The Australian Speedcar Championship is a dirt track motor racing championship held in Australia each year to determine the Australian national champion in midget car racing. The single championship meeting, run over two nights in either late January or early February, has been held each year since first being run at the Tracey's Speedway in Melbourne in 1935.
Over the years there have been at times more than one Australian Championship meeting held in Australia (and sometimes in the same city) due to being sanctioned by different governing bodies. There were also times during the 1950s and 1960s when several track promoters around the country staged meetings which they claimed were either an Australian Championship, or sometimes even a World Championship, usually in defiance of not being awarded the right to host the official championship.
While there have been drivers who have won more than one Australian Speedcar Championship, only three drivers have ever won both the national Speedcar championship and the Australian Sprintcar Championship. They are the George Tatnell from Sydney who won the Speedcar title in 1972-73, 1973–74 and 1976–77, plus the Sprintcar championship in 1987-88. Adelaide's Phil March won in his Nissan powered Speedcar in 1985-86, and also won the Sprintcar championship in 1998-99. The third driver was Sydney's Robbie Farr who won the 1997-98 Speedcar title and the 2003-04 Sprintcar championship.
Andy McGavin and Ray Revell from Sydney, and Adelaide's Harry Neale, with five championships each are the most successful drivers in the championships history (all won before 1964-65). Western Australia's Mike Figliomeni, Warrenne Ekins from Darwin and Adam Clarke from NSW have each won the event four times while five drivers have won the event three times. Eleven drivers from the United States have won the championship.
