I'm not sure if this is the case in Australia, but I always ask if I can get an upgrade when I call them and, if there is any available, I usually get one at no additional cost. It never hurts to ask!! We have two separate accounts (me and husband) and I give them both numbers and we are offered mostly balcony cabins. The last cruise I booked, we got an upgrade from a balcony to a Junior Suite. If you go to ClubRoyale.com and put in your account number, you can see what cruises are available to you. Good luck!!!!
