I can answer this one.
The place was called Mirage Grand Prix Oxley
They had a 1100m track that had some of the fastest hire cars in Australia race on them.
They also had a smaller track t hat had smaller cars and a steelrail track that the cars drove around.
they also had a 18 hole mini golf course, a bumper boat pool and the waterslide.
What to know anything else I can help you as i worked there for about 12months in 1988.
Was a fun time.
