my opinion is...
i think everybody has the right to be proud of their background, and they should be respected for it... however you should feel very obliged to respect your home country (australia), if you live here your using the land and its resources, and you should appreciate that...
you dont need to call yourself fully australian, but you shouldnt completely disregard the nationality... why do you think the cronulla riots started lol
i know it would be difficult, if i were to move to another country (to live there for life) adopting their name would be tough, but i would do it
along with calling myself australian...
may i ask, do you have something against being considered an australian? if so, what?
