They're also having a 2 vita games for $48. But nothing is worthwhile.
You're better off buying Gravity Rush on its own.
I loved the game despite feeling that it was rather short.
DLC might be an issue as this is not oz stock.
Either way I heard that the DLCs out so far doesn't add to the main story.
AUS DLC works fine on UK copies of PS3/PSVita games 95% of the time.
