I have recently found the following site;
Aussie Airline Uniforms and Collectibles.
As the title says, it's about Aussie Airlines uniforms but also contains much more information. If you're on this forum you'll probably find something of interest on the site and may even be able to help with questions re uniforms, badges etc. Darren who runs the site, is very approachable and easy to get on with and he's constantly updating the site as new info comes in.
