Our latest population and housing forecasts for Bunbury, which covers Western Australia's South West, including Bunbury, Busselton, Margaret River, Collie, Harvey, Waroona, Bridgetown, Manjimup and the surrounding shires.
Western Australia's share of national growth is set from the national drivers. This region's share of Western Australia is built from development assessed on the ground.

Since our last review of the region, there has been further acceleration of property development, fast-forwarding of land releases, and identification of additional capacity. In addition to the usual suburbs driving growth (various suburbs of Busselton, and those sprawling out of Bunbury), we have noted a surprising level of activity in relatively less known locations, such as the town of Capel and localities along the Bussell Highway south of Margaret River.

Different things drive population change at different scales. We form a view at each level, and each level constrains the one below it.
| Sub-area (SA3) | Area character | Capacity used by 2046 |
|---|---|---|
| Augusta – Margaret River – Busselton | 74.3% | |
| Bunbury | 39.3% | |
| Manjimup | 88.3% | |
| Bunbury total | 51.7% |
Capacity used is the share of an area's assessed dwelling capacity that the forecast draws down by 2046. Assessed capacity is post-census capacity across 378 tracked residential development sites, so it counts what those sites can hold, not every theoretical dwelling a planning control would permit.
