15. Malcolm Oastler

One of Australia’s greatest off-track motorsport exports, Malcolm Oastler headed to England in the 1980s with the goal of making it as a race driver but ended up with a career that took him to the peak of world motorsport. As a designer and engineer he helped turn Reynard into the dominators of IndyCar racing in America and worked in Formula 1 with BAR and Jaguar, but nowadays has returned to grass roots racing back home, as Shannons Legends of Motorsport discovered.
