Despite an extensive 2015 study concluding that the inland rail line would never make its money back, the department responsible now says the line will make back its cost, therefore justifying its funding being treated as an investment.

The government committed more than $8 billion in equity funding to the construction (by the Australian Rail Track Corporation, which owns or leases all interstate or regional rail lines) of a freight line from Melbourne through inland New South Wales to Toowoomba and then onward to south of Brisbane, where it will connect to the existing Brisbane line. In addition, more than $1 billion has been spent via grants by this and the previous Labor government on the line and the Australian Rail Track Corporation will spend an unspecified, borrowed sum to build it, bringing the total cost to more than $10 billion -- although Treasury has flagged that the project is at risk of a cost blowout.
