I'm sure Qantas in Geneva would be happy to oblige (022 567 5161 or 022 906 1212).
Alternatively, I just called the AA RTW desk for free via Skype, on +1 800 247 3247. I'm sure they could set it all up for you & then you get AA Switzerland to do the tickets.
The link to the
OneWorld route map helpfully posted by
DownUnderFlyer earlier today readily shows the routes and times from HNL to Oz.
