Think twice before you book with them. I travel a lot around the World and I've never experience such a strict baggage policy! If you think you can go away with online check in and continue with your bags 'you are wrong' ! You can have two carry on bags but total weight (of both of them !) must be 7 kg max ! They weight your bags next to your boarding gates and give you orange stickers to confirm you've been checked so it is impossible to avoid it. If you exceed 7kg, $75 will be charged so if you think you will save by booking with them, compare the prices and book with maybe a bit more expensive Virgin Australia (which I can recommend) but at least you will not be surprised with additional costs. Also on board staff wasn't pleasant prompting to put my crossbag (which I wore) or my jacket which was on a hanger to put on under the seat in front of you which doesn't make sense.
