US Blu-Ray DVD's Work Here?

[5FDP]

I've been lent some PS3 games from the UK and I just inserted one of the disks into my AU bought PS3 and it's able to read it (currently installing update data) -- so yeah, it seems that PS3 games aren't region coded, but Blu Rays like DVDs are.

Yep, this is indeed the case.

I can confirm this also as I buy all of my PS3 games from the UK (ozgameshop) and have never had an issue.
