I agree, it sounds like she was used to hearing his voice when he was talking to his radio chums and most probably didn't contact her personally. The fact that she was so quick to dismiss him as dead and is packing up his belongings tells me that their relationship (even after 50 years) wasn't all that good. Sounds to me like they were married but more for convenience after all the years they were together. Too much hassle at their age to start again. I'm not too sure about the shooting down of the drone and then Carol and Russell being shot down. Firearms in Australia are quite restricted for one thing, and for another, I would have thought the police would have found some evidence of spent cartridges, especially given they used dogs. However, saying that, it's not unusual for illegal cannabis growing activities in the bush, though I would be surprised if someone would have had an illegal crop so close to where people frequently camped. I wonder who bought the drone? Unfortunately, police information is at best, limited and sketchy (as always). I do believe personally though that there is something very amiss and that they didn't go "walkabout" and mysteriously disappear.
