'Billabong' is an
Australian English word used to refer to an
oxbow lake, a stagnant pool of
water attached to a waterway. Billabongs are usually formed when the path of a
creek or
river changes, leaving the former branch with a dead end. The word is derived from two
Indigenous Australian words: "billa" meaning "creek" and "bong" meaning "dead".
Billabongs appear relatively often in
Australian literature. One of the most well-known references is in the opening line of
Banjo Paterson's famous
poem "
Waltzing Matilda".
