I'm trying to figure out best deal for an RTW in first class. Oneworld explorer is alright, there is also the world walkabout which at least in economy is pretty good deal.
I don't need many stops. I want to visit SE-Asia, Australia, New Zealand, Fiji at least, but LA or somewhere else in NA would be good as well. I can start from London and doesn't matter which way I go, east or west.

Any experiences of walkabout in business or first? Any ideas where to buy? Qantas web pages are useless and quote more than 11k GBP which cannot be right. Should be more like 5-6k GBP.
