POPULATION CHANGE IN THE REMAINDER OF WESTERN AUSTRALIA

Population growth

Between June 2001 and June 2011, the remainder of WA grew by 71,000 people (or 16%) to 520,100. This represented 22% of the state’s total population.

In the ten years from 2001 to 2011, the Pilbara recorded the largest and fastest population increase (23,300 people or 59%) for an SA3 outside of Greater Perth. Bunbury followed with the next largest increase (19,000), while Augusta - Margaret River - Busselton had the next fastest-growing population (31%).

In the ten years to 2011, Gelorup - Dalyellup - Stratham, in the south-west of WA, had the largest and fastest population increase (7,200 people or 242%) for an SA2 outside of Greater Perth.

Large population increases also occurred in Karratha (up 6,600 people) in the north-west of WA, Busselton (5,800) in the south-west, East Pilbara (5,700) in the north-west, and Australind - Leschenault (4,800) in the south-west.

Rapid growth was also recorded in East Pilbara (226%), Ashburton (76%), Karratha (63%) and Newman (57%), all located in the north-west region of the Pilbara.


Population decline

The Gascoyne was the only SA3 in the remainder of WA to decline between June 2001 and June 2011, down 690 people or 6.6%.

In the ten years to 2011, just over one-quarter of SA2s in the remainder of WA decreased in population, with the largest declines occurring in Manjimup (down 830 people or 13%) in the south-west, and Moora (down 770 people or 14%) in the northern wheatbelt. Other SA2s to experience large population declines were Merredin (down 670) in the northern wheatbelt and Carnarvon (down 610) in the Gascoyne.

The fastest declines were in the SA2s of Gnowangerup (down 16% or 530 people) in the great southern region of WA, and Mukinbudin (down 15% or 610 people) in the northern wheatbelt.

CENTRE OF POPULATION

At June 2011, the centre of population for WA was near the Avon Valley National Park, roughly 20 km west of the town of Toodyay. In the ten years to 2011, the centre moved 4.7 kilometres north-west, partly due to high population growth in the north of the state.

The centre of population for Greater Perth at June 2011 was just east of the Kwinana Freeway in the suburb of Como.
