Umm, Qantas paid for it, assisted by a one-off payment by the Govt of $14M, who stated they hope to gain over $30M per annum for the deal. Sounds like a pretty good deal to me if the costs and returns are accurate.
PER airport did not contribute one cent, as far as I know, and are now acting like 3yo children with an iPhone.
If I had an idle $14M that I could invest for an annual $30M return, I surely would, unless I didn’t trust the projections.
So what do we have here? A private monopoly airport holding a private airline to ransom? Pretty much. But if you want a return from the WA Govt money that was put into this, what is the desired outcome?
