Love 'em.
There used to be a track at Goulburn & pretty sure there is one in the ACT. The old Newcastle track was a good one.
Here is the schedule for this season's WSS tour. This gives an idea - not all tracks are on it - Sydney is a very notable omission. Motor racing politics.
There are plenty of other speedways, they may not all be capable of hosting sprintcars. Plenty of other classes though.
