Thanks guys.

It actually got a bit hairy on Saturday night. I used the parker lights on the ute to light up the foreground and would set my alarm to wake up every hour or so to run the car and keep the battery charged. However, I slept through my alarm for about 4 hrs and woke up to a dead battery. I was perched on the side of a hill with about 5m behind me and had to do a reverse roll start downhill, luckily it worked first time because I wouldn't have had another chance and it was a good 10km walk back to the highway. So, I will be buying an LED flood light in future that can run off a separate battery to prevent being stranded.

Also found a snake under the tripod at one point when I checked up on the camera, luckily it was only an olive python so I picked him up and moved it out of the way, if it were an eastern brown snake (which are pretty common), I'd more than likely have driven back into town to get the rifle before moving him off. I'm not big on killing snakes for the hell of it, but if it came down to either him or me taking posession of that camera then he'd have to lose that custody battle.
