G'day, Jerr.
Interesting pix.
I did spend some time in western Queensland doing mineral exploration - a lot of it around the Channel Country, near the SA border.
We used C180s, PA34s and Bell 47s. A fascinating and starkly beautiful part of the world.
p.s. What kind of snakes do you have at 'Home Base'?
The Eastern Browns were our biggest problem - they seemed to like finding their way into aircraft (and anything else mechanical).
