Tom Clancy's HAWX for AUD$35 + postage - released at the start of the year for the Xbox 360,PS3 and PC, and fetching around $75 incl post on ebay, ~$80 at retail (slightly less at CDWow… hehe).
This is the Asian version, but is entirely in English and compatible with all XBox360s. It’s a decent game (75% avg on gamerankings.com); Shipping is only afew bucks more. Price is USD$24.90, which works out to about AUD$35 with the exchange rate currently, and postage is extra depending where in Oz you’re posting to.
This game's probably a bit too much for tradebait, but I've got the game for the PS3 and it's pretty decent by itself. Reminiscent of an arcadey version of Ace Combat.
Note that this is an affilliate link also.
I tried to trade in Midnight Club which was bought off Play-Asia. 3 EB games stores wouldn't accept it as it said NTSC-J on it even though it still worked. You might get lucky with some other stores. Other wise this is a good deal :)
