Going to western Australia (renting a house near Margaret River) in February. The cool part is we'll be going through Abu Dhabi and we're spending a few days there on the way back. Will get to drive the Yas Circuit, see Ferrariworld, the Louvre, Grand Mosque etc.
We've been all over eastern and southern Australia and NZ but never out west. Really looking forward to it.
BTW if you're going to dive the Great Barrier Reef rent a house up there. We've rented from these folks a number of times- luxury properties cheaper than most hotels.
