the whole east coast of NSW has awesome waves and there all xshore in the right conditions.. the predominant wind here in summer is a north easter.. if you end up in sydney you may have to deal with crowded beaches.. the northern beaches are awsome but there is a lot of small beaches.. narrabeen and long reef are probably the best down there for kiting.. if you end up in eastern Sydney ie: Bondi, maroubra.. well i will give you $200 for your kiting gear. because you need permission to fart its that crowded..then there is southern sydney. mostly flat water down there and heaps of weirdo's

..but you can visit the home of Ivan Malatt on your way to some pretty nice surf beaches..as far as SA goes.. i know there is awesome waves there and its suppose to be a great place to live. but i have only ever been there a few times.
