If it is PAL version which I believe the UK use also it will work fine. Games in the US however are a different version and will not work on Australian systems.
PAL and NTSC no longer exist and haven't existed for a few years now and on DVD's and games it has NEVER existed.
PAL and NTSC are ANALOGUE colouring systems and DVD's and games use DIGITAL colouring systems.
DVD's and games use Regional coding to determine whether a DVD or game will work in that particular region. The regional coding is as follows:
Region 0 - Informal meaning "playable worldwide". Region 0 is not an official setting; discs that bear the Region 0 have either no coding put into it or all regions coding put into it.
Region 1 - US, Canada, Bermuda, Caribbean, US Territories
Region 2 - Europe, Middle East, Egypt, Japan, South Africa,Swaziland, Lesotho, Greenland, French Overseas departments and territories.
Region 3 - South East Asia, South Korea, Taiwan, Hong Kong, Macau.
Region 4 - South America, Central America, New Zealand, Australia, Papa New Guinea and much of Oceania.
Region 5 - Bangladesh, India, Nepal, Afghanistan, Sri Lanka, Ukraine, Belarus, Russia, Kazakhstan, Pakistan, Africa (except Egypt, Swaziland, South Africa and Lesotho), Central Asia, Mongolia, North Korea.
Region 6 - China
Region 7 - Reserved for future use, MPAA related DVD's and "media copies" of pre-releases in Asia
Region 8 - International venues such as Aeroplanes, Cruise Ships, Spacecraft etc.
People only use the terms "NTSC " and "PAL" to distinguish between the US and the UK.
The Topic Creator needs to look for either Region 0 games or games that have Region 2/4 coding on them.
