There is time. A 30K stadium would be a 2.5 year build. So almost two years available for planning/funding.It'd be a bit of a tight fit to get Canberra ready in time. The ball would have to start moving pretty much straight away.
It should happen, but I doubt it will unfortunately.
Reading the 2019 infrastructure report, it suggests a 25K stadium would be difficult at Civic (so 30K unlikely there), and also that they would not rebuild or spend significant $$$ at Bruce unless the Commonwealth Govt sold them the land, and that due to better transport links and more space, that EPIC may be preferred. It lists a new stadium as a medium term project, stagint that the current stadium would be fit for purpose until the mid 2020s.
Anyone know if they ACT govt is planning to update this report?
