The circuits used during the 2.5 litre years remained relatively constant. In New Zealand, there was no variation – each of the four circuits used hosted a race each year.
In Australia though, there was a bit more variation. Longford did not host a round in 1969, and Surfers Paradise (not the street circuit) only featured once.
