There’s a few groups like this in Australia, unfortunately.

Australia didn’t even have an R18+ rating for games until 2013 (R18+ is similar to AO or NC-17 in the USA). Before then, all games with a higher rating than MA15+ were illegal in Australia. Many games had an Australia-specific version with gore reduced, some things edited out, etc. to reduce the rating. The original release of GTA4 in Australia was heavily censored.
