GTA Online players in Australia have reportedly been locked out of the game's Diamond Casino gambling minigames, following what appears to be a deliberate change by developer Rockstar to restrict access for users in that country. The move follows Australian legislation introduced in 2024 that classifies simulated casino-style games as gambling-like content restricted to adults, alongside new online safety codes brought in this past March mandating age verification to protect children from age-inappropriate content, though Rockstar has not confirmed the reasoning.

The restrictions, uncovered via code found on the GTA Forums by dataminer Tex2, block Australian players from poker, blackjack, roulette, slots, the Inside Track horse racing minigame and the daily Lucky Wheel spin, with affected users shown a message stating the feature is unavailable to them. The block also extends to gambling games inside the purchasable Diamond Casino penthouse, though the penthouse itself remains accessible. Rock Paper Shotgun has contacted Rockstar for comment; it remains unclear whether the change is a delayed response to existing law or a pre-emptive move ahead of tighter regulation, raising questions about whether similar casino-style content might be scaled back or omitted in GTA 6.
