A former British colony in the southern hemisphere populated by the descendents of the criminal and dirtbag scum of Britain, who were deported there during the late 18th and 19th centuries. This land is now filled with dopey cockheads who think they're king shit but who are really just foul-mouthed dishonest drunken arrogant douchebagpieces of shit.
The word Cockstralia is a combination of cockhead and Australia. The people of this country are known as Cockstralians.
Did you see that guy Bruce and his ugly trollop girlfriend at the party last night? Every second word out of their mouths was "fuck" or "cunt" and they both got so drunk that they couldn't even walk and then vomited all over the back bedroom, the stupid assholes.
Yeah I saw them. What else did you expect from people from Cockstralia?
