Welcome mate! Theres a handful of us! Im from the outer burbs of Sydney myself, but my girlfriend lives in Brissie. I've found its far easier to play with modern cruisers such as your Dynos, Electras, Felts etc. Keep an eye on ebay and they come up regularly, just keep away from the cheapie stuff - you get what you pay for! We really dont have a heap of cool cantilever cruiser frames here, so we cant just go and pick them up at garage sales like our american cousins. Im positive some of the bike shops on the goldy would sell cruisers and accesories.
