Complete bunkum.
Australia has refused to sign up with the 40 nations worldwide committed to phasing out coal. There is talk of the last coal fired power-station here closing down in 2038 but that is contingent on renewables taking up the full load, which is quite possible given our record levels of solar and wind power uptake, combined with proposed mega batteries and pumped hydro power schemes.
In the meantime, it is full steam ahead for coal. And good luck weaning the government off the royalties from mining coal and sending it to China, who are building new thermal powerstations like there is no tomorrow and encouraging developing nations worldwide to do the same by lending them the money and expertise to build them.
A quick search of Australian news sites, engineering sites, green sites, live steam and model steam sites and forums reveals not one word of a ban on coal fired locos or models there-of.
I cant access EIM until the digital copy arrives at our local library in the next week so remain mystified as to what they are talking about. There may be some grain of truth in it somewhere but I think they have their wires crossed as far as a general ban goes.
