Sustainability reporting

We provide regular reporting and seek to assist stakeholders to assess our performance over time and against key benchmarks.

We recognise the importance to our stakeholders of providing regular reports on our performance, and we apply and map against leading reporting standards. We continue to review our reporting to assist in ensuring we are meeting investor and stakeholder requirements.

Performance reporting

We report on the financial and ESG performance of our business.

Each year, interim reporting is released in May and annual reporting is released in November - with these disclosures including sustainability updates.

We apply external, leading standards to the development of our annual sustainability reporting as follows.

Global Reporting Initiative (GRI) Universal Standards (2021)

We have applied the GRI Standards since publishing our first sustainability report in 2002.

For more information on our application of the GRI Standards please see the ‘GRI’ tab in our Sustainability Index and Datasheet as part of our Annual Reporting Suite.

Independent Assurance

We have sought independent limited assurance over our sustainability reporting since publishing our first sustainability report in 2002. Our current assurance partner is PwC.

Our sustainability reporting is subject to independent limited assurance performed in accordance with the Australian Standard on Assurance Engagements 3000 Assurance Engagements Other Than Audits or Reviews of Historical Financial Information (Revised).

The GRI, Sustainability Accounting Standards Board (SASB), Task Force on Climate-Related Financial Disclosures (TCFD) and United Nations Environment Program Finance Initiative (UNEPFI) Principles for Responsible Banking (PRBs) are also used by our assurance provider as criteria against which to assess disclosures associated with alignment to GRI, SASB, TCFD and PRBs.

Refer to our latest performance reports for the most recent sustainability assurance report.

The most recent assurance opinion can be found in our latest 2023 PwC Sustainability Assurance Statement (PDF 180KB).
