One thing in particular that stood out in Melbourne is that the majority of Mexicans say, "I'm going to Queensland" when they actually mean, "I'm going to the Gold Coast". Is anyone able to explain to me why people call a city by the name of the state? What other sayings/terminology is unique to particular places around the country? If you've got others from around the world, let us know here too. In Qld, we call a slab a carton. I've noticed that everyone I've met from NSW call it a case. There's one example.
