I am 19 years old and I have a sister who is 17 years old, we are refugees who live in Finland and our mother live in Australia and she is Australian citizen.
We have been separated for 10 years and now we're planning to go to live in Australia with our mother because she is quite old now and she can't speak English. I'm totally perplexed and confused, I need advice because I don't know what kind of visa we need to apply? Because i'm adult and my sister is under-age. I was thinking if we go to Australia on a tourist visa can we apply for a permanent residence permit?
