The question is too vague and it needs additional factors: what do you define by the word success? Are you talking about getting residence permit or integration in the local society? Or perhaps you mean getting a job?I have often considered Australia as a destination for my second period of life.
How hard is it to relocate there if you live in an EU country for instant Scandinavian country?
What would be minimum requirements to succeed?
I have a South African friend (an accountant) who moved to Australia (no money, employee) and he always says that with money (not being a potential liability for the government) it's way easier and faster - ask an Aussie immigration lawyer and you'll know...I have a job, no need for that. Own several companies worldwide. Doing 1 million USD a year in profits after tax is paid.
So my question is, can I just take a flight there, stay for 3 months and in this 3 months apply for permission to stay there for another 5 years or so? What shall I do to get started if I don't want to leave the country after 3 months and live as a tourist?
