Mike Pezzullo is worried about the apocalypse. In a speech at the Australian National University last night, the powerful Home Affairs boss outlined his vision of the various events which could end civilisation as we know it.

A year ago, few would have seen a global pandemic coming. Now Pezzullo warns we should start thinking about other security threats, like pandemics, which could come from nowhere and dramatically alter the course of modern life as we know it.

Sure there's climate change and extreme weather events but Pezzullo wants us to worry about other stuff straight out of the realm of science fiction: super-volcanic eruptions blocking out the sun; a powerful geomagnetic storm rendering all electronic technology obsolete; a crippling cyber-attack sending us spiralling offline; the threat (seriously) of terminator-like AI; an asteroid hitting Earth; a nuclear apocalypse.
