Infrastructure Australia has completed its independent evaluation of the business cases for North Coast Connect and Sydney Metro Western Sydney Airport.

Based on the business cases and evidence submitted to us, Infrastructure Australia has determined that both proposals require further development to demonstrate sufficient return on investment.

Detailed business case evaluation summaries are available here, explaining how the proposals were considered based on the Infrastructure Australia Assessment Framework.

Our advice to government is updated regularly, therefore we welcome new submissions at any time.

We are committed to working closely with Australia’s governments to progress nationally-significant infrastructure proposals.
