Just came across this and bought a copy from ozgameshop. This is one of the first times i can recall a game being cheaper in australia new than it is @ dvd.co.uk and the usual host of british sites. Pretty good deal considering free delivery. Sorry no PS3 version at this price i dont think!
AFAIK ozgameshop is a British outfit, they just list their stock in AUD. I've purchased from there before and received British stock. Good deal though. edit: Yup, they are UK based, check the site about page.
