Well I've lived here for over 6 years and disagree with pretty much all your points WalkofShame, and that's why anecdata is pretty useless. But I'm going to respond anyway. Having lived in three countries for extended periods and used the healthcare in all three, it is so much better here! I can get free same day doctor's appointments, and when my son had a burst appendix the care he received was superlative, as was the hospital he was in which had an entire top floor filled with a free gaming arcade, basketball court, teenagers hangout and DJ booth, all for patients use. I also supported an old friend through his last stages of cancer, and the support and palliative care he received in the last year of his life was superlative (and free). He was supported to die at home, and the short stints of respite hospice care he received were fantastic, certainly nothing like Chernobyl
And as for racism. Its everywhere. There is just as much racism in the UK and Ireland.
As for houses being 'self-contained' and there being no sense of community, well yes most houses are detached as there is more space here in the UK, and there is plenty of community where I live!For example every year we have Neighbours Day every year, where the local government actually gives you money to host a gathering with your neighbours! Last year we had a bbq on the foreshore, it was great fun!
Yes it is expensive here, particularly if you are on holiday, and the exchange rate is poor. But wages here are so much higher, so once you are on Aussie wages, a lot of things are cheaper. We certainly have much more disposable income and a better quality of life here because of that.
Anyway, I realise you said other areas may vary, I just wanted to point out that this is very much the case! There are shitty bits of Oz (I enjoy visiting Sydney and Melbourne, but wouldn't want to love there!), just as there are shitty bits of the UK. But don't write off an entire continent because of them!
