Believe me I know this well. I was a member of the Taskforce - based on the Sunshine Coast from November 2001 immediately following the election and because of aviation background, involved with government discussions and consultations with industry.
You are right about runways and resorts - one of the first things I did was to get a flight in a C172 around the circuit. I lived in the Atlantis Apartments directly opposite Maroochy from November 2001 to March 2002.
I hated it.
