In this report, priority has been given to issues that we consider to be of material significance to our sustainability performance. We have determined these material sustainability issues based on a range of internal and external considerations, including:

• Concerns raised by stakeholders during the reporting period (see Stakeholder Engagement)
• Challenges facing the mining industry, identified through our participation in industry associations
  
• Our commitment to industry standards, including the International Council on Mining and Metals (ICMM) Sustainable Development Framework and the Minerals Council of Australia’s Enduring Value
  
• Our core values
  
• Our sustainability objectives outlined in our new Sustainability Policy
