Have to say I have just spent a very enjoyable week in Hobart. For AFL it is a challenge because the small population is split between Hobart in the South and Launceston etc in the North . neither are big enough to support team and they are to distant to be treated as one. The interest is great generally.
sad to say but once GWS are established I think even Canberra would be more viable as it is the capital of the Riverina. (Unofficially)
Economically alone, the AFL would have to look at WA for a third team given population projections as a first step.
This sort of expansion for what gain mentality has zip to do with the a team in Tas other than to take the discussion off on some tangent, see the mind numbing use of population as a measure.
