Crookneez:
I tried to answer you with a private message, but apparently I haven't posted enough messages yet so I haven't earned the right to send private messages. I therefore hope the rest of the group will have a little patience. Sorry, everybody!
I was born and raised in the UK, but have spent most of my adult life in the USA. My middle brother was a "ten-pound pom"(1960), then my parents emigrated to Oz (1971) and finally my youngest bro (1973). I have visited Oz about 20 times, and worked there as a consultant for 3 months on 3 separate occasions. I was widowed in 1985 and beginning to apply to emigrate to Oz in 1986 when I met my present wife.
So I suppose I'd consider myself a "Halfstralian" (but that doesn't buy me anything with Oz Immigration and Customs!)
