Animals of the North West


Mammals and Marsupials

Australia’s North West is home to an amazing array of mammals, from wallabies, possums, dingoes, euros, flying foxes and quolls to nocturnal species like sugar gliders and the endangered bilby and bandicoot.

Many species of small carnivorous marsupials also exist here, including dunnarts and the pebble mound mouse. Fortunately, many of these species have been saved from extinction because the introduced European fox cannot live in the warm northern climate.

Poisonous and Dangerous

Australia’s North West is home to some of the most poisonous and dangerous animals on the planet. Although most injuries occur when the animal is reacting defensively to what it perceives to be an attack. See the health and safety section for advice and tips to ensure you have a safe and enjoyable trip.


The tiapan, king brown, western brown and death adders are common in Australia’s North West. All snakes are protected species, so if you see them steer well clear and never try to kill them.


The northwest is home to freshwater (Johnston) and Saltwater crocodiles, locally known as ‘freshies’ and ‘salties’. Freshwater crocodiles are found in freshwater pools, billabongs, creeks and rivers. They are generally considered harmless, feeding on fish, frogs, bats and birds.

Saltwater or estuarine crocodiles are considered extremely dangerous. They inhabit both fresh and salt water tidal rivers, billabongs, creeks and open waters. Growing to over seven meters long, these animals are supreme hunters, both on land or water. See the health and safety section for advice and tips about crocodiles.
