This has been many many years in the planning if you see when they originally bought the land, nothing to do with Trump.
As others have said it'll bring lots of jobs and other benefits, money well invested. Someone mentioned it being in the South, it was located based on maximum amount of people within a certain travel time. All 5 surrounding councils are on board and a very well planned and detailed local consultation was done and so the majority of locals are in favour.
Other similar projects seemed to be all about flashy artists pictures and grand statements. When I first saw the plans for this it was all about upgrading stations and adding a new road junction to handle the increased traffic straight from a main road. I think they've really done their homework.
