The Mathematics 2U 2002 HSC paper is on the main website and was done solely by Lazarus. It's very good.
As for Physics, you can get the SuccessOne Book. Or look at the exemplar answers on the main site. They are pretty big files though. (over 1 meg each question)
I have the SuccessOne book for Physics. If you are really desparate I guess I can scan the answers but will have to do it later tonight. Got to head of and do some study myself now.
