As Australia prepares to implement its sweeping social media restrictions for minors, the federal government is escalating pressure on major tech platforms to close what it views as the most obvious loophole: virtual private networks, better known as VPNs. Officials say platforms must take “reasonable steps” to stop under-16s from using VPNs to bypass the ban, a demand that has triggered debate among privacy advocates, cybersecurity experts, and the platforms themselves.
The new law, set to take effect later this month, requires major social media services to block accounts belonging to users under the age of 16. The legislation marks one of the world’s most ambitious attempts to regulate young people’s online behavior, and the government argues it is necessary to protect children’s mental health and reduce exposure to harmful content. But critics warn that enforcement will be far more difficult than promised — and the call to tackle VPN circumvention has only intensified those concerns.
A New Battleground: VPN Detection
VPNs are widely used tools that allow internet users to mask their location and encrypt their traffic. For teenagers accustomed to navigating online restrictions, they are a familiar workaround. Government officials insist that allowing VPNs to remain an easy escape route would render the new age restrictions meaningless.
Though the legislation stops short of mandating specific technologies, regulators have made it clear they expect platforms to detect and disable VPN-based access in cases where minors are involved. In practice, that could involve monitoring suspicious login patterns, flagging frequent IP address changes, or using device-level location signals to ensure a user’s network traffic matches their physical position.
However, experts note that detecting VPN usage is anything but trivial. Some VPN services operate large networks designed to blend in with everyday web traffic, making them indistinguishable from normal internet usage. Stronger VPN detection may also demand intrusive levels of monitoring, pushing platforms into territory that many argue is incompatible with privacy rights.
Privacy Concerns Come to the Fore
The expectation that platforms should detect VPN use by minors has sparked a wave of concern among digital-rights advocates. They argue that requiring companies to routinely examine users’ traffic or track their precise location could amount to mass surveillance.
One of the most contentious issues involves deep-packet inspection — a technique through which platforms or internet service providers analyze data packets to determine whether they originate from a VPN. Although effective in some environments, DPI raises alarm bells due to its capacity to reveal more information than users intend to share. Critics fear that mandating or incentivizing such technology sets a dangerous precedent, opening the door to broader monitoring in the future.
There are also fears that, in their attempt to comply, platforms may over-correct by blocking legitimate VPN users of all ages. Millions of Australians rely on VPNs for work, online security, or to access region-locked media. Any misclassification could harm businesses, professionals, and privacy-conscious users.
A Ban That Could Backfire?
Despite widespread support for protecting young people online, many parents and educators remain skeptical about whether the ban will work in practice. Age verification itself presents a significant challenge. Platforms are expected to implement robust systems capable of accurately determining whether a user is under 16 — a task that no country has fully solved. Methods such as facial age estimation, ID verification, or AI-based behavioral analysis each carry their own risks, from accuracy issues to privacy implications to potential discrimination.
The push to restrict VPN access may inadvertently encourage teens to seek even riskier online tools. Security researchers warn that when youth are blocked from mainstream VPN services, they may turn to lesser-known or free providers that collect data, inject ads, or distribute malware. Some underground VPN services are explicitly marketed toward minors seeking to evade parental controls or geographic blocks, exposing young users to significant cybersecurity risks.
The Platforms’ Dilemma
The government’s position places significant responsibility on social media companies, many of whom privately describe the VPN expectation as unrealistic. While platforms have expressed support for child-safety initiatives, they argue that preventing VPN use is largely outside their technical control. VPN traffic is not inherently harmful, and differentiating between adult and minor users is challenging without intrusive verification systems.
Some companies also worry about conflicting global regulations. In Europe, for instance, data-minimization rules limit the types of information platforms can collect. Complying with Australia’s demands could put companies at odds with their obligations in other jurisdictions.
Nevertheless, given the penalties associated with non-compliance — including steep fines — most major platforms are expected to introduce some form of VPN monitoring or detection. How effective these measures will be remains uncertain.
The Countdown to Enforcement
With the enforcement deadline fast approaching, questions continue to mount. Parents are seeking clarity on how the ban will work in practice, young people are discussing potential workarounds, and legal experts are preparing for challenges that could arise once the law is tested.
The government maintains that its approach is both necessary and proportionate, arguing that the digital environment has become too harmful for children to navigate without stronger protections. But as the debate intensifies, it is clear that the success — or failure — of the under-16 social media ban may hinge on the very issue now under the spotlight: whether platforms can realistically stop minors from using VPNs, and at what cost to the privacy and freedoms of all Australians.
For now, the country watches as tech companies scramble to build new systems, regulators sharpen their enforcement strategies, and families brace for what could become one of the most significant shifts in how young people access the internet.
