JG3: Dunmarra Roadhouse south of Daly Waters in the NT has a strip behind the roadhouse with bowsers, food and accommodation (camping and motel units).
The owner flies a Murphy Rebel, at least did when I was there in 2018.
Also Sandfire Roadhouse on the 90 mile beach in WA. Strip is behind the roadhouse. it's a fair walk with jerrycans, but you can taxy up near to the bowsers along a track if you ask the staff.
I got bogged on the way back.
