Governance and Performance

To be informed of environmental, economic, cultural, political and social issues impacting us.  Ensure our key sustainability aspects are continued within our decisions.

The Issue

It is important to us that we maintain strong relationships with its stakeholders and the communities we operate in. Relationships based on trust, accountability and transparency need to be fostered. Our social license to operate is based on our stakeholders remaining confident in our brand and reputation which is based on our actions. It is important to benchmark our performance for sustainability and apply best practice principles.

There are more eyes our sustainability performance than there ever has been. With the ease of which information about our actions can be accessed or distributed we as a government organisation are at a heightened level of scrutiny. Without a high level of transparency on material sustainability issues we are at risk at being implicated publicly for environmental, social and governance failures should they occur. For example, if we have not demonstrated acceptable levels of performance as being an environmental steward why would we not expect scepticism and criticism in the public eye if an incident should occur. High levels of governance for sustainability and reporting is needed to provide context and a mature dialogue on our key aspects or risks.

For our long term success, the seamless integration of environmental and social risks and opportunities into our long term business strategy is vital. Understanding how our economic, social and environmental systems interrelate, affect one another and ultimately impact our business will only serve to improve business performance and the way in which we serve our community.


What we're doing

Global Reporting Initiative Reporting

Our commitment to best practice reporting is evidenced through our Annual Report which is compiled in accordance with the principles of the Global Reporting Initiative (GRI). We adhere to the GRI principles of stakeholder inclusiveness, materiality, completeness and context and as an ongoing commitment to ensure the validity of these topics to our business and stakeholders we conduct a biannual desktop materiality review which is reported to our Corporate Executive. The review draws from our corporate commitments, our key business and environmental risks, our corporate stakeholder engagement processes and media and ministerial topics.

Infrastructure Sustainability Council of Australia Membership


We are a member of the Infrastructure Sustainability Council of Australia (ISCA) which has developed the Infrastructure Sustainability (IS) rating scheme. The IS rating tool is Australia’s only comprehensive rating system for evaluating sustainability across design, construction and operation of infrastructure. As part of our ongoing commitment to delivering sustainable outcomes all major projects that:

  • Have a value greater than $100 million are to be formally assessed and rated by the IS Rating Tool; and
  • Have a value between $20m and $100m are to use the IS Rating Tool but not be required to undergo formal verification

Supporting schemes such as the IS rating tool directly links to our current approach to Sustainability. We supported the tool development by participating in pilot trials of various versions of the IS Rating Tool and by providing resources for the Working and Advisory Groups that ISCA facilitates as part of their program of tool development and improvement.  


The Numbers

Details of progress and achievements as part of our sustainability strategy can be found within our Annual Report and in our GRI content index. As at 30 June 2017, we have the following projects registered and rated under the IS rating scheme.
