Sorry, but simply untrue. There are great number of opinions either way but the majority seem to favour lowering pressure. My experience has also been that lower pressures are better, though I don't go as low as some suggest. For my Landcruiser Troopcarrier running BFG A/T on 8" rims I have found about 5-7psi below highway pressure is good (so ca. 32 front and 37 rear). Much reduced shake, better traction and no tyre damage (and I've driven all the roads Mike is considering traveling on). People here take work vehicles out to central Aust and generally don't lower pressures. They haven't had too many punctures but they do chew out the tread in no time flat. [ Of course one bozo let the tyres right down to get through sand and then drove back to Wollongong at that pressure. He delaminated the tread from the case.]
The other thing the experts say is that every vehicle/tyre/load combination is different. So it could well be that for Mike keeping to highway pressures is the best. One thing is certain, the faster you travel the greater the strain on the tyre. Certainly check the spare before you leave and make sure you have all the gear to change a wheel - just last holiday I loaned a wheel-brace to someone who found he had the wrong sized socket. (While I'm at it: carry spare water and maybe also some food. Those roads aren't truly remote but it will still be hours between vehicles. If you get stuck you could be there overnight. I also carry a reasonable first aid kit.)
