Koalas are not bears — they are marsupials found only in Australia. They sleep up to 22 hours per day to conserve energy from their eucalyptus leaf diet, which is toxic to most other animals. A special organ called a caecum detoxifies the leaves. Koala populations have declined by over 30% in the last three generations due to habitat loss, disease, and bushfires.
New South Wales is home to several species of kangaroo, including the Eastern Grey and Red Kangaroo. These remarkable marsupials can leap up to 9 metres in a single bound and reach speeds of 56 km/h. Female kangaroos carry their joeys in a pouch for about 8 months. Wallabies are smaller relatives often spotted in bushland around Sydney Harbour.
The platypus is one of only five species of egg-laying mammals (monotremes) on Earth. Found in freshwater streams and rivers of eastern Australia, it uses electroreceptors in its bill to detect prey underwater. Males have venomous spurs on their hind legs capable of causing severe pain. The platypus is now listed as near-threatened due to habitat degradation.
Australia's saltwater crocodiles are the world's largest living reptiles, reaching up to 6 metres long and weighing over 1,000 kg. They have remained virtually unchanged for 200 million years. Found primarily in northern Australia, "salties" are ambush predators with the strongest bite force ever recorded — over 3,700 PSI. Conservation efforts brought them back from near extinction.
Australia is home to over 860 reptile species, more than any other country. The inland taipan possesses the most toxic venom of any land snake — enough to kill 100 adult humans in a single bite. The blue-tongued skink uses its vivid blue tongue to startle predators. The frilled-neck lizard raises its impressive collar as a defence display. Despite their fearsome reputation, snake bites are relatively rare.
Every year between May and November, over 40,000 humpback whales migrate along the NSW coastline — one of the world's most spectacular marine migrations. They travel from Antarctica to the warm waters of Queensland to breed and calve, then return south. The best viewing spots around Sydney include South Head, North Head, Cape Solander, and the Royal National Park coastal walk.
Common wombats are powerful burrowers native to southeastern Australia, creating tunnel systems up to 200 metres long. They are the only animals in the world that produce cube-shaped droppings — a trait thought to prevent them rolling away, marking territory more effectively. Bare-nosed wombats can weigh up to 35 kg and are surprisingly fast, reaching speeds of 40 km/h over short distances.
Sydney Harbour alone supports over 300 bird species. The sulphur-crested cockatoo is a ubiquitous sight, known for its intelligence and ability to solve complex puzzles. Kookaburras are famous for their "laughing" call that echoes through the bush at dawn and dusk. The superb lyrebird is one of the world's most impressive mimics, capable of reproducing the sounds of chainsaws, cameras, and other birds.
Australia's little penguins (formerly "fairy penguins") stand just 33 cm tall and weigh about 1 kg, making them the smallest penguin species on Earth. Colonies exist at Manly in Sydney Harbour — one of the few mainland urban penguin populations. They spend most of their day at sea hunting small fish, returning to their burrows at dusk. They can dive to depths of 70 metres.
Australian waters host over 180 shark species, from the massive whale shark to the great white. NSW uses SMART drumlines and drone surveillance to monitor sharks rather than traditional shark nets, significantly reducing bycatch. Grey nurse sharks, despite their fearsome appearance, are critically endangered in Australia with fewer than 1,500 remaining on the east coast.
Australia has over 700 species of eucalyptus, which dominate 80% of the country's forests. These remarkable trees produce oils that are both medicinal and flammable — a paradox that shapes bushfire ecology. Many species have evolved to survive fire, with thick insulating bark and epicormic buds that sprout new growth after burning. Eucalyptus forests support an extraordinary diversity of wildlife.
Australia has one of the worst mammal extinction rates in the world — over 30 species lost since European settlement. Conservation programmes across the country work to protect endangered species including the bilby, quokka, Tasmanian devil, and cassowary. Rewilding initiatives are reintroducing locally extinct species to fenced sanctuaries. Citizen science programmes allow anyone to contribute to wildlife surveys.
Make the most of your Australian wildlife encounters with these practical tips.
Many Australian animals are crepuscular — most active at dawn and dusk. Plan walks for early morning or late afternoon.
Australia's UV index is extreme. Wear SPF 50+, a broad-brimmed hat, and drink plenty of water, especially in summer.
Feeding wild animals is harmful and often illegal. Human food can cause disease and alter natural behaviours.
Use a 200mm+ lens for wildlife. Keep a safe distance. Mornings offer the best light and most active animals.
Stay on marked trails and wear closed shoes in bushland. Most snakes will flee if given the chance. Never attempt to handle one.
Spring (Sep-Nov) for wildflowers and baby animals. Winter (Jun-Aug) for whale migration. Summer for beach wildlife.
