The 2006 Commonwealth Games, officially the XVIII Commonwealth Games and commonly known as Melbourne 2006, was an international multi-sport event for members of the Commonwealth held in Melbourne, Australia between 15 and 26 March 2006. It was the fourth time Australia had hosted the Commonwealth Games. It was also 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 1956 Summer Olympics, officially known as the Games of the XVI Olympiad, were an international multi-sport event held in Melbourne, Victoria, Australia, from 22 November to 8 December 1956, with the exception of the equestrian events, which were held in Stockholm, Sweden, in June 1956.
