Same thing exists in Tasmania on the overland track
And the three capes track.
Re: helicopters, On the overland everything gets helicoptered in and out including the waste from the toilets. I imagine heli pads will be installed in the high country to both service the huts and for rescue.
The guided walks using the private huts on the OLT seem to have no shortage of people shelling out $3500 p/p for five nights fully catered and only have to carry 9.5kg.
The three capes of $500 p/p for three nights? From memory....but carry your own food
