One of the key features of the official concept design of the $715 million Macquarie Point stadium is a ‘big plastic roof’.

The roof would be an Australian first, and is a non-negotiable feature for the stadium imposed by the AFL in order to give Tasmania a license for a team in the national league.

Using timber support, the ethylene tetrafluoroethylene (ETFE) roofing has been likened to a giant “backyard shade sail”.
