Australia's Age-Gate Push Is Working, But VPNs May Undo It

Australia's eSafety Commissioner has confirmed that 27 of the 30 most-visited adult websites accessed from Australia now require users to pass an age verification check before viewing content, a dramatic compliance shift that followed legally binding codes which came into force in March 2025.

What the March 2025 Codes Actually Require

The new rules are not voluntary guidance. They carry legal force, and they cover more ground than most people realise. Adult content platforms must verify a user is 18 or older before displaying pornography, extremely violent material, or content linked to self-harm. That obligation extends to AI companion chatbot services, apps designed to simulate human conversation or relationships, and to app marketplaces.

Before March 2025, no such legal requirement existed in Australia. Sites could, and largely did, skip the step entirely. The shift from zero legal obligation to 90 percent compliance in a matter of months is a meaningful policy outcome, even if three sites in the top thirty remain non-compliant.

eSafety's figures carry some credibility because the Commissioner's office conducted its own monitoring of the top sites rather than relying on platforms to self-report. Self-reported compliance numbers are notoriously soft in this space. Independent monitoring is a harder test.

The VPN Problem the Regulator Now Has to Solve

Here is the obvious gap. A Virtual Private Network, or VPN, routes a user's internet traffic through a server in another country, masking the true location of the device. A person in Melbourne can appear, to any website checking for Australian users, to be browsing from Texas or London. That matters because Australian age-gate rules only bind platforms to check users who appear to be accessing the service from within Australia.

VPNs are legal. They are used every day by adults for entirely legitimate purposes: private browsing, securing public Wi-Fi connections, accessing geo-restricted streaming content. Free VPN apps are a single search away, and many require no account or payment to install.

eSafety has confirmed it will assess whether VPN use makes the age-verification scheme effectively pointless for determined users. The regulator has not specified what enforcement response, if any, would follow from that assessment, and no timeline has been published.

That ambiguity matters. If a 15-year-old can bypass a compliant age gate in under five minutes with a free app, the compliance rate of 90 percent becomes a headline number that does not translate into the child-safety outcome the codes were designed to produce.

Which Control Is Actually Being Tested Here?

From a security-awareness perspective, Australia's age-verification scheme is essentially an access-control problem. The codes impose a perimeter check: verify identity before entry. But perimeter checks only work when the boundary is enforceable. A VPN dissolves the geographic boundary the scheme depends on.

This is structurally similar to a corporate network that requires multi-factor authentication at the front door but has no controls once a user is inside, or once a user bypasses the entry point entirely. The Verizon 2024 Data Breach Investigations Report found that stolen or misused credentials remain the leading path into protected systems, precisely because access controls that rely on a single verification step can be routed around. The lesson transfers directly: one control layer is never enough, regardless of whether the attacker is a cybercriminal or a teenager with a phone.

Parental controls set at the router or device level, and sustained conversations with children about online content, represent the second and third layers that a web-based age gate alone cannot replace. Age gates are a compliance mechanism. They are not a parenting tool on their own.

What Parents and Guardians Should Do Now

The 90 percent compliance figure is progress worth acknowledging. Most major platforms have responded to the legal requirement. But the three non-compliant sites still exist, VPNs are freely available, and verified adult accounts in a household can be borrowed.

Practical steps for families right now:

• Enable DNS-level filtering on your home router. Services like Cloudflare for Families (1.1.1.3) or OpenDNS block known adult domains before a page even loads, regardless of whether a VPN is in use on the device.
• Review device-level controls. Both iOS Screen Time and Android's Family Link allow content category restrictions and can limit or block VPN configuration apps.
• Talk about the why, not just the rule. Research consistently shows that children who understand the reasons behind online safety boundaries are more likely to respect them than children who encounter unexplained technical blocks.

Age-verification codes are one policy instrument. They work best as part of a layered approach that includes household-level technical controls and ongoing digital literacy conversations. Organisations working to build that kind of literacy at scale, including through security-awareness training programmes that now increasingly cover child online safety policy alongside corporate cyber risk, recognise that human behaviour is always the variable that technical controls cannot fully anticipate.

What Happens Next

eSafety has not set a public deadline for completing its VPN assessment. The broader compliance cycle under the March 2025 codes is ongoing, and the three non-compliant platforms in the top thirty are presumably subject to regulatory attention.

The harder question, whether any age-verification system that relies on geographic IP detection can be made robust against freely available circumvention tools, is not one regulators anywhere in the world have fully answered. The United Kingdom's Online Safety Act takes a similar approach and faces the same structural challenge. Australia is, right now, the most visible test case for whether mandatory age-gating can produce real-world child safety outcomes or whether it produces paperwork compliance while the enforcement gap does most of the work for the sites that would prefer not to check at all.
