Five Months Around The World

Hey there, my proposed route thus far is Rio - Santiago - Fiji - Auckland - Australia (3 months) - Singapore overland via Kuala Lumpur, Butterworth & Penang to Bangkok - Dubai and back to the UK Anyone with suggestions for places to see/things to do along with way will be greatly appreciated - i've got lists for each place already but i'm open to ideas! We'll be spending a month getting to Australia, three months there and about three weeks getting back to the UK, spending 5 nights in each of the destinations listed along the way :)
