Australia will 100% not be swapping. There is zero debate about this, there is zero will and there are far more pressing issues to deal with than adding this significant cultural change.

And I have no idea why Japan changing would be the catalyst.

Without Japan the market for those cars might no longer be tenable. Australia and New Zealand buy a lot of Japanese cars.

I don't think Japan will change drive lane in the future, but possibly used car export could be decrease for BEVs. Japan adopts CHAdeMO for fast charging but other countries don't, so it will become harder to export. Also China is becoming very strong BEV manufacturing country. For new cars, after EV transition and steer by wire system become popular, LHD/RHD will become minor difference for car designing.

6 of the 10 top manufacturers of cars in Australia are from Japan. That said I can't imagine Japan doing that, and to be honest it's not uncommon to see LHD cars on Japanese roads (American cars).

Australia doing that would weird, as I think it'd an eight jurisdictions to sign up to it. That said, I can see WA doing it absolutely.
