Where can I find Australian guiness world record holders?

Anyone know any or know where I can find a list of people in australia who have made it into the book? I looked on their website but I can't really find anything decent. It's for a project I'm doing for class, with an Australian theme, and I wanted to do australian world record holders (not sporting records) But I can't find any.|||Steve Irwin was the first, I believe, to randomly tackle a crocodile. If not the first in the world, the first in his family!
