As Leadsled says (we are on the same page brutha) the ONLY reason it aint happening is because the turds in Canberra haven't figured out a way of charging for it. Good ole Australian user pays! If a politicians wife, son or daughter (or mistress, gay lover etc) is killed through it not being switched on, rest assured it will be switched on the day after.
There is already a government funded network in place, however I do not think it is aviation grade. Geoscience Australia is the federal government organisation responsible for managing the Australian geospatial infrastructure. The network is already used for marine, land, and airborne applications.
