Most of WA is at least as hot as Darwin (just not humid) and the dealer here uses 5W30. With synthetic oils they don't lose their viscosity when warm (like old mineral oils did) and I can't imagine that anything other than specification oil should be used for the engine.
You might also think of changing the transfer case oil while doing the transmission. At 60k, mine smelled of dead fish when I had it changed. This oil is at least as expensive as the transmission fluid, but at least it didn't need a double-flush. May also want to make sure front and rear diff oils are good.
