I once ferried an AS350 from Mackay in QLD through outback Australia to Adelaide SA and back again in a B3 via Gladstone, took just over ten hours flying each way, not much to look at except red dirt, the odd track, maybe a homested, oh and more red dirt. Still a good trip and nav was a challenge ( I did'nt feel comfortable sitting like a numpty and relying solely on the GPS)
Possibly not the smartest thing to admit to here-abouts, over country that most would regard as very easy to map read. Like there's one little creek that goes pretty much all the way.
