Long, long ago I opened a bank account with a building society. Time passed and the building society combined with another building society, and then was bought by Advance Bank. In something resembling a biblical chain of banks begetting banks, Advance Bank became part of St George Bank and lo, it was good. Or as good as any bank ever seems to be when you’re on the customer end. Then the earth shook and the shares crumbled and so it passed that Westpac bought St George Bank, decreeing unto the customers who probably detested “the big four Australia banks1” that St George would continue as a separate entity.
