Expo!
Sounds like a great start to a RTW adventure, We will miss you by 12 months as we should be there in 2016 - Europe and Morocco this year for us!
Thought I'd post anyway as we might see you somewhere else on the road as it sounds like you will be travelling for a long time and it's always nice to meet fellow Aussies! Interested to hear what you think of the Expo, build up our expectations!
Travel safe - cheers Justin
