Of course we should promote coal, why wouldn't we. We are the biggest exporter, it would be hypocritical for us not to use it.
Global warming is crap, dont throw away Australia's main advantage in the world, until you can offer a credible alternative.
Coal exports pay for our hospitals and schools. Adani mine royalties will be 3 billion a year alone, and we are broke due to labor spending.
Now you propose to be rid of coal, for no valid reason. Get some sense.
