Does wet n wild Gold Coast do fast track early in the season. And if so how much per person is it. I just tried calling the my fun number and it was over a 55min wait.

Yes, both wet n wilds do fastpass.

Wet N Wild do it in the September holidays, the whole of December and January as well as the April holidays for certain. They may have it available on busy weekends leading up to the high season. Never used it myself so I have no idea about cost.
