Australia’s Privacy Regulator Draws a Line on Age Checks as Online Verification Surges

Key Takeaways

• New Privacy Guidance Released: The OAIC has issued guidance to help organizations implement age assurance technologies while protecting user privacy.
• Post-SMMA Uptick in Age Checks: A surge in age verification activity follows the rollout of Australia’s Social Media Minimum Age scheme.
• Proportionality at the Core: Organizations are expected to justify the necessity of age checks and minimize data collection.
• Stronger Governance Expectations: The guidance emphasizes vendor oversight, risk assessments, and ecosystem-level accountability.
• Enforcement Risk Highlighted: Failure to comply may constitute a breach of privacy obligations and trigger regulatory action.

Deep Dive

The Office of the Australian Information Commissioner (OAIC) recently published new guidance aimed at helping organizations navigate the privacy implications of age assurance technologies. The timing is not accidental. In the three months since Australia’s Social Media Minimum Age scheme came into force, the regulator says it has seen a noticeable increase in age checks being used not just on social platforms, but across a wider range of online services.

That expansion has created a new kind of compliance pressure point, one that sits at the intersection of child safety, platform access, and data protection.

Drawing Boundaries Around Data Use

Privacy Commissioner Carly Kind framed the issue in straightforward terms. Organizations need to stop and think before reaching for age verification tools.

“Age assurance is not a blank cheque to use personal or sensitive information in all circumstances and must not erode Australians’ privacy rights,” she said.

At the heart of the guidance is a familiar but increasingly enforced principle. Necessity and proportionality. In practice, that means organizations are expected to ask whether an age check is actually required for the service they are offering, and if it is, to choose methods that collect as little data as possible.

It also means being upfront with users. If sensitive data such as biometric information is involved, the OAIC expects clear consent and no ambiguity about how that data will be used.

The Hidden Risk in “Simple” Solutions

What might look like a straightforward compliance fix on the surface often involves a far more complex backend. Many age assurance solutions rely on multiple providers, creating what the OAIC describes as a fragmented ecosystem.

That fragmentation matters. It introduces more points of failure, more data sharing, and more uncertainty about who is responsible for what.

The guidance makes clear that outsourcing the technology does not outsource the risk. Organizations are expected to carry out due diligence on vendors, understand how data flows across the ecosystem, and ensure appropriate security and governance controls are in place.

For GRC and third-party risk teams, it is a familiar story playing out in a new context.

Complaints Are Climbing and Regulators Are Noticing

The OAIC also pointed to a rise in complaints related to digital platforms, a signal that user frustration with opaque or cumbersome processes is growing.

In response, the regulator is placing renewed emphasis on accessibility and responsiveness. Privacy notices need to be clear and meaningful, not buried in legal language. And when something goes wrong, users should not have to navigate a maze to raise a concern.

Simple, accessible complaints mechanisms are no longer a nice-to-have. They are becoming a regulatory expectation.

What This Means in Practice

Rather than prescribing a single approach, the OAIC’s guidance outlines a set of expectations that organizations are expected to work through:

• Start with the question of necessity and build privacy considerations into the design from the outset
• Conduct due diligence across all providers involved in age assurance
• Choose methods that are proportionate to the risk and minimize data collection
• Obtain clear, informed consent when handling sensitive information, including biometrics
• Be transparent with users and provide straightforward ways to raise and resolve complaints

The consequences of getting this wrong are not theoretical. The OAIC notes that failures in this space may amount to an interference with privacy, potentially triggering compliance action or enforcement.

The OAIC confirmed that it will take another step later this year with the planned registration of the Children’s Online Privacy Code in December 2026.

For organizations, the direction of travel is becoming harder to ignore. Age assurance is evolving from a niche requirement into a standard gateway for digital services. But as it does, regulators are making clear that convenience cannot come at the expense of privacy.

The real challenge now is not just implementing age checks, but doing so in a way that stands up to scrutiny when the regulator comes asking why.
