Hi Carl,
I have done this research myself and generally found buying a grey import from china will be cheaper.
There are also companies here that import fro hong kong and provide very competitive prices to the au market.
E.g
http://www.dwidigitalcameras.com.au/store/index.asp is my favorite pals ATM. But I suggest you call first to confirm they have stock, otherwise. Hope your patient
Regards
Rob
