My dad seemsd to think we can move to Australia (he already lives there) for 2 years, get our passports then just come and go as we please. My friend lives in America and has US and UK passports.
So can you really just come and go as you please? Or do you have to notify that you are leaving the country/come back to the country?
eg... If my friend came to live with us for 6 months does she have to notify anyone that she is back here or can she just come back and start working as if she never left?
