That wasn’t the shuttle to mirage at port douglas was it?
You have a long memory Sunnie! That was a hovercraft operated in the days of Skase, who died in 2001. I think the hovercraft commuter operated briefly between Cairns airport and Port Douglass in the late 1980s?
I remember the WIGE (Wing in Ground Effect) "aircraft" undergoing trials in Cairns, thought it was more recent but looks like it was around 2003 or slightly later:
