Yes, Billabong is an Australian surf brand stolen by Americans. the origin is sometimes referred to a river in Australia. The Americanized origin refers to the stereotypical pothead surfers. Urban myth is Billabong used to be Build-A-Bong but it soon changed.
Dude, that Billabong shirt is tight. Let's go smoke a bong while we're at it.

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.
