Welcome to FT!

FT is mostly American, but nowhere close to 100 percent. There's an active Oceania forum here. It tends to be mostly about Australia, with the rest split between NZ and everywhere else in the area. Lots of Aussies there. There's also a regular FlyerTalker gathering in Australia* in late May, going into its 12th year soon, with a full weekend of festivities and attendance that is typically in the 30-50 range. It will be on the Gold Coast this year. More information in this thread in the CommunityBuzz section of FT.

A couple of years back I had a delightful dinner with some Australian Frequent Flyer (www.austrialianfrequentflyer.com.au) folks in Melbourne. They seem to be a friendly bunch - even by Australian standards, which are friendlier than most other places would be. I'd try that, too.
