For 25 years, music promoter Charles Touber brought world-class acts to Tasmania.

He lists the Foo Fighters, Ramones, Beastie Boys, Elton John, the Cranberries and Iggy Pop as some of his biggest achievements for the state.

But he has major concerns about the state government’s numbers underpinning the proposed Macquarie Point stadium in Hobart — a stadium the state government said would bring world-class acts to Tasmania.

Mr Touber told a parliamentary committee examining the stadium that the project was shaping as a “basket case”.
