Bunyip

Also known as Mulyawonk (Ngarrindjeri), Kine pratie, Wawi / Waawii (Wiradjuri), Bahnyip

Billabongs, swamps and rivers of south-eastern AustraliaFIRST REPORTED: Pre-colonialLAKE & SEA MONSTERS

The water spirit of Aboriginal tradition said to lurk in billabongs and swamps – turned by colonial newspapers into Australia’s first great monster story.

The bunyip is the creature lurking at the bottom of the billabong: a powerful being of swamps, lagoons, creeks and rivers, heard booming in the night and blamed for people who strayed too close to dark water. It is one of the oldest and most widespread of Australia’s legendary beings, and almost every Australian child grows up knowing its name. But “the bunyip” is really two stories layered on top of each other – an Aboriginal tradition reaching back thousands of years, and a colonial-era newspaper sensation that began in the 1840s.

The word itself comes from the Wemba-Wemba or Wergaia languages of north-western Victoria, and Aboriginal nations across the south-east have their own water beings with their own names and meanings. To the Ngarrindjeri of the lower Murray and Coorong, the mulyawonk is a half-man, half-fish creature – a greedy man who took more fish than he needed and was transformed, so that he now guards the river and its fish. Wiradjuri people of the Riverina tell of water spirits called waawii, and many communities used such stories to keep children safe around deep, muddy water. Historian Robert Holden identified at least nine regional variants. These remain living traditions, carrying lessons about country, sharing and danger, rather than simple descriptions of an animal.

European interest began with bones. On 2 July 1845 the Geelong Advertiser reported fossil remains found near Geelong under the headline “Wonderful Discovery of a new Animal”, explaining that a local Wadawurrung man had identified a bone as belonging to a bunyip – a creature combining, as the paper put it, the features of a bird and an alligator. The article is the earliest known printed use of the word, and it opened the floodgates. In 1846 a strange skull found on the Murrumbidgee near Balranald went on show at the Australian Museum in Sydney and drew crowds, until naturalists, including William Sharp Macleay, concluded it was the deformed skull of a foal or calf.

Reports multiplied through the 1840s and 1850s. In 1852 the memoir of William Buckley – the escaped convict who lived for more than thirty years with the Wadawurrung people – described a bunyip in Lake Modewarre and the Barwon River, with a grey, feathery-looking back the size of a large calf. Settlers reported bunyips in lagoons across Victoria and New South Wales; a carcass found at Brungle Creek near Tumut in 1883 caused brief excitement before disappearing from the record. By the 1850s “bunyip” had also become slang for a sham: in 1853 the orator Daniel Deniehy mocked a plan for a colonial hereditary peerage as a “bunyip aristocracy”, a phrase still used in Australian politics.

In the twentieth century the bunyip moved from the newspaper columns to the nursery, starring in picture books, cartoons and songs, and becoming a symbol of a uniquely Australian imagination. Scientists and historians have offered many explanations – stray seals swimming up the Murray, the booming call of the Australasian bittern, folk memories of extinct megafauna such as Diprotodon – but none fully captures a figure that means different things to different communities. The bunyip endures as both a cherished folk monster and a reminder that Australia’s landscapes were storied long before colonists arrived.

Type: Lake & sea monster
Status: Folklore
First reported: Pre-colonial
Best-known location: Billabongs, swamps and rivers of south-eastern Australia
Also called: Mulyawonk (Ngarrindjeri), Kine pratie, Wawi / Waawii (Wiradjuri), Bahnyip
Reported in: Australia

What witnesses describe

Descriptions vary enormously. Some accounts describe a dog- or seal-like animal with a round head, flippers and dark fur; others a long-necked creature with a small head, a mane or a horse-like tail; the 1845 Geelong account gave it an emu-like head, a large body and long claws. Many reports focus on its sound – a deep booming or bellowing from the reeds at night.

Where and when it’s seen

Billabongs, swamps, waterholes, lagoons and slow rivers, especially in the Murray–Darling basin, western and southern Victoria and the Riverina. Encounters are typically set at night or in the reeds at the water’s edge.

Notable sightings

July 2, 1845“Wonderful Discovery of a new Animal” Geelong, Victoria
The Geelong Advertiser reported fossil bones found near Geelong and recorded a Wadawurrung man’s identification of them as a bunyip’s, along with stories of the creature’s attacks. It is the earliest known printed use of the word.
1846–1847The Murrumbidgee skull Balranald, NSW, and the Australian Museum, Sydney
A malformed skull found on the bank of the Murrumbidgee was exhibited in Sydney as a bunyip skull and drew large crowds. Examination by naturalists showed it was the deformed skull of a domestic animal, probably a foal or calf.
1851The Challicum bunyip Fiery Creek, near Ararat, Victoria
A newspaper recorded an outline of a bunyip cut into the bank of Fiery Creek by Aboriginal people, who were said to have re-traced it regularly. The carving itself no longer survives.
1852William Buckley’s account Lake Modewarre and the Barwon River, Victoria
The published life story of William Buckley, who lived with the Wadawurrung for three decades, described bunyips in local lakes and rivers. He said he had only ever seen its grey back, never its head or tail.
September 1883The Brungle Creek carcass Near Tumut, NSW
Newspapers reported a large, short-haired headless carcass on the banks of Brungle Creek, compared to a seal as big as a bullock. The remains were said to be bound for a Sydney museum, but no record of their arrival survives.
January 29, 1972Murray Bridge’s mechanical bunyip Sturt Reserve, Murray Bridge, South Australia
South Australian Premier Don Dunstan opened a coin-operated bunyip that rose roaring from the river. Built by local businessman Dennis Newell, “Bertha” is still a beloved roadside attraction more than fifty years later.

What could explain it?

Seals: in 1933 geologist Charles Fenner suggested that seals occasionally swimming far up the Murray and Darling rivers could explain dog-headed, flippered bunyips.
Bird calls: the deep, booming call of the Australasian bittern – nicknamed the “bunyip bird” – may account for many night-time ‘bunyip’ noises from reedbeds.
Megafauna memory: since the 1870s some writers have proposed that fossil bones of extinct marsupials such as Diprotodon, or even folk memories of living megafauna, helped shape the stories.
Misidentified animals: platypuses, swimming dogs, large fish, floating logs and the strange skulls of deformed livestock all fuelled colonial-era reports.
Cultural function: in Aboriginal traditions, bunyip-type beings teach respect for water, sharing of resources and child safety – they are not necessarily meant as descriptions of a physical animal.

Legend, culture and tourism

The bunyip is part of the living knowledge of many Aboriginal nations, including the Ngarrindjeri mulyawonk story that is still shared on the lower Murray. In settler culture it became a national icon: a Gawler newspaper took the name The Bunyip in 1863; Michael Salmon’s picture-book character Alexander Bunyip first appeared in 1972; the phrase “bunyip aristocracy” has been used in Australian politics since 1853; and towns from Murray Bridge to Mulgildie (Queensland) have bunyip statues. There is even a town called Bunyip in Gippsland, Victoria.
