South Australia's share of national growth is set from the national drivers. This region's share of South Australia is built from development assessed on the ground.

Infrastructure (water, sewer) limitations are present across the region limiting the speed and ease of development. This was recognised by the February 2026 agreement between the SA State Government and the Australian government to provide extra finance to facilitate upgrades in a timely fashion.

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 |
|---|---|---|
| Gawler – Two Wells | 14.7% | |
| Playford | 46.5% | |
| Port Adelaide – East | 25.0% | |
| Salisbury | 10.6% | |
| Tea Tree Gully | 43.6% | |
| Adelaide – North total | 27.2% |
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 804 tracked residential development sites, so it counts what those sites can hold, not every theoretical dwelling a planning control would permit.
