You can pretty much only buy the flat terry or flannel nappies in shops and they are getting harder to find! Well wuality ones are anyway.
Most modern cloth are found on the internet. There are a few great sites, if you do a search on google for modern cloth nappies, there should be a site for Oz cloth nappy org, and they have heaps of links there.
I think there is a shop in richmond or somewhere similar that is actually selling some nappies from their shop..... Hopefulyl someone else will jump in and give you some answers.
