Perth and Peel @ 3.5 million frameworks

Information regarding Perth and Peel @ 3.5 million and the sub-regional frameworks.

The frameworks

The Perth and Peel @ 3.5million land use planning and infrastructure frameworks aim to accommodate 3.5 million people by 2050.

The frameworks define the urban form for the next 30 years, limit unsustainable urban sprawl and encourage greater housing diversity to meet changing community needs. They provide guidance and certainty to State Government agencies, local government and the development sector.

The frameworks determine where new homes and jobs will be located, make best use of existing and proposed infrastructure, and protect important environmental assets.

They set the groundwork for the development of vibrant new communities, particularly around key transport links, including METRONET station precincts and activity centres, within a compact and connected city.

They encourage significantly greater infill development with almost half of the required 800,000 new homes – 380,000 at a minimum - to be built through infill development. The majority of these – around 214,000 – will be built in existing suburbs within the Central sub-region and particularly through alignment with METRONET and the State Government’s Our Priorities: Sharing Prosperity initiative.

The frameworks are not static documents. They are monitored and reviewed to ensure they remain contemporary and responsive to Government priorities and community need. A  review is anticipated to get underway in 2021. 

Planning Investigation Areas

Considerable work has been underway since 2018 into all Planning Investigation Areas (PIAs) across Perth and Peel. PIAs are sites identified within the frameworks where further detailed planning needs to be undertaken to determine whether any change to current zonings is appropriate. 

The frameworks identify 15 Planning Investigation Areas and provide the following guidance:

  • Investigations will determine whether it is possible and/or appropriate to rezone the land.  
  • The PIA classification of a site should not be construed as support from the Western Australian Planning Commission (WAPC) for a change from the existing land use/zoning, as this will depend upon the outcome of the further investigations. 
  • Each site has key issues documented in the relevant planning framework to be considered as part of a WAPC-led work program.  
  • The outcome of investigations will be considered as part of the future review of Perth and Peel@3.5million.

The Department of Planning, Lands and Heritage has been working with other relevant agencies and local governments to progress these investigations.

Please refer to the following list of Planning Investigation Areas for more details.

Frequently asked questions

Why do we need increased density and infill development?

The Perth and Peel regions now stretch more than 150 kilometres from Two Rocks in the north to Bouvard in the south.

In 2010, Directions 2031 and Beyond proposed limiting Perth and Peel’s unsustainable urban sprawl by creating a consolidated and connected city and redressing the balance between infill and greenfield development to 47 and 53 per cent respectively. Perth and Peel@3.5million provides clear guidance on how this will be achieved through a coordinated, whole-of-government approach to land use and infrastructure provision.

Of the 800,000 new homes needed for the projected population increase, almost half – at least 380,000 or 47 per cent – will be provided through increased density and greater infill development in strategic areas such as around transport hubs, including the new METRONET station precincts and activity centres. Most of these will be built within existing suburbs in the Central sub-region.

Does every local government have an infill target of 47 per cent?

The infill target of 47 per cent is for all of the Perth and Peel to the year 2050. The Central Sub-region is largely developed, so all development for these local governments will be infill by default, which offsets the other sub-regions. Not all infill targets for local governments outside of the Central Sub-region are 47 per cent, with some being higher and others being lower. 

Will the frameworks affect housing affordability?

The frameworks aim to create thriving new communities and revitalise existing ones, particularly around key transport hubs including the new METRONET stations. It is expected that this will generate greater housing diversity and choice that reflect changing and evolving community needs and aspirations.

Greater housing diversity may result in improved housing affordability. Increased infill development should result in more people living closer to where they work, cutting commuting times and other costs associated with living on the urban fringe.

Can I appeal against a decision in the frameworks?

There is no appeal process for any of the frameworks’ proposals.

However, the frameworks are not static documents. They will be monitored continuously and reviewed to ensure they remain contemporary and responsive to Government priorities and community need.

What do these terms mean?
  1. Urban/industrial investigation – land that may be suitable for urban or industrial development but requires further investigation to determine its suitability.
  2. Planning investigation – land that will be subject to further investigation to consider its suitability for development
  3. Open space investigation – land that may be suitable for open space purposes but requires further investigation to determine its suitability.
What happens next?

These are long-term, strategic plans and do not automatically change the existing zonings and/or reservations of land, or allow for new land use. They are the next step in the ongoing process of refining and detailing planning proposals for Perth and Peel.

The need to provide land for development, landowner intentions, and the capacity of servicing agencies and local governments will guide the timing around delivery of the proposals. Future development is expected to be undertaken sequentially as logical extensions to existing development and an adequate supply of land will be continuously available.

State and local government planning bodies need to review and refine the urban form shown in their planning schemes and strategies, and maintain the spirit and intent of the frameworks through their planning decisions.


A review of the frameworks is scheduled to get underway in 2021 to ensure that they remain responsive to changes, challenges and community expectations as the regions develop.

The delivery of additional infill housing opportunities associated with METRONET and the Our Priorities: Sharing Prosperity initiative may lead to the need for revised infill targets and/or staging of greenfield development through the review process.

Monitoring and reporting will inform Government, industry and the wider community on the progress of delivering the frameworks. This will be integral to the practice of evidence-based policy interventions that can respond to the challenges of a rapidly-changing and growing city.

It is anticipated that a timeframe will be provided closer to the review date.
