Ole Olsen won the Danish Championship each year from 1967-1973, and won the Nordic Championship in 1971, 1973, 1974, 1976, 1977, and 1978. He also won the InterContinental Final in 1978 and was the British-Nordic-American Champion in 1974. In 1976 he won the Australian Championship at the Liverpool Speedway in Sydney despite protests from other riders who did not believe he should have been allowed to ride as he was not Australian (however, the promoters saw his drawing power and included him in the field). Olsen defeated Australian legends Phil Crump and home town hero Billy Sanders to take the title. In Australia he also won the NSW State Championship in 1972, and in the same year finished second in the Australian Championship behind Jim Airey at the Rowley Park Speedway in Adelaide.
