Google Warns Australian Bill Could Lock Teens Out of Gmail

Australia’s ongoing drive to police the digital world is colliding with the everyday tools millions rely on. What started as a clear push to shield young people from online harm now risks spilling over into routine inboxes, cloud backups, and personal chat apps.

During a Senate committee hearing in Canberra, Google issued a blunt warning about the federal government’s proposed Digital Duty of Care legislation. Without clear exemptions for private utilities, the company warned that online services might have to introduce strict age checks or block Australian users under 18 entirely from essential platforms like Gmail.

The clash highlights how quickly safety regulations can create unintended consequences when laws don't separate public social media feeds from private communication tools.

When Safety Rules Threaten Private Inboxes

At the center of the dispute is Canberra's plan to place a legal duty of care on internet platforms. Under the draft law, tech providers that fail to systematically protect young people from encountering harmful online material such as pornography face massive fines reaching up to A$109.2 million ($75.1 million).

While lawmakers designed the rules to rein in algorithms and public feeds, the draft language does not explicitly shield private communication tools. Because the bill requires companies to prevent anyone under 18 from running into adult content anywhere on their platforms, tech providers face a difficult legal dilemma.

Google’s regional head of policy, Rachel Lord, explained the problem directly to senators. If the law applies universally without carve-outs, companies could be legally forced to age-gate everyday services. That would mean demanding proof of age before letting a teenager open an email account, or scanning content such as personal files and private messages to ensure no harmful material passes through.

For Google, shutting under-18s out of email isn't an ambition; it is the worst-case compliance route if the alternative is facing catastrophic financial penalties.

Why Big Tech Is Pushing Back

Google is not alone in raising the alarm. Representatives from Meta, TikTok, and Snap also voiced deep reservations during the inquiry, warning that vague statutory definitions hand too much open-ended power to internet regulators.

The industry's core concern comes down to how compliance works in practice. If tech companies face massive fines whenever a minor encounters prohibited content, their safest response is over-censorship. To ensure an unverified teenager never receives an explicit image via email or direct message, platforms would need to scan personal attachments and private correspondence.

Google has urged lawmakers to narrow the bill so that mandatory age-verification rules apply strictly to platforms whose primary purpose is distributing adult material, rather than punishing general-purpose infrastructure used for school, work, and family life.

How the Proposed Rules Compare to Practical Realities

The Identity Bottleneck and the Path Forward

The debate in Canberra exposes the fundamental flaw in how traditional internet platforms verify who is browsing.

Under current Web2 systems, proving that someone is over or under 18 almost always means handing over sensitive documents: driver’s licenses, passports, credit card details, or facial biometric scans. Forcing young people to surrender government credentials or submit their inboxes to automated scans just to use email creates serious digital security risks, building massive databases of personal records that hackers love to target.

This is why modern digital identity frameworks, especially zero-knowledge proofs, are gaining attention in tech policy circles. With zero-knowledge verification, a user can mathematically confirm that they meet an age requirement without revealing their name, exact birthdate, or identity documents, and without having their private communications monitored.

The Digital Duty of Care bill passed the House of Representatives late last month and is now under scrutiny in the Senate, with a committee report due on November 20. Whether lawmakers adjust the text to protect basic communication services remains to be seen, but the debate has made one thing clear: protecting young people online cannot come at the expense of gutting their access to the modern digital world.
