There should only be one International "Hub" in Australia at Alice Springs. This would be run by The Pitinjarra Tribe and Taxpayers would foot the bill.
Internal travel is then via "spokes" from that "hub" which operate the Domestic Fleet. This also would provide a revenue stream for both The Pitinjarra Tribe, The ATO and CASA, all who desperately need the cash.
Sydney movements would reduce by one third, (or one fifth if we apply the same rules as we apply to The Australian Senate), and those States not pulling their share would have their GST funding reduced accordingly.
Minister Albo will be pleased with my input as it impacts favourably on his electorate, (which is all that matters to him.... Oh and fighting Tories), and the spider tracks will be clear for all to see thus removing the need for ADSB below FL290.
Seems pretty clear to me.
