Australian Sea-lion

Scientific name: Neophoca cinerea
Status:
Endangered
Regions: Kangaroo Island, South Australia; Eyre Peninsula, South Australia; Shoalwater Islands Marine Park, Western Australia.

The Australian Sea-lion, known for its playful behavior and small external ears, is found around the southern coast of Australia, including Kangaroo Island, the Eyre Peninsula, and Shoalwater Islands Marine Park near Perth. These sea-lions breed every 17-18 months, with females returning to their birthplace to breed.

Australian Sea-lions primarily feed on sea floor creatures like octopus and rock lobster and typically live 17-25 years, reaching breeding maturity at 12. They are listed as Endangered due to threats such as accidental drownings in gillnets from commercial fisheries.

Experiences vary in different regions. Kangaroo Island offers the chance to walk on the beach within the colony, whereas the Eyre Peninsula and Shoalwater Islands Marine Park offer swimming/snorkelling experiences.

Southern Cassowary

Scientific name: Casuarius casuarius johnsonii
Status:
Endangered
Region: Daintree, Queensland

The Southern Cassowary is a striking and enigmatic bird, known for its vibrant blue and purple head, red wattles, and distinctive casque—a helmet-like structure on its head. While the exact function of this casque remains uncertain, recent research suggests it might help the cassowary detect low-frequency sounds, a sense shared with some dinosaurs and modern animals like elephants.

This flightless bird is notable for its unique feathers, which are long, glossy, and hair-like, with a quill that splits into two and lacks the usual barbules that hold feathers together. Cassowaries are solitary animals with a home range that can vary widely depending on food availability and breeding cycles.

Despite being a key figure in the Wet Tropics' ecosystem, where they help maintain rainforest diversity by dispersing large seeds, Southern Cassowaries are classified as Endangered in Queensland and Vulnerable by the IUCN. Their numbers are estimated at around 4,000 adults in Australia, and their habitat is increasingly fragmented by land clearing, roads, and other human activities.

Encounters with these impressive birds can be thrilling, but it is crucial to respect their space. Although sightings are not guaranteed, spending time in their habitat, especially with a guide, increases the chances of observing these remarkable birds.

Green Turtle

Scientific name: Chelonia mydas
Status:
Vulnerable (locally)
Region: Frankland Islands, Queensland; Exmouth (Ningaloo Reef), Western Australia.

The Green Turtle is one of the world's largest sea turtles, with an average length of 1.2 meters (4 feet) and a weight of 225 kilograms (500 pounds). It ranks second in size only to the Leatherback Turtle. Due to threats from hunting, pollution, and other human-related factors, the global population is classified as endangered, and vulnerable in Australia.

These turtles are herbivores, primarily feeding on seagrasses, algae, and other marine plant matter. Their sharp, serrated beak enables them to graze efficiently on seagrass beds and scrape algae from rocks. This gentle feeding method actually benefits the seagrass beds, as they selectively eat the top of the leaves without disturbing the roots, promoting healthy and fast-growing seagrass.

You can snorkel with Green Turtles at Ningaloo Reef in Western Australia and the Frankland Islands on the Great Barrier Reef. These areas offer excellent opportunities to observe these magnificent creatures in their natural habitats.

Pink Cockatoo

Scientific name: Lophochroa leadbeateri leadbeateri
Status:
Endangered
Region: Mungo National Park, New South Wales

The Pink Cockatoo is a striking bird, predominantly white with distinctive pink coloring on its head, neck, underbody, and wings. When its crest is raised, it reveals a vibrant red band with a yellow stripe, although it appears white when folded. This cockatoo thrives on a varied diet, including seeds from grasses and herbs, fruit, roots, bulbs, and insect larvae.

Primarily found in the inland regions of Australia, the Pink Cockatoo is commonly seen in dry woodlands and semi-arid areas, with Mungo National Park being a notable location for sightings. Despite its adaptability, the Pink Cockatoo's population has been adversely affected by habitat loss due to land clearing, which has diminished the availability of crucial nesting sites.

Blue Whale

Scientific name: Balaenoptera musculus
Status:
Endangered
Region: Dunsborough, Western Australia

Blue Whales, the largest animals on the planet, captivate with their sheer size and the mystery surrounding them. While previously thought to travel solo, recent observations have revealed that Blue Whales often move in pods, with groups of up to eight whales recorded.

In Western Australia's Geographe Bay (Dunsborough), where Blue Whales are commonly sighted from November to the end of the year, researchers monitor their behavior. They focus on pod dynamics, whale sizes, and the presence of calves. This data contributes to ongoing research efforts on whale populations in the region.

Christmas Island Hawk-Owl

Scientific name: Ninox natalis
Status:
Vulnerable
Region: Christmas Island

The Christmas Island Hawk-Owl, one of Australia's rarest raptors, is a striking bird known for its beautiful plumage and large yellow eyes. Measuring just 26 to 29 cm in height, this owl is roughly the size of a common pigeon but with a distinct barred breast. It has a unique boo-book call that often reveals its presence before it's seen. Endemic to Christmas Island in the Indian Ocean, this small nocturnal bird of prey inhabits various forest types across the island. It is most commonly found in primary forests, while post-mining regrowth areas are less frequented.

With a population of approximately 1,200 individuals, the Christmas Island Hawk-Owl is listed as vulnerable. Sadly, the total population has likely decreased by at least 25% since European settlement due to extensive deforestation on the island—about 25% of the island's forest has been cleared.

