2.5 million square kilometres of incredible biodiversity.

While Western Australia covers one third of the Australian continent, over half of the nation’s biodiversity hotspots and a significant percentage of its unique flora and fauna thrive here.

As well as being home to iconic Australian animals, such as red kangaroos and crocodiles, WA has 141 of Australia’s 207 mammal species, 439 reptile species, 1,600 fish species and more than 12,000 species of wildflowers – making it the largest collection of wildflowers in the world.

Life in the ocean

Along 20,781 kilometres of coastline, including islands and archipelagos, you’ll encounter wild dolphins, migrating whales and some of the most diverse marine environments on Earth.

In fact, one of 18 global hotspots of coral reef diversity stretches hundreds of kilometres from World Heritage listed Ningaloo Reef (the world’s largest fringing reef) and Shark Bay, to Rottnest Island near Perth.

Ningaloo and Shark Bay bring you breathtakingly close to turtles, dugongs, reef sharks, manta rays and the largest fish in the ocean, the whale shark.

Life in the forest

WA’s forests evolved in geographic isolation, which means much of its flora and fauna is found nowhere else on Earth, including the jarrah, karri, marri, tingle and tuart trees and many of the State’s 12,000 species of wildflowers.

The national parks of Perth, Dryandra and the South West offer windows to these unique forest habitats, not to mention rare Australian wildlife and one of the world’s 34 biodiversity hotspots.

See Forests and Parks for more information.

Life in the outback

In the central heart of WA lies Golden Outback – the largest expanse of outback in the country. Here, wide-open desert landscapes and plunging gorges provide natural habitats for a vast array of wildflowers and wildlife, from red and western grey kangaroos to the State’s rare national emblem, the numbat.

Dawn and dusk are when Australian animals are at their most active, but any time of day is good for going crocodile spotting in the Kimberley with an experienced tour guide.
