In Australia, elected members of the parliament do not govern the country or any state. A small group of people, unelected in state or federal elections, control the relevant party and decide public policy.
It is indisputable that Queensland is not a democratic state by definition. The legislature does not govern the state. Unelected officials of either the Australian Labor Party (Queensland Branch) or the Liberal National Party of Queensland govern the state of Queensland. Elected representatives do not represent their electorates as they are mandated to represent the interests of their party.
Furthermore, Queensland does not have a separation of powers as members of the legislature serve in the government, and the legislature does not have an upper house.
