I don't get this.
If the proposal is to redevelop the whole port complex then it's not a cruise terminal, it's a port redevelopment and I would agree that Gov't funding should be involved.
If it's a cruise terminal then, like the SPCo linkspan, it's just an add-on part of the overall port which can be owned by and exclusively used by its private owners without Gov't funding.
Which is it? The addition of a cruise berth capability to our existing port, or redevelopment of the whole port? If the proposal is for the latter I have missed that emphasis in the reporting. If it is the former then I don't see any basis for the claim that the operator would want or be justified in wanting control of the revenues and operations of the rest of the port - their interest would be limited to the operations and revenues of the deep-water berth / cruise terminal.
