We are looking for a little help in Australia

Hello all good people,
We are loving couple with two little girls from Czech Republic and we have decide to move to Australia. We have a lot of trouble over here in Czech with politic situation and also people around here. We lived happily 10 years in USA and after coming back to Czech 5 years ago, we could not get going here:(  The only problem in USA was, we could not get to be legal over there.
If someone would be willing to help us, we would do anything to return it back:):)
