Andrew Barr says a revamped Canberra Stadium needs to be at least 30,000 seats to ensure the capital doesn't miss out on hosting future internationals.
The ACT Chief Minister adds that was the size needed to host Australia's national teams - his preference to bidding for games at big tournaments like world cups.
He said one of the reasons for that was to expand the current capacity to 30,000 - an increase of 5000 seats - which he said was a requirement to host Australia's national teams in the future.
