My parents came to Australia from Holland when I was about 15 months old, and I'm still a permanent resident after all these years. I kept my Dutch nationality mainly because it allowed my kids to have dual nationality later on. It makes no difference to anything except that I can't join the police force, the armed services, parliament or vote in any State or Federal elections. (Luckily getting Morrison tossed out didn't depend on my vote). What I did find a bit ludicrous was that although I couldn't volunteer to join the army, I still had to register for the Vietnam call-up, which I did. My number didn't come up so I didn't go, but they got me a couple of years later when I went to Holland for a visit and promptly got called up for the Dutch army as part of NATO. Leaving Holland to go to England, the police picked me up as an IRA suspect and eighteen months later I got questioned by Special Branch for being a suspected people smuggler (after being traced by Interpol since I was driving a Dutch registered car). I'm probably lucky to be here at all!
