Your complete guide to spotting wildlife on Rottnest Island

Just off the coast of Perth, Rottnest Island is a sanctuary where wildlife thrives in its purest form. With no cars, minimal development, and a network of protected habitats, the island offers a rare glimpse into Western Australia’s natural world. From the adorable Rottnest Island quokka, found nowhere else on Earth, to vibrant coral reefs teeming with marine life, every corner hums with life and colour.

Quokkas: The Island’s most famous inhabitants

The Rottnest Island quokkas are the island’s most beloved residents. They are small marsupials found almost nowhere else on Earth. When Dutch explorer Willem de Vlamingh landed here in 1696, he mistook these furry creatures for giant rats and named the island “Rattennest,” meaning rat’s nest which later became Rottnest. Quokkas are also known for their photogenic ‘smiles’ and in fact, their naturally upturned mouths and expressive faces have made them internet-famous and arguably the world’s happiest animal.

Where to find them?

These curious creatures roam freely across the island, often spotted around Thomson Bay, Settlement Mall, or dozing under shady trees near picnic areas. Early morning and late afternoon are the best times to see them when they’re most active and the light is perfect for photos.

Remember, do not attempt to feed or touch them. Quokkas are part of protected Rottnest Island wildlife, and keeping a respectful distance helps them stay healthy and wild.

Australian sea lions: The island’s playful locals

Among the most captivating Rottnest Island wildlife, the Australian sea lions are a delight to watch. These rare marine mammals found only along Australia’s southern and western coasts often haul up on the island’s rocky shores or bask lazily in the sun near Cathedral Rocks on the west end.

Graceful yet curious, they can often be seen gliding through the turquoise shallows or performing flips just offshore. The best place to spot them is Cathedral Rocks viewing platform, where you can safely observe the colony from above. Bring binoculars for a closer look, especially during early mornings when they’re most active.

Whale watching on Rottnest Island

From September to late November, the island becomes a front-row seat to the great whale migration, when humpback and southern right whales travel south with their calves after breeding in warmer northern waters. Rottnest’s sheltered bays serve as calm resting spots for migrating whales, especially mothers and calves. It’s common to see breaching, tail slapping, and fin waving close to shore, often just beyond the breakers.

Best viewing spots

Head to Cape Vlamingh and the West End Boardwalk for the best panoramic ocean views and close-up whale sightings. Cathedral Rocks and Bathurst Lighthouse are also excellent vantage points where whales often pass remarkably close to the cliffs.

Photography tip: Bring binoculars or a zoom lens, and watch for water spouts on the horizon, they’re often the first sign a whale is surfacing. Early mornings or calm afternoons give you the best light for photos and less surface glare for spotting.

Southern Fur Seal

Where to find them: Rocky coastal areas and sea caves

These sleek, dark brown seals haul out at Cathedral Rocks on Rottnest’s western tip, where you can often spot them sunbathing or playfully diving off the rocks. They’re powerful swimmers and a delight to watch as they glide effortlessly through turquoise waters.

Bottlenose Dolphin

Where to find them: Waters offshore surrounding the island

Rottnest’s resident bottlenose dolphins are often seen near Salmon Bay and Parker Point, cutting through the clear shallows in lively pods. Their grey-blue sheen and playful leaps make them one of the island’s most joyful marine encounters.

Osprey

Where to find them: Coastal cliffs and wooded areas, especially near salt lakes

The island’s ospreys are striking raptors with brown-and-white plumage, often spotted nesting atop high cliffs or manmade towers near Fish Hook Bay. Watching them swoop dramatically over the coast to snatch fish from the sea is a classic Rottnest sight.

Pied Cormorant

Where to find them: Along rocky shores and estuaries

With glossy black-and-white plumage and a distinctive yellow beak, pied cormorants can be seen perched on rocky outcrops or jetties, wings outstretched to dry after diving for fish in Rottnest’s coastal shallows.

Fairy Tern

Where to find them: Sandy beaches and coastal dunes

Australia’s smallest tern, the dainty fairy tern nests along Rottnest’s sandy beaches in summer. With pale silver feathers and a yellow bill, they’re a rare and protected sight — often seen darting gracefully over calm bays hunting for fish.

Dugite (snake)

Where to find them: Scrub and heathlands across the island

The dugite is Rottnest Island’s only snake species, slender and olive-brown in colour. Though venomous, it’s shy and avoids humans, often glimpsed basking quietly along walking trails or among coastal scrub. They play an important role in controlling rodent populations.

Spinifex Skink 

Where to find them: Sandy dunes and scrub vegetation

These golden-brown, spiny-scaled lizards are often seen basking on Rottnest’s limestone rocks. Masters of camouflage, spinifex skinks scurry quickly into crevices when disturbed and are a delight to spot along the island’s sandy trails.

White-striped Free-tailed Bat

Where to find them: Forested areas and caves

Rottnest’s only native land mammal, this small insect-eating bat is known for its distinctive white stripe along each side. It emerges at dusk, flitting above dunes and lakes hunting mosquitoes and moths.

Banjo Frog (Pobblebonk) 

Where to find them: Wetlands and freshwater bodies on the island

Named after its comical ‘bonk’ call that sounds like a plucked banjo string, this burrowing frog appears after rainfall around Rottnest’s freshwater lakes. Its glossy olive skin and musical chorus make it a quirky island character.

Frequently asked questions about Rottnest Island wildlife

Is it easy to see wildlife on Rottnest Island without joining a tour?

Yes. Many animals actually. Quokkas, osprey, cormorants, and dolphins are commonly seen around beaches, walk trails, and settlement areas. However, sea lions, whales, and fur seals are more reliably spotted on guided tours or at specific lookout points.

What’s the best time of day for wildlife spotting on Rottnest Island?

Early morning and late afternoon are ideal. Birds hunt more actively, marine animals come closer to shore in calmer light, and quokkas move around before the heat sets in.

Are there any areas of the island with restricted access for wildlife protection?

Yes. Certain dunes, nesting zones, and osprey platforms are fenced off or marked with signs, particularly during breeding seasons. You should stay on designated paths to avoid disturbing habitats.

Can I see wildlife while snorkelling, and where should I go?

Absolutely. Little Salmon Bay, Parker Point, and The Basin are the go-to options for spotting fish, rays, sea cucumbers, and occasionally sea lions.

What should I do if I encounter injured wildlife on Rottnest Island?

Do not touch the animal. Report it immediately to Rottnest Island Rangers via the visitor centre or emergency island number. Rangers are trained to safely handle injured or distressed wildlife.

Are there any safety precautions when encountering snakes like the dugite?

Dugites are shy and avoid humans, but you should give them space, stay on marked walking tracks, and avoid stepping through long grass. If you see one, stay still or slowly back away. Never attempt to handle it.
