The Mackerras federal election pendulum, 2006 (by Malcolm Mackerras) shows the state of the major political parties ahead of the 2007 Australian federal election. The table shows seats in the Australian House of Representatives arranged in the form of a Mackerras Pendulum based on their 2004 federal election two-party preferred result. Some seats in New South Wales and Queensland underwent a redistribution in 2006, their margins have been recalculated due to this.
