A keen motorsport enthusiast and driver from a young age, he earned a first class honours degree in mechanical engineering from the New South Wales University of Technology.

[1] Deciding to try his luck in the European motorsport scene, Oastler relocated to England in 1985, but without any real financial back found it very tough to campaign in any series there.

He was working as a mechanic for Milldent Motorsport in Leicestershire in exchange for part-time drives in British Formula Ford 2000.

His Reynard 95I chassis went on to win eight races in total, including the Indy 500 and started from pole position no less than thirteen times.

Oastler also shares his various quirky engineering adventures through a YouTube channel, regularly featuring him working in his best thongs.
