True Blue

In Aussie slang to call someone "Blue" or "Bluey" means they've got red hair.

In the early European migration days (convict days) a lot of those people

were of Celtic origin with a significant proportiion of redheads.

So to call someone "True Blue" means that they could trace their origins

back to a convict arrival. It's close to the best compliment that you

can give to an Aussie.

Thanks mate, I really appreciate your help. You're true blue.
