The 2006 Commonwealth Games, officially the XVIII Commonwealth Games, were held in Melbourne, Victoria, Australia between 15 and 26 March 2006. It was the largest sporting event to be staged in Melbourne, eclipsing the 1956 Summer Olympics in terms of the number of teams competing, athletes competing, and events being held.

The site for the opening and closing ceremonies was the Melbourne Cricket Ground which was also used during Melbourne's 1956 Olympic Games. The mascot for the games was Karak, a red-tailed black cockatoo (a threatened species). For the first time in the history of the Games the Queen's Baton visited every single Commonwealth nation and territory taking part in the Games, a journey of 180,000 km (112,500 miles). The relay ended when the Governor of Victoria, and former Commonwealth Games medallist, John Landy delivered the baton to Her Majesty the Queen at the Melbourne Cricket Ground during the opening ceremony.

During the 1998 Games in Kuala Lumpur, Malaysia, two cities initially expressed interest in hosting the event; Melbourne and Wellington, New Zealand. Wellington withdrew its bid, citing the costs involved with matching the bid plan presented by Melbourne, which became the default host without members of the Federation going to vote.

Early concerns arose about the large cost of staging the Games, with projected costs likely to be over 1 billion Australian dollars and a high likelihood the Victorian taxpayer would have to cover the expense. The cost was described in some local media as excessive. National Party leader Peter Ryan said that the Labor government should win "gold (medal) for burning money" [3] However, not all of this money was wasted. The actual costs for hosting the games was 1.144 billion dollars & prior to the Games, accountants at KPMG were estimating that the gross income generated by this event could be as high as 1.5 billion dollars.
