Oh and i should revise those directions, the distances are way off, i almost gave up, i thought I'd gone past it.
1. The turn-off is almost 10km past AIR, not 3km, you just need to look out for the "4WD blah blah hire course" sign (summin like that).
2. It's at least another 5km down the seeled road, and there's no sign, you just keep going until there's no sealed road left then turn on to the right-hand dirt road.
3. Those with low cars and hard susp, take it real easy on the road to the office, HEAVILY rutted and pot-holed.
