I believe the World Journey fare would cover Sydney. This includes CO, NW,KLM, EK,AS,Copa, South Africa, Kenya, Air Europa, Malev, MH, Air Caledonia and a few other pacific carriers. To get to Sydney you could use Malaysia, Emirates or Air Caledonia via Tokyo to Noumea to Sydney. As others in other forums have mentioned , this combo may disappear as NW,CO,etc participate in the Skyteam RTW. I enquired through NW about this fare 3 weeks ago as I will probably be using this in July and August and the agent mentioned that it was still available for now. She could not tell me if this fare would disappear anytime this year.
