C-17 of the RAAF in a special 100 years livery to commemorate 100 years of the RAAF in 2021.
There was also a 100 years livery for an A332 MRTT. This aircraft didn’t have a suggestion, nor was it in game, so I omitted it from the original post, but during writing of this one I noticed that and so wrote the MRTT post as well.
