Your both right and both wrong. The airport is controlled by BHPB, or the joint venturers in terms of the indenture act. The airport is in the industrial area called Olympic Dam that is not part of the Roxby downs municipal area. Roxby downs is a municipality under the relevant SA local government legislation. People have free hold land in Roxby Downs, including me. However the joint venturers, BHPB are require to support the town/council until it reaches a size of 10,000 IIRC.
Anyway, it is a company charter that earns points/SC but it seems no awards. It also has an interesting history with Alliance operating the route under both DJ and QF - much speculation that senior management were with QF hence the change of codeshare partner (or whatever is the proper term). However, BHPB policy is that points/SC can't be earnt on the route for company tickets. Before Alliance it was with Kendall under DJ and Ansett. Hence, I've got to fly the route on 2 operating airlines and 3 airline codes.
