Overview

Australia takes a technology-neutral approach to age verification. The eSafety Commissioner does not prescribe specific verification methods but requires platforms to implement "reasonable steps" to prevent minors from accessing restricted content. Industry codes developed under the Online Safety Act were registered in December 2025 and set out the practical compliance requirements.

Additionally, the Social Media Minimum Age Act — passed in December 2024 — bans children under 16 from social media platforms. Enforcement of this law began in late 2025. Platforms must implement age assurance and parental consent mechanisms to comply with the under-16 ban.

Australia's technology-neutral stance means any robust method that gives the platform reasonable grounds to believe a user is 18 or over will satisfy the Online Safety Act requirements.

Who needs to comply

The Online Safety Act applies to any platform accessible to Australian users that hosts or provides access to:

  • Class 1 content — content that would be refused classification under Australian law, including child sexual abuse material and extreme violence
  • Class 2 content — pornography and other restricted material that is legally available only to adults

Additionally, under the Social Media Minimum Age Act, all social media platforms accessible in Australia must:

  • Prevent children under 16 from creating or maintaining accounts
  • Implement age assurance systems capable of identifying users who are under 16
  • Provide a parental consent mechanism where the platform reasonably believes a user may be under 16

The laws apply regardless of where the platform is headquartered — if Australian users can access it, it is in scope.

  • Higher per-day penalties for corporations
  • Removal notices requiring the platform to take down non-compliant content
