I understand all you have said about Oz, its not for everyone.
Personally Im not arsed about old buildings, what floats my boat is colours, sounds daft but turquoise ocean, white sand and tropical flora suck me in every time, I hate being cold.
Oz is a young vibrant country of which most of its citizens are proud, I dont mind my kids having an Aussie accent as I know they live in a safe, beautiful country with friendly people who dont take life so seriously.
You can live in nearly every climate in Oz as its so vast, if you want a cool place that looks like Yorkshire theres Tasmania, or you can have a Spanish hot temperate or Tropical in places like Cairns, Townsville & Darwin, we have ski resorts on the Southern Alps in Victoria and tons of tropical islands to visit (or live) off the Queensland coast.
Medical is free as in UK.
Also nearby is New Zealand, I go there often to see friends, if you've seen Lord Of The Rings you'll know the scenery is awesome.
Australia has loads of free public toilets and showers which Europe doesnt seem to believe in anymore lol.
Its all down to the individual and thank God we have choice. If you like old cities like York and Chester dont migrate to Oz, but if you like clean & modern then it might be for you.