For the best chance to spot this elusive raptor, joining a local expert guide is recommended, as they are familiar with the bird's preferred haunts within the island's dense rainforests and coastal terraces.

Tasmanian Devil

Scientific name: Sarcophilus harrisii
Status:
Endangered
Region: TasmaniaMaria Island, Tasmania.

The Tasmanian Devil, Australia's largest carnivorous marsupial, is known for its robust build and distinctive scream. Once found across the Australian mainland, it disappeared due to predation by dingoes. Today, it primarily inhabits Tasmania, where it scavenges for food and occasionally hunts wallabies, possums, and wombats.

These nocturnal creatures are characterized by their strong jaws and a distinctive, spine-chilling scream. Their population has been severely impacted by Devil Facial Tumour Disease (DFTD), a transmissible cancer that has afflicted 90% of the population. Despite these challenges, conservation efforts have made significant strides.

Maria Island, located off the east coast of Tasmania, is a key site for the Tasmanian Devil's recovery. In 2012, fifteen Devils were introduced to the island as part of a rehabilitation program. The island's population has been steadily growing, free from the disease that plagues their mainland counterparts. Estimates suggest there are now close to 60 Tasmanian Devils on the island.

In addition to Maria Island, other areas in Tasmania also provide opportunities to see Tasmanian Devils, especially in regions where the disease has not yet spread. These efforts are crucial for preserving the species and ensuring its survival for future generations.

Kangaroo Island Short-beaked Echidna

Scientific name: Tachyglossus aculeatus multiaculeatus
Status:
Endangered
Region: Kangaroo Island, South Australia

The Short-beaked Echidna, one of the world's most ancient mammals, boasts a fascinating array of unique traits and behaviors that underscore its importance in Australia's ecological history. While this species is found across the continent, the Kangaroo Island sub-species is endangered, making its conservation a priority.

During feeding, the echidna uses its long, sticky tongue—capable of extending up to 18 cm from the tip of its snout—to lap up ants, termites, and other insects at a remarkable rate of over 100 flicks per minute. This rapid tongue movement is reflected in its scientific name, with "tachy" meaning fast and "glossus" meaning tongue.

Though sightings are not guaranteed, spending three days or more on Kangaroo Island with an experienced guide significantly increases the chances of encountering this elusive creature.

Regent Parrot

Scientific name: Polytelis anthopeplus monarchoides
Status:
Vulnerable
Region: Riverland, South Australia

The Regent Parrot is a striking bird with a slim build, long, tapering tail, and back-swept wings. Its vibrant yellow plumage contrasts with blue-black wings and tail, and it features a prominent yellow shoulder patch and red wing patches visible in flight. The bill is deep red or pink. Females and juveniles are duller, with olive-green feathers and less vivid wing markings. 

Feeding mainly on seeds from grasses, plants, and cereal crops like wheat, the Regent Parrot also consumes buds, flowers, insect larvae, psyllids, and lerps. It forages in pairs or small groups, usually on the ground but also in tree canopies or on spilled grain. Typically seen in pairs or small flocks, larger groups form around abundant food sources. During breeding season, males may form single-sex flocks while females incubate eggs.

The Regent Parrot is found across South Australia's Riverland region, particularly along the Murray River. However, the population has become fragmented and declined due to the clearance of large areas of both breeding and foraging habitats, leading to its classification as vulnerable.

Whale Shark

Scientific name: Rhincodon typus
Status:
Vulnerable
Region: Exmouth (Ningaloo Reef), Western Australia

The Whale Shark is the world's largest fish, reaching lengths of up to 12 metres and boasting mouths that can grow to 1.5 metres wide. Despite their massive size, Whale Sharks are harmless to humans and feed on plankton and small fish by filtering water through their gills.

Each autumn, the Ningaloo Marine Park experiences a spectacular mass spawning of coral, which occurs about seven to ten days after the full moon in March and April. This spawning event triggers an influx of krill and plankton, drawing Whale Sharks to the area in large numbers. During this time, Whale Sharks are often seen hanging vertically at the water's surface with their mouths open to capture the rich food supply.

From March to August, you can swim with Whale Sharks along the Ningaloo Reef in Western Australia. Contrary to what one might expect from such a large 'shark,' Whale Sharks are slow and leisurely swimmers, cruising at speeds of no more than 5 km per hour (3.1 miles per hour). Unfortunately, the global population of Whale Sharks has declined by more than 50% over the last 75 years, leading to their classification as Endangered.

Tasmanian Wedge-tailed Eagle

Scientific name: Aquila audax fleayi
Status:
Endangered
Region: TasmaniaMaria Island, Tasmania.

The Tasmanian Wedge-tailed Eagle is Australia's largest bird of prey, recognized for its distinctive wedge-shaped tail and impressive size. This subspecies, first identified in the 1950s, is notable for its pale plumage, which varies from buffy-white to golden or russet hues, and its larger size compared to mainland birds. The population of adult Tasmanian Wedge-tailed Eagles is estimated at fewer than 1,000 individuals.

Inhabiting a variety of habitats across Tasmania, including mature forests and offshore islands, these eagles are more commonly found on the east coast, such as Maria Island. They defend extensive territories and prey on reptiles, birds, and mammals.

Key threats to their survival include habitat loss, nest disturbance, collisions with artificial structures, electrocution, and persecution. Even minor disturbances, especially from people or helicopters, can significantly impact breeding success, potentially leading to nest abandonment. Conservation efforts focusing on protecting nests and reducing unnatural mortality rates are crucial for the species' future.
