The flying kangaroo has morphed into an increasingly stylised version of its' former self. Qantas has been pretty clever not to overly mess with the brand, red with a flash of gold, flying rat and the font staying fairly similar over the years. I like the 1984 - 2007 livery, at least the 'roo had paws!
