Hi Oz,
Yep! As JR says, its tempo and location specific until they get ATC up there - again.
As for DTI for the rest of OZ....too far gone now, IMHO.
All FS frequencies / outlets were either swapped over to ATC freqs, or dismantled. Hence we had a 'few' Flightwatch VHF's around the place, 3 in WA at one time - these were the ones superfluous to ATC req's.
Now they have g o r n e as well.
Keep safe,
