What is a good place in Australia for sportswear?

yeh rebel sport is the big one, along with sportsco and various other chain stores. It's easier for you to go to a store to get something specificaly. eg, basketball isn't really that popular, so rebel sport would be a place to go to as they might have it. BUT if you wanted AFL or Rugby gear, you can find it at any sports store, online, direct from the club or at specialty stores.
