Now I think I understood....
The problem is that I am from Brazil. I want to move to Australia for good. But of course I would like to visit Brazil once every two years or so....
So I guess, in this situation, I would have to ask for a renovationyear, if I have to come to Brazil on holidays before completing 2 years in Australia. After completing 2 years, I can ask for a 5 year renovation....and after 4 years in Australia, I can ask for a citizenship. Correct?
