They consistently rank as one of the best banks in Australia on every comparison.
Hardly anyone knows what a Credit Union is - that's why they removed it from the name (it is still a credit union. And a credit union is a type of bank).
I have no experience with any of the other banks that score as well as Great Southern, they're probably good too but I'm so happy I don't want to switch. I went through close do a dozen banks before finding this one.
