Where did you get "disused airbase" from??
Learmonth airport is used on a regular basis by the RAAF and international forces during exercises and it's allso used every day by Skywest and Qantaslink. They also fly out to Christmas Island from Learmonth. This is the airfield that services Exmouth for it's tourism and is the Southern Hemisphere landing field for the space shuttle in the event it has to land "Down Under"
So I have no idea where you get "disused airfield" from.
And I know this because I used to fly into Learmonth about twice a week.
