terrys suggestions above if you want maximise TOW.
SUP and snorkel is great at Corro when there is no wind.
Whereto stay again depends what you're into, if you have SUP, surf, 3 windsurf boards and 6 sails, you will on the water so much that would maybe mean camp at Corro as you will be on the water heaps .....but if you have one waveboard and only wanna do the 20-25kn days with swell, then maybe in town for some comfort and only sail Sunset...
If you can't get into Corro then camping at Oakabella homestead just to the north is very nice and not much of a drive each day.
Def try to be mobile as greenhead and lancelin just have to be done also
