Zone 1, sounds like you'll be close to Perth - within 5km's.
Pelican Point in Nedlands would be your best bet for wind/kitesurfing.
Take the train down to cottesloe or north fremantle for surf/wavesailing.
By a cheap surfboard (i'm selling 2 on here for $400

) and paddle out somewhere.
Just try not to get in the way of the other 2,000,000 people in the water in summer
