The Inter Dominion Trotting Championship Grand Final was a race for trotters within the overall Inter Dominion series. The series is held each year, and is a harness racing competition for both trotters and pacers that has been contested since 1936 in Australia and New Zealand. The host of the series is rotated between the 6 harness racing states of Australia and the North and South Islands of New Zealand. However, in recent years the Trotting series has mainly been held in Victoria with other Australian states reluctant to host the series. It forms part of the overall Inter Dominion series for pacers and trotters. The rotation of the Championships was fixed annually at a meeting of the council, five years in advance. It is held in New Zealand once in each four years. The Championships are held once in each racing year at a time and venue approved by the council by the completion of the Championships in the preceding year. The Grand Circuit race is not held at the same time as the Championships. A meeting with leading Australasian harness racing officials led to a decision that the Inter Dominion Trotting Championship would be discontinued after 2012. Several new major trotting races have been created to replace the series, most notably the Great Southern Star at Melton in March, which was to be run with a one-day heat and final format. The Trotting Championship was re-introduced in 2018.
