What is the financial risk for failing to block underage users?

Corporations face maximum civil penalties of $49.5 million, or 150,000 penalty units, for failing to take reasonable steps to prevent access. This enforcement regime begins on 10 December 2025 following a one-year grace period.

Is a simple age-gate pop-up enough to comply?

No, the regulator has explicitly rejected self-declaration as a sufficient standalone measure. Platforms must implement a layered approach including biometric estimation and document verification to meet the 16-year age minimum requirement.

How does the new law change how we handle user data?

Section 63F mandates the immediate destruction of personal information used for age verification once the check is complete. This creates a technical paradox where platforms must verify users but cannot retain the data needed to block them from re-registering with false details.

When will the government evaluate if these rules are actually working?

An independent review of the new Part 4A legislation is mandated for 2027. This review will assess the effectiveness of the technical requirements and the dual-regulatory roles of the eSafety Commissioner and the OAIC.
