For me personally I never support Australia (Socceroos). Maybe the only exception is against FYROM but I recall when Turkey came here to play a series a decade or so ago I was so indifferent I didn't care who won.
Even as a little kid watching Katholos, Raskopoulos, Kalantzis I just never felt the pull of supporting Australia. From a really early age (like 4 years old) I was just very aware of my Hellenic identity as opposed to my brother who does support Australia (except against Greece) and takes it personally when they lose etc.
I don't even care about being called a traitor or disloyal to Australia as I'm intelligent enough to know that if I really do live in a free state then I can follow any football nation I like. It's not like I'm selling state secrets to Kim Jong Il or to the Ayatollah's of Iran. If anyone has a problem with my position then it's their issue and not mine so just deal with it.
Amen and Forza Hellas!!!
