Neither is really feasible without fulltime oval sport tenants.
In my opinion, that is one of the more significant reasons why the Government has been delaying building the new rectangular stadium for as long as possible. They're trying to drag things out in the hope that Canberra gets an AFL and/or BBL license so they can justify one "multipurpose stadium" to the normies, instead of having to build and maintain two purpose built stadiums.
There's also a bad strain that runs through the government of wanting to build Canberra in the image of other cities, namely Melbourne ATM, instead of simply allowing the city to develop into it's own thing.
Canberra's high rate of transience doesn't help either. Shit tons of expats come to Canberra, but most of them don't actually care for Canberra or the Canberran community, so they push for what benefits themselves instead of what benefits the community as a whole.
This is where V'Landys needs to earn his pay and reputation and turn the Civic Rectangular Stadium dream into a reality. Sure he is doing a good job with the Sydney Stadium policy, but Canberra needs to be shored up and won too. He shouldn't be myopic and let AFL eat away at our other regions. We need to stop the AFL encroachment and a league friendly city indoor stadium will guarantee it. If the AFL win and get an all purpose stadium then there popularity will simply continue to grow, while the Raiders/NRL will stagnate.
People will not go to oval shaped stadiums to watch rectangular sports with the same fervor as they do say at Parra's new stadium. After the initial bump in crowds there will be a drop off as we have seen at every other multi purpose stadium. Parra's and NQ stadiums have shown what people want and what will be successful. The Olympic stadium showed us all what won't.
Also he has done nothing to reverse the Adelaide City indoor stadium back to being Rectangular Football sports compliant like its original plan was to be. It will go down as one of them most massive lost opportunities RL has let slip through its fingers again and there have been some whoppers. Sure officially it was a decision made for budget savings, but do we honestly think that the AFL would accepted that decision quietly without working tiressly behind the scenes and or publicly(apply pressure when needed) to reverse it back to be AFL compliant.
I still have a sneaky suspicion that they had some kind of influence in making sure that no rectangular sport be able to use such a magnificent indoor stadium complex right in the heart of the city. They know that it would have been a game changer and a RL team playing there would have sellout crowds and hype like no other team has been able to generate in a AFL city before. Such a loss for our code and it's future success will never happen now in the city of Adelaide. Which is exactly what the AFL wanted.
And now they are continuing with their scuttlebutt down in Canberra. All Hail Andrew Barr, Dark Regent of the AFL.
