What’s ahead for Australia?
Australia’s sustainability and ESG regulatory landscape is entering a significant new phase. From 2026, a broader group of businesses will be subject to strengthened sustainability reporting, due diligence and assurance expectations, marking a shift from voluntary disclosure to mandatory, verifiable practice.
Here’s what’s ahead and what it means for your organisation.


Mandatory ESG Assurance
What’s changing: From the 2025–26 reporting year, large entities will be required to undertake mandatory ESG due diligence, with medium-sized organisations following from 2026–27.
What this means: Businesses will need to conduct ongoing ESG risk assessments, embed them into day-to-day operations, and demonstrate how ESG risks are identified, managed and monitored. In many cases, this will involve independent verification or third-party assurance over ESG disclosures.
Why it matters: These changes are designed to move sustainability out of standalone reporting and into core governance, risk and control frameworks, supported by phased-in mandatory assurance to improve credibility and consistency.
Climate-Related Financial Disclosures (CRFD)
What’s changing: Australia’s Climate-Related Financial Disclosure regime continues to expand. While large businesses have already begun reporting (from 2024), medium-sized enterprises will be brought into scope from 2026.
What this means: Organisations will be required to disclose climate-related risks and opportunities, including governance arrangements, risk management processes, transition planning and relevant emissions data, aligned with the Australian sustainability standards.
Why it matters: Climate risk is increasingly recognised as a financial risk. Integrating climate considerations into financial planning and public disclosures will be critical to meeting regulatory expectations and maintaining stakeholder trust.
Modern Slavery Act Reforms
What’s changing: Proposed reforms to Australia’s Modern Slavery Act are expected to be phased in from 2026, strengthening reporting obligations and enforcement mechanisms.
What this means: Reforms are likely to introduce more rigorous and standardised reporting requirements, mandatory due diligence, potential monetary penalties, and enhancements to the public modern slavery reporting repository.
Why it matters: Businesses will need stronger systems to identify, assess and address modern slavery risks across their operations and supply chains, supported by clear evidence and improved governance processes.
