Hi Maj
You have to keep an eye on these minority religious groups the next thing will be no flying on a Saturday.However they are extremely well organized ,well funded and very well connected. If you had asked around Cooranbong five to ten years ago will they subdivide the airfield and sell off the flying school the answer would have been a resounding No.
Most people think that it is just the housing but if you delve into it the zoning allows for a hospital or other health based business.This is not widely known even in the local SDA community (Those who lost jobs with the flying school were SDA)
So in years to come I would expect to see medium density housing,nursing homes,and maybe a training hospital all of which will generate a tidy (tax free ) income stream for what is supposed to be a not for profit organization.
