If it makes you feel better, I recently spent 18 months going around Australia driving as much "remote wilderness" in a big 4x4 as I possibly could. I explored all the corners of Tasmania, Goog's Track, The Flinders, Big & Little Desert, crossed the Simpson Desert on the Madigan line, explored Fraser Island, drove the old Telegraph Track, The Finke River Gorge the Gibb River Road and topped it off with the Canning Stock Route - 1,600 kms without seeing another person or vehicle on the track. It was epic.

Australia still has A LOT of wild places to explore.

Here's a small highlight reel of the drone footage from each state - https://www.youtube.com/watch?v=bmmbpjMgFqY
