Yes, one of my relatives was a criminal and sent out. Criminals always return to the scene of the crime, so here I am.
Any way, I have a UK passport because my father was born in Scotland. My husband's grandparents were born in Scotland so he has a visa.
If your parents/grandparents were born in Australia you'd have the same access.
If you want to complain about "fair", then why don't you compare both countries immigration policies. You'll find it a heck of a lot easier to get into Australia than vice versa if you have no ancestral rights.
Protectionalism? Don't make me laugh. Go and compare converting a JAA licence to an Australian one and vice versa. JAA land are past masters at protectionalism!
When I worked in Australia, a great deal many of pilots had "foreign" accents. Whether it be American, Canadian, French, British etc. They all had one thing. The right to live and work in Australia.
