RE: Australian Air Passes. They are wonderful, but push your agent or the Qantas or Air New Zealand agent to see if there are cheaper options re: zones. In some instances, they can come up with cheaper fares that require date and time, but which can be changed without a penalty. Have them look at the MINTL fares. I know it's lowered the cost of my ticket several times, and I always start with the Air Passes in terms of ticketing after the LAX-SYD leg,and then go on to a quote on MINTL, etc.
