In the US airports are generally owned by a city or municipal council and is provided as a community facility, not as a way of spinning money. It benefits the WHOLE town to have a good airport. In Australia some genius thought it would be a good idea to sell off all the airports and to run them as a private business as a result we get carparks factories and fast food outlets built overnight but things like ILS aerobridges and terminals are not built because they are to expensive.
If they are really going to build 32 ILS in OOL that would have to show how much the people who are running the airport know about aviation
