Best of luck on your remaining weight loss journey Camplestar and have a great time in Australia..
I am also hoping to lose a large amount (7 stone 8lbs but have already lost 2 stone 9lbs) by christmas as I am going to Sweden
You will have a fab time in Australia by yourself. I spent a year out there and travelled by myself. You meet so many people in hostels I'm extremely jealous! And you'll look fab on bondi beach when your at you target
