You would be correct if Codie lived in the United States but she doesn't. She lives in Australia and in Australia there is no such thing as a credit rating. There is a credit history but credit histories in Australia only report when you have failed to make payments. There is no difference between somebody that has never borrowed money and somebody that has borrowed (or does borrow) extensively but always pays as agreed. Therefore, the bank manager is perfectly correct in saying that there is no such thing as a good credit rating.
