Can't see it happening (Cairns surviving). For those not aware Cairns is a beautiful place to visit, but really doesn't have anywhere near the population or economy to support even an NBL team.
120k people, and an economy driven mostly from Tourism, Sugar and Transport (of raw materials mostly), with Sugar and Tourism at fairly low levels. Previous irresponsible ownership has given the community and the rest of Australia the false sense that Cairns is sustainable enough for a franchise, due to him footing the bill and trying to buy Championships.
Now that the public ownership model is in place, there's still not enough (public interest and alternate revenue) to keep the team going. Whilst it will be a shame to lose the Taipans, it will reinforce the new market forces in the newNBL and these requires you to a.) ensure you have sufficient cash-flow, and b.) that you break even, make a small profit, or are prepared (ie. Funded) to take a small loss from operations.
You can't do that without either a major investor (Hawks), large crowds or a lower cost of operations (T'Ville). Yes they have a cheap roster, but I'm sure the low revenue and the venue hire are the killer lines on their P&L.
