Dear fellow FT'ers!
Why not take advantage of the low value of Australian $$ against US$ and British pound amongst other currencies? Due to low Aussie wages prices for airfares are constantly very low even for locals. It is no problem to pick up a RTW Y-class fare for around US$1500. C-class won't cost more than US$3500. Please feel free to look for your best deal on the following sites:
