Australia is home to some of the world's most unique and fascinating wildlife. From the iconic kangaroos and koalas to the elusive platypus and echidna, Australian animals captivate visitors with their distinctive features and behaviors. Having evolved in isolation for millions of years, approximately 87% of Australia's mammals, 93% of reptiles, and 45% of birds are found nowhere else on Earth.
In this guide, we'll explore the best places and ways to encounter Australian wildlife in their natural habitats, as well as some ethical wildlife sanctuaries where you can get up close with these remarkable creatures.
Iconic Marsupials: Kangaroos, Wallabies, and Koalas
Australia's marsupials—mammals that carry their young in pouches—are perhaps the country's most recognizable animals.
Kangaroos and Wallabies
With over 60 species of kangaroos and wallabies (collectively known as macropods), these hopping marsupials can be found across much of Australia. While the Eastern Grey Kangaroo and Red Kangaroo are the largest and most well-known, you might also encounter smaller wallabies, wallaroos, or the tiny pademelon.
Best places to see kangaroos in the wild:
- Lucky Bay, Cape Le Grand National Park (Western Australia): Famous for kangaroos lounging on pristine white beaches
- Pebbly Beach, Murramarang National Park (New South Wales): Known for its friendly kangaroos that often interact with visitors
- Grampians National Park (Victoria): Home to large mobs of kangaroos in natural bushland
- Flinders Ranges (South Australia): Red kangaroos against the backdrop of the outback's red earth
- Namadgi National Park (Australian Capital Territory): Eastern Grey Kangaroos in abundance just outside Canberra
Tips for responsible kangaroo encounters:
- Observe from a respectful distance—generally at least 15 feet
- Never feed wild kangaroos; human food can cause serious health problems
- Be especially cautious around male kangaroos (boomers), which can be territorial
- Drive carefully at dawn and dusk when kangaroos are most active
Koalas
The sleepy, tree-dwelling koala is among Australia's most beloved animals. Despite often being called "koala bears," these marsupials are not related to bears at all. Koalas spend most of their time in eucalyptus trees, sleeping up to 20 hours a day as they digest the toxic eucalyptus leaves that make up their diet.
Sadly, koala populations have declined significantly due to habitat loss, disease, and the devastating bushfires of 2019-2020. They are now listed as endangered in parts of eastern Australia.
Best places to see koalas in the wild:
- Kennett River, Great Ocean Road (Victoria): One of the most reliable spots to see wild koalas
- Magnetic Island (Queensland): Home to a healthy population of approximately 800 koalas
- Raymond Island (Victoria): A small island with a thriving koala population
- Kangaroo Island (South Australia): Known for its genetically distinct koala population
- Port Stephens (New South Wales): Several koala habitats with guided tours available
Tips for spotting koalas:
- Look up! Koalas spend their time high in trees
- Search for them during the day when they're sleeping (they're nocturnal but visible during daylight)
- Scan for a round, grey ball-like shape in eucalyptus tree forks
- Learn to identify their preferred eucalyptus species (mainly manna gums)
- Join a guided tour with experts who know where resident koalas live
Monotremes: Nature's Oddities
Australia is home to the world's only monotremes—egg-laying mammals—the platypus and echidna. These creatures are so unusual that when European naturalists first encountered them, they were suspected of being elaborate hoaxes.
Platypus
With its duck-like bill, beaver-like tail, otter-like feet, and venomous spurs (on males), the platypus seems like a creature designed by committee. These shy, semi-aquatic mammals are found in freshwater systems along the east coast of mainland Australia and in Tasmania.
Best places to spot platypuses:
- Eungella National Park (Queensland): One of the most reliable platypus viewing spots in Australia
- Lake Elizabeth, Great Otway National Park (Victoria): Dawn and dusk canoe tours offer excellent platypus watching
- Platypus Reserve, Bombala (New South Wales): Purpose-built viewing platforms
- Warrawong Wildlife Sanctuary (South Australia): Protected habitat with regular sightings
- Mountain Valley, Tasmania: Private property with guided platypus spotting
Platypus viewing tips:
- Visit at dawn or dusk when platypuses are most active
- Look for ripples on the water's surface and bubbles
- Stay quiet and still—they're extremely shy and sensitive to noise
- Bring binoculars and patience; sightings often last just seconds
Echidna
Short-beaked echidnas, with their spiny coats and long snouts, are more widely distributed than platypuses and can be found across mainland Australia and Tasmania. These unique creatures feed primarily on ants and termites, using their long, sticky tongues to capture prey.
Where to spot echidnas:
- Kangaroo Island (South Australia): High echidna population with frequent sightings
- Maria Island (Tasmania): Echidnas often seen along walking tracks
- Blue Mountains National Park (New South Wales): Regular sightings along walking trails
- Alpine National Park (Victoria): Home to the mountain echidna subspecies
Echidnas are more frequently spotted than platypuses, often waddling across trails or roads, especially after rain when they forage for insects.
Reptiles: Ancient Survivors
Australia is home to an impressive diversity of reptiles, including some of the world's most venomous snakes, enormous saltwater crocodiles, and the iconic frilled lizard.
Crocodiles
The fearsome saltwater crocodile ("salty") is the world's largest reptile, with males growing up to 6-7 meters in length. These ancient predators inhabit Australia's northern coastal areas, from Western Australia's Kimberley region through the Northern Territory to northern Queensland.
Best places for crocodile spotting:
- Kakadu National Park (Northern Territory): Yellow Water Billabong cruises offer excellent croc viewing
- Daintree River (Queensland): River cruises with experienced guides
- Adelaide River (Northern Territory): "Jumping crocodile" cruises where crocs leap for food
- Malcolm Douglas Crocodile Park (Western Australia): For a safer up-close experience
"Always be 'crocwise' in northern Australia. Never swim in areas that might contain crocodiles, observe warning signs, and remember that absence of signs does not mean absence of crocodiles."
Other Remarkable Reptiles
Australia's reptile diversity extends far beyond crocodiles. Look out for:
- Frilled Lizard: Best spotted in northern Australia, this lizard displays an impressive neck frill when threatened
- Thorny Devil: A bizarre-looking desert-dwelling lizard covered in spiny projections, found in central Australia
- Blue-tongued Lizard: Common across Australia, these skinks display a bright blue tongue as a warning
- Perentie: Australia's largest lizard, reaching up to 2.5 meters in length, found in arid regions
Marine Life: Underwater Treasures
Australia's extensive coastline and the Great Barrier Reef host an extraordinary array of marine creatures.
Dolphins and Whales
Australia offers some of the world's best whale-watching opportunities, with annual migrations of humpback and southern right whales along both east and west coasts.
Best whale-watching locations:
- Hervey Bay (Queensland): Known as the whale-watching capital of Australia (July-November)
- Eden (New South Wales): Historical whaling town with excellent viewing opportunities (September-November)
- Albany (Western Australia): Where southern right whales gather in sheltered bays (June-October)
- Great Australian Bight (South Australia): Head of Bight offers clifftop viewing of southern right whales (May-October)
For dolphin encounters, consider:
- Monkey Mia (Western Australia): Famous for its wild dolphin interactions
- Port Stephens (New South Wales): Home to over 150 bottlenose dolphins

- Manta ray encounters: Lady Elliot Island, Great Barrier Reef (year-round)
- Sea lion swims: Baird Bay, South Australia, or Carnac Island, Western Australia
- Penguin parades: Phillip Island, Victoria, where little penguins return to their burrows at sunset
Bird Life: Feathered Diversity

Recommended wildlife sanctuaries:
- Healesville Sanctuary (Victoria): Specializing in native Australian wildlife conservation
- Currumbin Wildlife Sanctuary (Queensland): Features wildlife hospital and conservation programs
- Bonorong Wildlife Sanctuary (Tasmania): Rescue and rehabilitation center with guided tours
- Australia Zoo (Queensland): Founded by the Irwin family with extensive conservation work
