Since Australia hasn't set any legal targets for EVs, companies like Volkswagen have no incentive to sell their limited production of EVs in Australia.
Considering the solar and mineral resources they have, this is a tragic waste. Presumably they'll catch up soon though as it becomes unavoidably obvious how dumb they are being.
edit: only thing I missed was discussion about getting cheap electricity prices by acting as demand response and/or virtual power plants, possibly with colocated storage. I'm assuming that's part of the big players business plans but it doesn't get talked about a lot in public. Just hints from Tesla.
