we do often bear our flag: wave it or paint it on our face, but to wear the colours is a bit of a no,no.
Green and Gold are the colors of the Wattle tree, a truly symbolic Aussie native plant, so these are the colors we proudly display.
there has been so much controversy over our flag its just easier i think to opt for the green and gold. Imagine if we were at the rugby wearing recreations in our garments of the flag - wouldn't we then practically just be supporting England anyay?
