Australia sounds awesome to me because of the heat and beaches and everyone has a high income over there.
UK is ok where I'm from, like gun laws, free healthcare and LGBT rights are on point but it's boring for me
US would be amazing in somewhere like Cali or NYC but I don't wanna get shot going to the movies and overly obese people annoy me and I don't want my health to be reliant on my income
Canada.. nah, too cold, too boring
Australia wins for me
If you think The UK is boring, there's no way Australia is right for you.
I can't imagine not living on Australian beaches and 43*C (110*F) summer days. I want to live in America and the UK though. Except minimum wage for a dead-end job in Australia is like $34,000 per year. So if/when I do move overseas, I want to save up a LOT and develop a strong career before I have to go on a US salary.
