When our armed services reflects a more diverse, multicultural nation prepared to defend it's nation irrespective of where they or their parents originated from, then and only then will I agree that those who have immigrated here, and or their offspring truly value us as a race unto itself, a nation worthy of their undivided loyalty, respect and admiration.
Have you been out to the the barracks lately, tell me, why is it that a majority of those who serve in our nations armed services, don't reflect a more "multicultural" Australia?
A majority of those willing to serve their nation are caucasian, despite our obvious multicultural shift.
I think it's this brand of patriotism which speaks for itself, don't you?
Good enough to immigrate here, but not good enough to defend?

...Some immigrants appear to be more willing to Australianise than others, you need to drive out to the suburbs more, might I suggest a stroll through Canley vale, Cabramatta, Chester Hill, Bass Hill, Lakemba, Guildford, Villawood, Grandville, Yennora, Merrylands, Auburn, Lidcome, Fairfield, .... we have a 2nd and 3rd generational Lebanese/Asian youth culture, complete with their own accent and street culture/dress code, as though they walked off the boat yesterday...and nothings been done about integrating these people into Australian society responsibly, never has it been our governments priority.
I think you need to go for a drive out into the suburbs a little more often, to the places I listed, because you don't have to be a social anthropologist to realise how many of these once thriving middle-class and safe neighbourhoods have become impoverished ethnic slums that noone with any self respect wants to buy in, due to having been both socio-economically and racially-demographically stigmatised.
Are regarded ethnic sprawls!
Not all of us walk around with our eyes closed, this and do take a drive through these revolting suburbs from time to time just to compare them to how they used to be.
We can irresponsibly immigrate true, but we cant hide our growing slums of social depravity and cultural disadvantage in OZ forever.

...A word of advise, don't get out of your car.
And make sure you have glass insurance, if you do.
So, why are a majority of those willing to defend their nation Anglo-Saxon?
Where is this multicultural and "Australianised" nation of 2nd and 3rd generational folk you speak of?
