As of 2018, which country has the record of hosting maximum number of the Commonwealth Games (CWG)?

The Commonwealth Games (CWG) are an international multi-sport event involving athletes from the Commonwealth of Nations (a political association of 54 member states, almost all of which are former territories of the British Empire). The event was first held in 1930, and has taken place every four years since then. It is the world's first multi-sport event which inducted equal number of women's and men's medal events and was implemented recently in the 2018 Commonwealth Games held at Gold Coast, Queensland, Australia. The next Commonwealth Games, 2022 CWG, are due to be held in Birmingham, England from 28 July to 8 August, 2022.

Australia has hosted the Commonwealth Games five times (1938, 1962, 1982, 2006 and 2018); this is more times than any other nation. Two cities have hosted Commonwealth Games more than once: Auckland (1950, 1990) and Edinburgh (1970, 1986). Only six nations have participated in every Commonwealth Games: Australia, Canada, England, New Zealand, Scotland and Wales. Of these six, Australia, England, Canada and New Zealand have each won at least one gold medal in every Games. Australia has been the highest achieving team for thirteen editions of the Games, England for seven, and Canada for one. These three teams also top the all-time Commonwealth Games medal table in that order.
