I haven’t had any with Bank Australia, so I’ve either just never got close to overdrafting, or they have a way to turn off overdrafts.
Edit: looks like they definitely have an overdraft fee, and I don’t see an obvious way to manage it. Pretty sure you can ask any bank to turn it off though.
There’s banks without overdraft fees in Australia?
