Sounds plausible

I also assume, though, that part of the government's problem may be that there are absolutely no public servant heads prepared to advise them there is any plausible way to deny climate change is real and that Australia can go it alone in ignoring it.   Mind you, that has probably been the gist of the advice for years, but are they at the point of saying "Look, pretending to do something effective has become untenable"?
