Make sure you have a 50 year lease signed before you start building. The Armidale Aeroclub put a lot of time and effort in building and maintaining a clubhouse. The rent went from peppercorn rent to $1000 a year then before too long to $4000 a year, they were trying to question the last increase when the lease ran out. The council then threatened them with eviction for non payment. The airfield is run as a purely commercial enterprise to maximise income, community doesn't enter the equation. I haven't heard what the outcome is, it appears the council will evict them and rent the building out commercially.
The Mayor is a really decent bloke and also a member of the Aeroclub, hopefully he will be able to talk the council round to sense. As with most councils now they are run by the CEO not by the people.
