Bigger Is Better: The Largest Animals In Australia

Uluru - Australia

This post was sponsored and provided by Travelbag – Australian holiday specialists. I spent a year in Australia experiencing all that this fantastic country has to offer, and saw three out of six of these animals. Three more to go… I need to get back!

Australia may be the world’s smallest continent, but it is home to some very large animals. It has a diverse geography that includes deserts, rainforests and mountains, and an even wider range of unique animals. We have created a list featuring Australia’s largest animals including mammals, birds, reptiles, amphibians, insects and fish.

Red Kangaroo

Australia’s largest mammal is the red kangaroo. The red kangaroo is the largest of Australia’s marsupials. This gargantuan mammal resides in central Australia and is capable of surviving in harsh arid environments.

These animals are an average of 1.5 meters tall and can weigh between 18 to 85 kg. Red kangaroo’s are protected by Australian legislation, but can be harvested for their meat and hide.


Australia’s largest bird is the emu. The emu is also the second largest bird in the world. It too has adapted to its surroundings. Emus live in pairs and can be found in the forest and woodland areas of Australia. This enormous bird can grow up to 1.9 meters tall. As they have such small wings, emus cannot fly but are very fast runners. Emus are farmed in Australia for their meat, leather and oil.

Saltwater Crocodile

Salt water croc. Evil bastards.

Australia’s largest reptile is the saltwater crocodile. This is the animal that makes Crocodile Dundee carry a knife, a big knife. These aggressive creatures are the largest reptiles in the world and can grow up to 7 meters long and can weigh a crushing 2,000 kg. The crocodile is an apex predator with the strongest bite of any hunter. These territorial creatures live in the north of Australia.

White-Lipped Tree Frog

Australia’s largest amphibian is the white-lipped tree frog, also known as the giant tree frog. This frog is the largest and most recognised frog in the world. Females are normally bigger than males and can grow up to 5 inches long. The white-lipped tree frog has large toe pads as it can climb as well as jump. These amphibians can live for up to ten years in the wild, and if you have the right permit in Australia, they can be kept as a pet.

Titan Stick Insect

Australia’s largest insect is the titan stick insect. It has an average body length of 27cm. These insects have two sets of wings that look similar to a moth’s wing. Again, these species females are larger than the male. The Titans are masters of camouflage, but will use their wings to startle predators.

Murray Cod

Australia’s largest fish is the Murray cod. The Murray is bulky a freshwater fish that has the capacity to grow over a meter in length. This fish is an apex predator, devouring anything it finds that’s smaller than itself. It has been known to consume ducks, snakes and frogs. The Murray is featured in Aboriginal mythology that depicts this fish as being the creator of the Murray River.
