Billabong

A billabong is a type of water body found in Australia, typically forming as a secondary channel of a river that has become disconnected from the main flow. During floods, a river overflows and creates a loop or oxbow, which eventually dries up, leaving behind a stagnant pond. These waterholes are important ecosystems, providing habitat for wildlife and a water source in arid regions. The term is also popular as a brand name for surfwear, reflecting the Australian coastal lifestyle.
