Since its inception, motocross participation numbers continued to grow across Australia with competition numbers probably peaking in the 1970s and 1980s.

Because numbers were so high in the seventies, State riders were divided into two classes – experts and non-experts – with two separate meetings held on weekends. It was not uncommon for over 100 competitors to start the final feature races, with multiple rows on the start-line.

Australian fans got a taste of International Motocross in the late 1960s, early 1970s, when Australian-born pioneer of motocross Tim Gibbes ran the Australian New Zealand International Motocross Series.

But in the nineties, Australia got to host several World Championship events.

In 1992, the World Motocross des Nations teams event was held at Manjimup in Western Australia.

This was the first time ever that the event had been staged outside of Europe.

Due to its success, Australia won the rights to host a World 125cc Motocross Grand Prix at the same venue the following year.

Then in 2000, a round of the World 500cc Championship was held at Broadford in Victoria.
Like Manjimup, this was a big success and Broadford got to host a round of the 125/250/500 World Championships in 2001.

That year the FIM changed the Grand Prix format with all classes being held at the same rounds.
