Brisbane is the capital of the state of Queensland and also the third-largest city in Australia. One of the unique fact about Brisbane is central streets in Brisbane are named after members of the royal family (Adelaide, Alice, Ann, Charlotte, Elizabeth, Margaret, Mary). Brisbane is named after the river on which it sits. It was chosen as the capital when Queensland was proclaimed a separate colony from New South Wales in 1859. The Annual Brisbane Festival is the largest and most popular event in this city.
