Hi Rosequartz
Yes, Australia is a melting pot - I love that aspect of the country. We came here in 1979 because Thatcher got elected and we knew she would do terrible things. We had a new baby and had his future to think about. It worked out great for him and his brother, born here three years later. They are both university-educated, happy, in stable relationships and with good career paths so I guess we got what we wanted.
Trouble is, we do get homesick, and I read the UK news every day. But we have some very good friends, and have a secure life in retirement, on the Australian government pension. The Queensland climate is a plus, too.
I do worry about problems with Islamists in the UK (as opposed to every day Muslims), and those nasty stories about schools getting infiltrated by these horrible fundamentalist islamists. How much is true, and how much is hype I don't know, but such tales are pure gold to far right wing parties.
My own solution to politics is to stay with mainstream parties, in my case, the Labour party. They will usually have moderate policies, and kick out MPs or candidates who cross the line in any way. Mind you, our current Tory party is getting a bit extreme...time will tell how bad it all gets. There's always the next election. And here, we all have to turn up at a polling station, or do a postal vote, or cop a fine.
