A couple of years ago on a trip from Port Stephens across to Port Augusta, then up through the centre to Alice, across the West MacDonnell Ranges, Kings Canyon, Uluru, then back home, we encountered the big mouse plague. We had a soft floor camper, and found the only place the buggers could get in was through the holes where the tent dropped down beside the trailer, at the frame hinges. The best thing we found to stop the buggers getting in was to stuff staino pot scrubbers in the holes. This plague was almost all the way on that trip from across Western NSW, VIC/SA corner and through all the way out west. They were crawling over and under the tent from as soon as the sun started to go down till it came up the next morning. Saw a couple of people that had wiring chewed up under the bonnet, so we left our bonnet up over night and luckily had no problems.
