Given the massive areas of most of these cattle stations, I'd guess that any surveillance would have to involve a much higher altitude machine than your average garden variety RC / autonomous type amateur device; in which case the wild west idea of "shootin' it down if its on me land" is a wild west fantasy at best.
What would they do if the libbos decided to fly a 172 around? Shoot it down maybe? I hear Jim-Bob is pretty sharp with a sling-shot.....
