Central and Western Australia
Description
The Australian outback encompasses vast arid and semi-arid ecosystems dominated by spinifex grasses and mulga woodland. Marsupial herbivores and seed-eating birds form the primary consumer level, while dingoes serve as apex predators. Boom-and-bust rainfall cycles drive dramatic population fluctuations across all trophic levels.

- Spinifex grasses provide shelter for small mammals and reptiles
- Rain events trigger mass germination and insect emergence
- Wedge-tailed eagles soar to find carrion and hunt medium-sized mammals
