I can recommend
http://www.d-d-photographics.com.au/ for grey import cameras.
I bought my 5DmkII and some other stuff there and if you're in Sydney it's great to be able to go into an actual shop and get the same prices as online.
BUT I have a friend who bought a 7D from them and it was a lemon, it got sent away to be fixed twice and each time it was away for over a month.
I guess you can get unlucky and I'm not sure how much better the experience would have been for him had it been a local stock camera.
