Banking institutions make virtually all of their money from loans. I'll tell you one thing, if I owned any stock in Bank Australia, I would sell it all right now. IMO they are headed for disaster.
Australia will never go to BEVs like the US eventually will. Anyone who has been there will tell you that outside of the big cities in the east, there is a whole lot of nothing in Australia. It would take several weeks to drive across the country in a BEV (if they had enough charging stations).
