What does billabong mean?
A billabong is an Australian English word for a stagnant backwater — a section of a river that has been cut off from the main flow, often forming a small lake or pool of standing water. Billabongs typically arise when rivers shift course across flat floodplains, leaving behind curved channels that may hold water year-round or dry out in times of drought. The word comes from an Indigenous Australian language of the Wiradjuri family, built on the root 'bila', meaning river, and entered English during the nineteenth century through colonial contact. It occupies a cherished place in Australian culture, most famously as the setting where the swagman camps in the folk song 'Waltzing Matilda'. Beyond its literal geographic sense, billabong evokes images of the outback, gum trees reflected in still water, and a distinctly Australian way of life.
A stagnant backwater or side channel of a river, cut off from the main flow, especially in Australia.
"Pelicans gathered at the billabong as the sun went down."
Strongly associated with Australian English and outback imagery.
More broadly, any small lake or pool of standing water, particularly one left by a drying river channel.
"In the dry season, cattle crowded around the last remaining billabong."
Standard plural formation; used when referring to multiple such water bodies across the landscape.
"The floodplain is dotted with billabongs that fill after seasonal rains."
It's the very first place 'Waltzing Matilda' takes us — a jolly swagman camping by a billabong made this word famous far beyond Australia.

Etymology of billabong
The word billabong derives from the Wiradjuri language of Aboriginal Australia, spoken in New South Wales, combining 'bila', meaning river, with a suffix indicating continuation or branching — effectively 'a river running on into a dead end'. It was adopted into Australian English during the nineteenth century as European settlers described the waterways of inland Australia. The word gained international recognition through Banjo Paterson's 1895 ballad 'Waltzing Matilda', which opens at a billabong.
How billabong is actually used
The word is distinctly Australian and carries strong associations with the outback, bush poetry, and national identity. It appears rarely outside Australian contexts except in discussions of Australian culture or geography.
