Its the ETFE permanent clear roof, like Dunedin's stadium roof. But I think you knew that.As opposed to the only other AFL stadium in the world with a roof...Docklands? lol
But Adelaide is the model in terms of location and events.
Like Adelaide, it's the centrality, which is yet another issue that mitigates against Bellerive oval.





Replacing the scaffold stands at UTAS with permanent stands and improved amenities under the new stands with permanent facilities would cost $150million and improve the spectators experience significantly. 
The roofed stadium was very much part of the proposal put forward by the Tasmanian Government in 2022 to sweeten the deal as part of the submission, so if on cost grounds, the roof is omitted from the design and instead perhaps a larger capacity 30,000 seat arena with roofing only covering the seats is built for $400 million, would this satisfy the AFL requirements? Would Tasmania still get its AFL team?
It's an interesting question. It also begs the question of why a gold plated stadium is proposed for Hobart while UTAS arena will still only see comparatively modest upgrades, when the proposal is to split Tasmanian home games evenly between two cities?
That is the point.
In Victoria the State Government have made an art form out of building massive projects that each have blown out by tens of billion of dollars and not a hint of any accountability whatsoever from the people of Melbourne who keep re-electing them
Maybe Tasmanians think differently, or maybe they reward financial incompetence too. Time will tell.
