Sandgroupers = West Australians, because the state is a desert, all sand.
Croweaters = South Australians, because the state flag has crows on it.
Banana benders = Queenslanders, because the banans grow straight in QLD and someone has to bend them so they can sell them to the southern states.
New South Welshmen = From New South Wales, because enyone who lives their is about as interesting the the name.
Mexicans = Victorians, because they are South of the border.
Tasmanians = 2 heads and 2 rows of teeth, because they are all inbreed.
Territorians or Troy Dans = Northern Territory, because Troy is a TV personality who is commonly known as a #ock %ucking Cow Boy, he even has a Drink named after him and we have an all girl Counrty and Western band up here called the "Toe Sucking Cow Girls".
Also most people think we all sound the same, but our speach is different in each state, not as much as the US, more like the differences in France, subtle, but different.
