The problem with Albion Park is corrosion. IRA is not Longreach where the air is dry. At IRA, if you scrape a hole in the ground it fills with saltwater and the runway is only a short distance from Lake Illawarra which opens to the sea.
So if OGA is seen as a significant heritage item, its not the place to go to preserve it. If its to be just a tourist draw card then its the way to go.
