Mandatory Climate Disclosure - Australia

Which AASB Reporting Group Are You?

Under the Treasury Laws Amendment (Financial Market Infrastructure and Other Measures) Act 2024, Australian entities must comply with the AASB S2 climate disclosure standard in three phased reporting groups.

AASB S2 Readiness Check

Are you checking for yourself, or a client?

This only changes what we suggest at the end.

Indicative only. Based on your responses and current Australian law. This is not legal, financial or compliance advice, and it is not an assurance opinion. Confirm your position with your adviser or auditor. AASB S2 is mandatory for applicable entities. AASB S1 is voluntary.

Enterprise scrutiny. Mid-market resources.

Many Group 2 and Group 3 companies face mandatory reporting and assurance expectations without enterprise-sized sustainability teams or budgets. SustainQ is designed for that operating gap.

Proposed changes, not current law

The May 2026 Federal Budget proposed changes to the large proprietary company thresholds. These changes are subject to consultation and legislation and are not current law.
