Contrary to what you might think, there actually is an origin to this clothing company's name. A billabong is an Australian name for a dead-end channel, or a stagnant pool.
for ignorant people such as ms. greene who think billabong is simply a company, it is an australian word meaning a stream or dead end channel that only has water when it rains.
The most widely sold "surf brand" in Australia, which is a complete rip off and has stolen the name of a small river in central Australia. Unfortunately considered cool until teenagers realise what "Gucci" and "Armani" are and bleed their parents dry, while talking on their mobile phones and eating fast food.
