if u want clean, your gonna have to get up at the crack and hope for offshore - u may get it..... 50 /50.
north, will be better. have a drive up the coast road from trigg to sorrento, u will see where the surfers are,,, if its any good.
it will be nothing like ur used to, perth gets the scraps leftover from rotto and the outer reef system




perths best sup wave??? hmmmmmmmmmmm i'm gonna say dutch oven, out the back, on a freak once in a blue moon swell & g l a s s o f f
good luck
Bali will be better
