Steam has introduced age verification for Australian users accessing R18+ games and other mature content, with Valve currently directing users to add a valid Australian credit card to their accounts. The change began appearing on September 9 as new age-assurance requirements for app distribution services took effect in Australia. Without verification, affected users can be prevented from viewing certain mature game store pages even if they are already adults or have used Steam for many years.
The restriction is tied to Australia’s Age-Restricted Material App Distribution Services Code, which requires app distribution services to take appropriate steps to prevent under-18s from purchasing or downloading R18+ apps. Australia’s eSafety Commissioner says the relevant age-assurance requirements for app distribution services had to be implemented by September 9, 2026. Steam itself is not classed as an age-restricted social media platform under Australia’s separate under-16 social media rules, so the new Steam restriction concerns access to age-restricted material rather than a general ban on younger users holding Steam accounts.
When an affected Australian user attempts to access mature content, Steam displays a notice saying Valve must verify that the person is at least 18 under the Age-Restricted Material App Distribution Services Code. The platform then instructs the user to add a valid Australian credit card and update their Mature Content Preferences. Reports from Australian users indicate that this can prevent access to the store pages of R18+ titles, including games already owned by the account holder, although it does not necessarily stop an already purchased game from launching.
The credit-card requirement has become the most controversial part of Valve’s implementation. Australia’s regulatory framework does not require companies to use one specific verification technology and allows methods including photo ID matching, facial age estimation, credit card checks and digital identity systems. Valve has nevertheless chosen a credit card as its currently presented verification route on Steam, while users have reported inconsistent results when attempting to use debit cards.
That distinction matters because many Australian adults use Visa or Mastercard debit cards without holding a conventional credit card. Some users have reported that particular debit cards have been accepted, while others say Steam continues to reject them for age-verification purposes, making the exact compatibility dependent on the card and issuer. Valve has not publicly announced a broader set of Australian verification methods at the time of writing, leaving some adult users unable to clear the restriction through their existing payment setup.
The rollout has prompted a significant backlash across Australian gaming communities, particularly from users whose Steam accounts themselves are more than 18 years old. Complaints have focused less on the existence of an age check and more on the limited verification options, with users arguing that long account histories or other forms of identity verification should be considered. Steam’s implementation also affects how Australians browse PC releases on a storefront that remains central to games such as The Witcher 3: Songs of the Past, where Steam wishlists and store visibility are important parts of pre-release discovery.
Australia’s eSafety guidance says the broader purpose of the Age-Restricted Material Codes is to reduce children’s exposure to material including pornography and high-impact violence while allowing adults to continue accessing lawful content. The regulator also states that services must minimise unnecessary collection of personal information and comply with Australian privacy law when implementing age assurance. The rules therefore establish the requirement for an effective age check, but individual platforms retain flexibility over how they satisfy it.
For Australian Steam users, that flexibility has resulted in a relatively strict system at launch: access to affected mature pages may depend on having a payment card Steam accepts as evidence of adulthood. The policy could still evolve if Valve adds further verification methods or adjusts card compatibility, but no such expansion has been officially detailed. For now, Australians encountering the new prompt will need to complete Steam’s age-verification process before normal access to covered R18+ store content is restored.
