Can anyone name this depressing movie? I want to buy it.

Here’s how it went: a man with a wife and five or six kids begins talking non-stop about how great Australia is. At some point they all move there and get settled. Then he leaves for the states saying he has work to do but he’ll be back soon. The family hates it there for quite awhile and they’re very upset their father/husband hasn’t returned. Then it dawns on them they need an income and it details their struggles to make ends meet in the outback since he is evidently never returning to them.
Anybody know the name of this movie?
