Australia New Colors

My wife noticed that the Australian atheletes in the Olympics are all wearing yellow-and-green themed uniforms. Why is this? Their flag is mostly blue with white stars and red in the “Union Jack” area. Did they pick the Olympic rings’ colors minus their flag’s colors?

Australian athletes have been wearing yellow for quite a while.

Sometimes the colors on the flag don’t have much to do with the athlete’s colors. The Italian soccer team wears blue and the Germans sometimes wear green. You won’t find those colors on those countries’ flags either.

Green and gold are Australia’s national colors. From this site:

I wondered the same thing during the opening ceremony. Now if someone knows why people were wearing what looked like green and gold socks on their hands at said ceremony, I’d love to know.
