As a personal rule, I would not fly an RA standard aircraft near or through a Designated Remote Area, because the engine failures are much more common, but the landings routine if you don't fly over the RA "Tiger Country".
I would not hire a basic GA aircraft such as a 172 or Cherokee 140 or Warrior through a DRA because, in the more unlikely event of an engine out, the radio equipment would usually not be good enough to get help.
A woman who lived on a Station near Cameron's corner decided one hot day that she would take the children in to the store at Moomba Gas field for an ice cream one day. The trip was only 20 to 30 minutes so she didn't bother to take any water. On the way in the Land Rover broke down/got bogged on a sand hill. The husband found the bodies later that day. I didn't check but I don't think that's a DRA. It just shows how little time things go bad in the outback if you're not covering the bases.
I would hire an aircraft with the additional $10,000 or so worth of aviation standard HF radio. Which is probably why this has been the first DRA discussion I can ever remember.
DRAs are not just in the outback, but can be in our Alpine areas. You won't necessarily identify one just by looking at a normal terrain map.
