Much as I'd hate to see Monorail go, if a skyway was brought in as the substitute, can they please do a continuous load rather than pulsed? (a la disney world \ sentosa island cablecars) Capacity on the old one was dreadful, and the stoppages of the rope for loading and unloading (especially at (Australian \ Village operations speed) just kills any chance of the attractions success.
Side note on the affordability here - $3M USD is around $4.5M today. As we've learned previously from @Mark Shaw, the ride purchase cost tends to be about half the total cost of the project - so this is likely around $9M AUD - potentially with the extension to SWR adding a good chunk of that on top... so call it $15M? sounds like a good park addition to me.
One thing i've experienced on cable car \ big wheel attractions around the world are onboard dining experiences. While the ropeway is relatively short, one could offer multiple circuits in a premium car for VIPs, with dining or beverages offered would be a good revenue generating add-on too - something i'd happily pay to experience at least once - and being connected to SWR makes catering that easy with access to Shoreline and Hatsuhana kitchens to provide a unique tailored menu!
Below is one of the Mount Faber cable car ropeways to Sentosa Island in Singapore - just one example of what such an experience could look like!
