There is more info in "The Australian" but the bit that got my attention is
"The defection of the two Liberals means the majority of MPs do not support the stadium, a condition of Tasmania gaining the 19th AFL licence.
While most Tasmanians back the new team, many do not support the stadium, believing the cost – which the opposition parties say will exceed $1 billion – cannot be justified during crises in health, housing and cost-of-living."
I think it could be interesting watching this play out.
