Infrastructure Development Fund - Stream 2: Unlocking Infill Precincts (2026)

The Infrastructure Development Fund's Stream 2: Unlocking Infill Precincts is an infrastructure investment program to address constraints in the water, wastewater and electricity network at a precinct scale to facilitate medium to high density residential infill development (i.e. in areas with an applicable density code of R30 or higher) within:

• The Central sub-region of the Perth metropolitan region
• The local government areas of the City of Cockburn, City of Kwinana and City of Rockingham
• Sites within one kilometre of Transperth train stations
• Sites within one kilometre of strategic, secondary and district activity centres
• Housing Diversity Pipeline sites; and
• The Bunbury central business district. 

This allows for larger, more complex infrastructure bottlenecks to be identified and addressed to provide the additional service capacity needed to unlock development opportunities. This is usually network operator designed infrastructure with capacity to service a precinct. Examples include a district transformer or the significant upgrade or extension of water or sewer mains. Without Government assistance, some of these development opportunities are unlikely to be realised or feasible for a single developer to coordinate and/or fund. 

Applications for this funding stream will be based on evaluation of a business case, including consideration of co-contribution opportunities with industry.

• Whether a co-contribution is proposed and the proportion of the co-contribution. 
• The degree of experience of the applicant(s) in developing medium to high density residential infill sites, and the timeframe by which development of medium to high density residential infill within the precinct could be expected to commence after the infrastructure project is delivered.
