A Public Private Partnership (PPP) is a proven infrastructure procurement method that is increasingly being used by governments
over the world alongside more traditional methods to deliver infrastructure to the community.  The aim of a PPP is to deliver improved services and better value for money primarily through appropriate risk transfer, encouraging innovation, greater asset utilisation and an integrated whole-of-life management, underpinned by private financing.

"Infrastructure Australia" published National PPP Policy Framework in 2008. It provides a consistent framework that enables public and private sectors to work together to improve public service delivery through private sector provision of public infrastructure and related services.
The objectives of the National PPP Policy Framework are to:
• encourage private sector investment in public infrastructure and related services where value for money for government can be clearly demonstrated;
• encourage innovation in the provision of infrastructure and related service delivery;
• ensure rigorous governance over the selection of projects for PPPs and the competition for and awarding of contracts;
• provide a framework and streamlined procedures for applying PPPs across Australia; and
• clearly articulate accountability for outcomes.
