There's the Arts Law website where you can get info and pay to download sample contracts.

And Simpsons are the arts laws specialists (national) (some of them do some work for the Arts Law associationa above too which is a lot less cost than going direct).

There's also the copyright council and publications
http://www.copyright.org.au/publications/books
where I purchased and downloaded some good info.
