Hi Flaker, I live in Port Stephens (1/2 hour nth of Newy) and rotate between a 2/2 and a 3/2 and find them both fine for here. I just wear a hood and booties when it is really cold. I am originally from the Goldie and you just get used to the cold water after a while. We have had a good run the last couple of years with the water temp rarely dropping below 16c. I heard those new nineplus wetties on
www.wetfins.com.au/ are good.
Good luck
