Sydney's Craig Boyce won his first Australian championship, defeating defending champion Glenn Doyle, with veteran Glyn Taylor finishing third (both from Perth). Boyce was unbeaten on the night, securing his first Australian Championship.[2]
It was the only time the Australian Solo Championship final has been held in the Northern Territory.[3]
Leigh Adams withdrew from the Australian Final after breaking his wrist in Adelaide on 9 January 1991. As the 3rd placed rider in the Victorian title, four time national champion Phil Crump was seeded to the Australian Final in Adams place.
After a number of high-profile riders had failed to qualify for the Australian final, a special qualifying round was held at Arunga Park the week before the finals. Unfortunately the round was not well attended after it was revealed that only the top five riders would be paid travel money, prompting many (mostly NSW rider Stephen Davies who had placed 2nd and 3rd in the previous two Australian titles) to boycott the event.
