The largest flightless bird in Australia is the Southern Cassowary, a massive, dinosaur-like bird with black plumage, a vibrant blue and purple neck, and a bony helmet (casque), known for its powerful legs and sharp claws, inhabiting the rainforests of Far North Queensland. While the taller Emu is Australia's largest bird overall, the Cassowary is the heaviest native bird and a significant, prehistoric-looking resident of the tropics, playing a vital role in seed dispersal.
Cassowaries (Indonesian: kasuari; Biak: man suar 'bird strong'; Tok Pisin: muruk; Papuan: kasu weri 'horned head') are flightless birds of the genus Casuarius, in the order Casuariiformes.
The southern cassowary (Casuarius casuarius), also known as double-wattled cassowary, Australian cassowary, or two-wattled cassowary, is a large, flightless, mostly black bird, found in Indonesia, Papua New Guinea, and northeastern Australia.
The cassowary is a large, flightless bird most closely related to the emu. Although the emu is taller, the cassowary is the heaviest bird in Australia and the second heaviest in the world after its cousin, the ostrich. It is covered in dense, two-quilled black feathers that, from a distance, look like hair.
Australia's biggest flying bird depends on the metric: the Australian Pelican has the largest wingspan (up to 3m) and longest bill, making it visually impressive, while the Brolga (Crane) and Sarus Crane (Australian race) are among the tallest and heaviest, with the Sarus Crane possibly the world's tallest flying bird, found seasonally in Australia. The Wedge-tailed Eagle is Australia's largest flying raptor, and the Australian Bustard is the heaviest flying land bird.
The largest (both heaviest and tallest) flightless bird, which is also the largest living bird in general, is the common ostrich (2.7 m, 156 kg).
The emu is the tallest bird in Australia. It reaches up to 2 m/ 6.5 ft in hight and can run really fast, with speeds up to 50 kmh/ 31 mph. However, emus cannot fly, just like an ostrich.

Emus are large, flightless birds resembling and related to ostriches. They are native to Australia.
People have referred to the cassowary — a massive, flightless, emu-like creature — as the most dangerous bird in the world, owing to the fact it can seriously injure or kill a human or dog in an instant with its deadly claws.
Steve Irwin, perhaps one of the most famous animal conservationists, was rarely afraid of anything. He wrestled with crocodiles, one of the deadliest animals that kill the most humans annually, which often left him with broken bones. But there was one animal that he preferred to steer clear of: the cassowary.
Yes, you can eat cassowary, and it has been a traditional food source for Indigenous peoples in New Guinea and Australia for centuries, valued as a delicacy, though the meat is notoriously tough, requiring long cooking times, and the birds themselves are dangerous to hunt or raise, with their meat sometimes described as gamey.
Cassowaries cannot fly, but they are incredible jumpers and can launch themselves up to 7 feet off the ground!
Ostriches are the biggest members of the group of large, flightless birds called ratites, which lack a keel, which is the structure that attaches flight muscles in other birds. Ostriches, emus, cassowaries, kiwis and rheas are all ratites.

The kākāpō is a large green parrot with a distinctive owl-like face and a waddling gait. They cannot fly, but they climb well. Kākāpō are: nocturnal.
The cassowary is a stocky powerhouse. Its height is similar to the emu, but it is much heavier. While the emu might seem intimidating at 38-40kg, a cassowary's kick has twice that weight behind it. Weighing up to 80kg, a kick with the cassowary's sharp claws would end any fight.
If a cassowary approaches you: Remain calm. Face the cassowary—never turn your back. Slowly back away.
Mike Tyson in his prime would absolutely destroy any kangaroo . They aren't as big or as intimidating as you think. Only a very few species grow to be as large as a man but even then we're not talking about an average dude. We're talking about one of the strongest fighters to ever exist in his prime.
In a bloodlusted one on one, ostrich wins 7-8/10. Ostriches are, on average, around 100kg, 2m tall, and have a top speed of 70kph. Cassowaries, by contrast, average much smaller. They top out around 50kg, 1.8m tall, and have a top speed of 50kph.
A cassowary's kick force is formidable and potentially lethal, delivering bone-breaking power with the full weight of the heavy bird, augmented by a 5-inch dagger-like claw that can disembowel attackers, making them one of the world's most dangerous birds, capable of causing severe, life-threatening injuries to humans and predators.
The bird that goes "woop woop woop" in Australia is the Pheasant Coucal, a large, ground-dwelling cuckoo known for its distinctive, resonant, bubbling call that sounds like "oop-oop-oop-opp" or "whoop-whoop-whoop," often heard morning and night, and sometimes mistaken for rain.
1. Northern Cassowary. The northern cassowary, or single wattled cassowary, is often considered the deadliest bird on the planet, especially when protecting cassowary chicks. Over 150 attacks have been reported from the norther cassowary since 1900.
Australia hosts many endemic birds, including iconic species like the Emu, Laughing Kookaburra, Sulphur-crested Cockatoo, Galah, and Budgerigar, plus unique ones like the Lyrebird, Bowerbirds, and numerous specialized honeyeaters and fairy-wrens, with specific regions like Tasmania or Queensland having their own unique sets of endemic species.
With a wingspan reaching more than two metres, the Wedge-tailed Eagle is Australia's largest bird of prey and one of the biggest eagles in the world. Once on the wing, they soar with ease, circling at great heights to altitudes of 2000 m!
