@TBoyI may be totally wrong, but from the looks of it the purple track seems to be a piece of the coasters lift hill section.

Just putting it out there, while likely not at any summer carnivals across Australia, I did see and rode a transportable roller coaster called shark coaster at the Ekka (A Brisbane event during early August) last year. It was in the style of a wacky worm (Similar to bug run). So I wonder if any of you have seen it appear across the country since or before then, as I had never heard of it before.
