Make yourself a little trolley for your pushbike. Then you can get to rosebay and sail bondi in the southerlies.
Or you could just knick "skinny" Dans gear and take it for a spin... Last I've heard Dans local break is North Bondi. Unless it's blowing a NEer in which case it seems Dan abandons his family in favor of Wanda beach.
But seriously, giving Windsurf and Snow a call is a good start. They have plenty of great used good value gear (both boards and sails). I am sure Sam or Chris will be able to hock you up with some equipment. If you stay for longer you are probably better off buying some gear... It will be well worth your while over summer.
If you need to hire a car try Bayswater Car Rental in Kings Cross (they are based on William Street). You can get a 1 year old manual Toyota for about $150 a week there (or that's what it was when I last rented a car there). Probably the cheapest in Sydney unless you can get a corporate rate with on of the big agencies.
Sydney is great place to sail over summer... while it's not as constant as WA, when we do get a good summer it's just as good if not better given the proximity of good wave sailing to the metropolitan life style.
No matter were you go on the East Coast most people are happy to see other people on the water! Very different to WA let alone Europe.
