GTA Online players in Australia have reportedly found themselves suddenly barred from the litany of in-game gambling minigames found in Los Santos' Diamond Casino, with the change seemingly the result of developers Rockstar adding the country to their list of places where access to such minigames is restricted. Any Australian players approaching these games are being served a notification which reads "this feature is not available for you". Said code also mentions a "GTAO_CASINO_HOUSE" as being restricted alongside the minigames, which at first I thought might hint at Australian players losing the ability to buy or access the Diamond Casino penthouse you can shell out for as a GTA Online home. However, based on Australian players' posts, it appears this only refers to the gambling minigames found within the penthouse itself having been locked off in addition to those on the main casino floor. It's worth noting the Diamond Casino wasn't a part of GTA Online at release, instead arriving as part of a heist-centred expansion in 2019.
