Not at all the same thing I'm afraid.
If a person in the US fails to repay a nonrecourse loan, the lender has no recourse against him except to foreclose of the assets used to secure the loan. End of story, he can continue getting on with his life.
If a person defaults on a loan in Australia the lender takes our securing asset, sells it and if he does not get enough money to cover the loan, the lender or his insurer will come after us.
The only time the lender will not be able to chase us up is when we declare bunkrupsy. And a lot of people can't do that.
Here is a good resource to build up your knowledge.
