“Australian raptor” is not the name of a single, well-documented cryptid. The phrase has been used online for two quite different ideas: a giant bird of prey soaring over the Outback, and a “raptor”-style predatory dinosaur, best known under the name Burrunjor, said to survive in the remote north. This entry looks at both, and at the real giant raptors that did once live in Australia.
| Type | Two different claims: a giant flying predator, and a surviving bipedal dinosaur (Burrunjor) |
|---|---|
| Region | Outback Australia; Burrunjor reports come mainly from the Northern Territory |
| Evidence | Anecdotal reports and reported tracks; no specimens, photographs or casts in the scientific record |
| Real giant raptor | Dynatoaetus gaffae, a Pleistocene eagle with a wingspan of about 3 m |
| Real dinosaur “raptors” | Megaraptorid theropods such as Australovenator, extinct for over 90 million years |
A note on this entry
An earlier version of this page described an “Australian Raptor” with a 20-foot wingspan, glowing eyes and possibly leathery pterosaur wings, said to come from Indigenous Australian traditions. We could not trace that description to any published sighting, folklore collection or Indigenous source, so it has been removed. What follows is what can actually be documented.
The giant eagle that really existed
Australia did once have an eagle far larger than any alive today. Dynatoaetus gaffae was described by Flinders University researchers from fossils found in Mairs Cave in the Flinders Ranges of South Australia, with further bones linked to sites including the Naracoorte and Wellington caves and the Lake Eyre Basin. It lived in the Pleistocene, had a wingspan of about three meters, roughly twice the size of today’s wedge-tailed eagle, and talons large enough to take young kangaroos and other megafauna. Its closest relatives are the Old World vultures and the Philippine eagle.[1][2]
Dynatoaetus lived alongside the wedge-tailed eagle and is now extinct. No living population survives, but its discovery shows that the image of a giant Australian bird of prey is not pure fantasy. It simply belongs to the Ice Age.
Australia’s lost birds of prey
Dynatoaetus gaffae turned out not to be alone. In November 2023, Ellen Mather, Trevor Worthy and colleagues at Flinders University described a second, smaller species, Dynatoaetus pachyosteus, from Victoria Cave at Naracoorte. It had a wingspan similar to a wedge-tailed eagle’s but much more robust legs. They also re-examined Cryptogyps lacertosus, Australia’s only known vulture, which was about the size of a wedge-tailed eagle.[5]
The timing matters for any “living giant raptor” claim. Both Dynatoaetus species lived between about 500,000 and 200,000 years ago. The vulture survived longer; dating of cave deposits shows it was still alive around 60,000 years ago, close to when people arrived in Australia. The researchers suggest that the disappearance of Australia’s large marsupials, the carcasses and prey these birds depended on, probably helped drive them to extinction. A giant eagle in today’s Outback would have nothing large enough to live on.[5]
The wedge-tailed eagle
The largest bird of prey in Australia today is the wedge-tailed eagle, with a wingspan that can exceed two meters. Wedge-tailed eagles soar high over open country, hunt rabbits, wallabies and young livestock, and are often seen feeding on roadkill. A large “wedgie” seen without anything to judge its size against is a likely source of giant-bird reports.
The Burrunjor: a “living dinosaur”
The other “Australian raptor” is the Burrunjor, a large bipedal reptile said to live in the remote Northern Territory, around Arnhem Land and the Roper and McArthur rivers. Popular accounts describe an animal 20 to 25 feet long that walks on its hind legs, has small clawed hands and kills cattle.[3][4] Commonly repeated stories include:[3][4]
- 1950s. Cattle ranchers reported livestock killed by a large predator and three-toed tracks made by an animal walking on two legs.
- 1957, McArthur River. About fifty cattle were said to have stampeded at night, with grunting heard, and partly eaten carcasses found the next day.
- 1978. During a search for a lost man in Arnhem Land, police and Aboriginal trackers reported hearing loud noises at night.
- 1985. A family traveling to the Roper River reported a large creature.
These accounts circulate mainly through cryptozoology books and websites, and we have not been able to trace them to original newspaper reports or official records. Claims that Aboriginal rock art and stories depict the Burrunjor are also repeated without specific sources, so they should be treated with caution.[3][4]
Where the Burrunjor stories come from
The Burrunjor reports can be traced mainly to two books. The Australian writer Rex Gilroy collected them in Mysterious Australia (1995), presenting them as Aboriginal traditions from Arnhem Land east across the Gulf of Carpentaria to Cape York, along with accounts from cattlemen. The British zoologist and cryptozoology writer Karl Shuker repeated the story in The Unexplained (1997). Most later websites draw, directly or indirectly, on these two books.[6]
The story has also been taken up by young-earth creationist writers, who cite it as evidence that dinosaurs and people lived together. Even one such article admits that Gilroy’s accounts need independent confirmation before they can be relied on, and that confirmation has never appeared. Several of the most dramatic details, such as a 1961 report of a reptile seven to eight meters tall near Lagoon Creek, come without any named original source.[6]
The real giant lizard
If any real animal lies behind Australian “dinosaur” stories, the best candidate is Megalania (Varanus priscus), a giant monitor lizard that lived during the Pleistocene. Size estimates have varied enormously. Early reconstructions suggested animals up to 7 meters long, but more careful studies of the bones suggest most individuals were a little over 2 meters from snout to vent, with large ones perhaps reaching 4.5 to 5.5 meters including the tail. The youngest remains that may belong to it, from Queensland, are about 50,000 years old, which means the first Aboriginal Australians may have met it. The paleontologist Ralph Molnar has suggested that such encounters could lie behind stories like the whowie, a monstrous lizard of southeastern Aboriginal tradition.[7]
Its living relative, the perentie (Varanus giganteus), is Australia’s largest living lizard, reaching about 2.5 meters. When threatened it can rear up on its hind legs in a defensive stance, and when startled it may even sprint a short distance on its hind legs. Seen suddenly in scrub, a big perentie standing upright is about as close to a small bipedal “dinosaur” as Australia gets today.[8]
Real dinosaurs and real explanations
- Megaraptorids. Australia did have large predatory dinosaurs. Australovenator, found near Winton in Queensland, was a lightly built theropod about six meters long that lived some 95 million years ago. Nothing suggests any survived to the present.
- Monitor lizards. Perenties and other large goannas can stand up on their hind legs, and the extinct giant monitor Megalania once lived in Australia. A goanna seen briefly standing upright is a plausible source of “dinosaur” reports.[3]
- Crocodiles, dingoes and wild dogs. These are the usual causes of livestock losses in northern Australia.
- Tall tales. Outback storytelling has a long tradition, and some reports may simply be good yarns.
For another reported flying giant, see the Ahool of Java, and for a reported surviving dinosaur in Africa, Mokele-Mbembe.

Correction note (October 2026): This entry was completely rewritten. The earlier version described an “Australian Raptor” with a 20-foot wingspan, glowing eyes and leathery pterosaur-like wings, attributed to Indigenous traditions and to a group of hikers.
