Here’s a fact for you Vinelander, so Ballarat manages to contribute 1.5% of its population per day to rail. To get to 1500 people per day at 1.5% of the population South Australia would need to build a station and line at EVERY LOCALE within 100km of Adelaide (yes even Marananga), not just one regional city. You contribute some tax to that, because I don’t intend to.I'm not sure where you thought of that strange theory.
Adelaide Metro (train) is already utilised by more than 1.5% of Adelaide's population on an average day. Approximately 15.6 million "journeys" a year. 15.6/365 = 42,739 "journeys" a day. Yeah, I know the data doesn't show if someone's making multiple trips and relies on a few assumptions. Assuming South Australia has around 1.4 million people, 1.5% is 21,000. Which would give 2 journeys a day, bringing you to the average daily journeys of ~42,000.
The South Australian Tourism Plan 2020 even identified that improving access by rail and public transport was important.
I found it funny that a private investor working on a plan for a tourist train, that would create jobs and add to tourism, is publicly derided by the Government for blocking job-creation. A small $4.8 million roundabout isn't going to create long-term employment for anyone.
