Haha I know what you mean! It's gonna be hard enough living from a backpack, never mind looking like it!! I hadn't thought about it (think there's loads I should be thinking about eak) but if it's not too heavy it will probably be convenient. I went to Oz last year for a month and most of the hostels had laundry rooms but it might be easier for the odd thing to use your iron in your room?
I'm flying from Bham with Emirates. I'm the same as you work wise, work for the council here in legal services but want to try new things whilst in Oz! X
