All the games should be region free, as well as that I am pretty sure that Aus/NZ are in the same Blu-ray region as the UK. (Region C)

http://en.wikipedia.org/wiki/Blu-ray_Disc#Region_codes

but it says region 2 for uk and region 4 for austraIia so will that not work?I would not want to get a ps3 in the uk and only be able to play the games as other reason is to play blu ray also,if i know the uk one works both games and blu rays purchased from oz then great.What to have a ps3 that plays both regions i suppose or there anything out there that allows the ps3 to be multi region with the blu ray,i think the games purchased in oz will work ok with the uk ps3 but will the blu rays work thats my question.

I'll take the PS3 off your hands to ease the headache of that bill a little !!!
