The north-east sub-region in the Government�s draft Perth and Peel@3.5 million plan covers the City of Swan and the shires of Kalamunda and Mundaring.
Its population is expected to more than double to 450,500 by 2050, predominantly within the City of Swan, which will accommodate 60 per cent of residents.
Department of planning also predicts 83 per cent of the north-east population in 2050 will live and work in the same area.
Most of the future development will occur on land already zoned urban, including Caversham, Brabham, Dayton and Ellenbrook, as well as Gidgegannup, Stoneville and Parkerville.
Smaller areas at Bullsbrook, Midvale, Forrestfield, Stratton and Hazelmere have also been identified.
Planning Minister John Day said job growth in the north-east was tipped to revolve around new and existing industrial centres, robust transport infrastructure and proximity to major employment nodes like Perth Airport.
��Key employment areas will include the well-established centre at Midland; an emerging centre at Ellenbrook; the industrial hubs at Malaga, Forrestfield and Hazelmere; and attractors such as the Swan Valley,� he said.
�Proposed future industrial development at sites at Bullsbrook will also generate employment.�
The North-East sub-region covers the City of Swan and the shires of Kalamunda and Mundaring.
Mr Day said road networks would play a big role in the growth of the sub-region�s economic future.
Public transport details were scarce in the report but there was mention of a north-west region passenger rail with a spur line to Ellenbrook would be investigated for post-2031.
The WA Planning Commission is seeking public comment until the end of July.
