Hi Alex,
Welcome to ST.
You will be in Sydney in the middle of summer (more like Hawaii than Oregon) and the beaches will be great for cooling down.
Manly is a great tourist beach and you should get there by ferry from Circular Quay.
Bondi is also great for socialising (I'm not in the partying set, but this is its reputation).
The Sydney Harbour Bridge climb is a great experience if you have a spare $AU150.
Lots of visitors go to Darling Harbour with its shows and restaurants. They love it. I hate it. It is so obviously touristy and the restaurants are expensive with only average meals.
Australia has great food - Italian, Thai, Chinese, Greek, Vietnamese, French, etc. Buy a copy of "Cheap Eats in Sydney". We have great seafood so make sure you try some.
The Sydney Mardi Gras parade is on Saturday March 5. It's a great show, and you can be straight and still enjoy it.
It would be a good idea to cultivate some friends on your course. People who know you better can give more appropriate advise. If there are Sydneysiders, you might even get put up for your visit.
This is the
Australia Suggestions link that Carole refered to.
