As stated on previous posts, Aussie Decals and Red Roo Models are the go. As far as I know, Aussie Decals don't have their own website or store but their products can be purchased through many outlets (Sandle Hobbies, Dave's Hobby Centre & Snowy Mountains Models spring to mind - all in Australia).
Until very recently there was also a very good range of RAAF, RAN and Aussie Army decals by Hawkeye Models (part of the Model Alliance group) but production has unfortunately been terminated. I've heard from one of his suppliers that the decal manufacturer became so pissed off with "rivet counters" arguing about minute details on his decal range that he gave it up in frustration. An excellent range of decals is now gone
- thanks, d*****ad rivet counters! You may be able to find the odd sheet of these still in some stores, however.
