If you check ASAs annual reports you will find they actually were paid
regional subsidies by the government to continue to provide ATC functions in regional areas that were loss making.
ASA actually manage some outstation towers in the USA.
ASA manages airspace for the Solomon Islands and Nauru under a commercial arrangement.
max1, ASA management carnt even work out how many ATCers they need to run Oz airspace ... they carnt even pay our ATCers properly - You expect anyone to listen to them about ADSB ?
