I can't recommend Merlin Audio highly enough. As far as I know they're the only official Australian Oppo distributor and Ken does an amazing job with customer support. He's a good guy, and even though you didn't buy from him if you give him a call he might have a 3D set and be able to test a disc or two for you.
I'm also in Australia (Sydney) but I don't have a 3D set (I'm one of those backward guys who doesn't want one). All I can say is that I've never had any issues with playback of 2D discs (with a Bluraychip.dk mod kit installed). Everything works as it's supposed to.
I'm guessing your problem is 3D-specific as opposed to electricity-specific, but if you want to check with only Australian users, try dtvforums.info, where you'll find a good number of Australian Oppo owners.
