The Australian Solo Championship is a motorcycle speedway championship held each year to determine the Australian national champion. It is organised by Motorcycling Australia (MA) and is the oldest continuously running national speedway championship in the world having been run since 1926 with the exception of 1942-1945 when racing was suspended during World War II and 1955-1961 when the championship was not held.
The first Australian Solo Championship in 1926 was held at the Newcastle Showground in Newcastle. It was won by American rider Cecil Brown from Mick Brennan and Roy Hindle.
Legendary Danish rider Ole Olsen (1976) and Australia's own Jason Crump (2007) are the only riders who have won the championship while being the reigning Speedway World Champion. Olsen's controversial win at the Liverpool Speedway in Sydney in 1976 was the last win by a non-Australian rider. His win was controversial as many of the riders at the meeting protested his eligibility because of his nationality. However, with Olsen available to ride the promoters of the speedway insisted on his inclusion knowing that he would draw a larger crowd.
The current (2017) Australian Champion is Newcastle based Sam Masters.
The 2017 championship was held over four rounds in January. The rounds were held at the Adelaide's Gillman Speedway on 4 January, Olympic Park Speedway in Mildura on 7 January, Undera Park in Undera on 11 January and Loxford Park Speedway in Kurri Kurri on 14 January.
The winner of the Australian Solo Championship receives the Billy Sanders Memorial Trophy.
