The Alinytjara Wiluṟara Landscape region is home to approximately 4000 people and covers more than 250,000 square kilometres in the north west quarter of South Australia. It stretches from the Northern Territory and West Australian borders south into the Great Australian Bight, including the state waters (three nautical miles off-shore). This huge region has been divided into nine sub-landscapes, each with distinct characteristics. This enables a more focused approach to be taken to planning, working on problems and reporting.
The nine sub-landscapes are:
- Bunda Cliffs (including Merdayerrah Sandpatch)
- Yalata Coast
- Nullarbor Plain
- Yalata Lands (including Colona and Pintumba)
- Yellabinna and Yumbarra
- Great Victoria Desert
- Southern APY
- APY Ranges
- Eastern APY and Tallaringa
NOTE: Since July 2020, parks and reserves in the region are managed by National Parks and Wildlife Service, with land management support provided by the AW Landscape Board.
