Legislative authority is exercised by the Queensland Parliament which uniquely for Australian states is unicameral, containing only one house, the Legislative Assembly. The Parliament was bicameral until 1922, when the Legislative Council was abolished by the Labor "suicide squad", so called because they were appointed for the purpose of voting to abolish their own offices. Bills receive royal assent from the Governor before being passed into law. The Parliament's seat is at Parliament House at Gardens Point in Brisbane's CBD. Members of the Legislative Assemby represent 93 electoral districts. Elections in Queensland are held at the end of each fixed four-year parliamentary term, and are determined by instant-runoff voting.
