In the 1990s, seeing a ‘hot-red weapon’ of a motorbike being ridden into the News Corp car park in Sydney, journalist Paddy Manning could not help but ask, ‘What’s that?’ Still wearing his helmet, the rider answered that the bike was an MV Agusta – at which point Manning realised he had yelled at Lachlan Murdoch.

Last spring, as the harbingers of a dangerous season converged into a chorus of forewarning, I decided it might be a good idea to keep a diary of the period now known as ‘Black Summer’. The diary starts in September with landscapes burning in southern Queensland and Brazil. Three hundred thousand people rally across Australia, calling for action on climate change. I attend a forum of emergency managers where, during a discussion about warning systems, a senior fire manager declares: ‘We need to tell the public we cannot help them in the ways they expect, but we’re never going to tell them.’ Next week, Greg Mullins, the former NSW fire and rescue commissioner, comments on ABC radio, ‘We’re going to have fires that I can’t comprehend.’ Federal politicians assure the nation that we are resilient.

In 2016 John Kaye was dying. Once leader of the Greens in New South Wales, he had a final message for his party. ‘This isn’t and never has been about changing government … This is about changing what people expect from government.’ In our era, dogged by chronic distrust of parties and government, it might have served as a rallying cry for people to transform politics by demanding more of their representatives. But Kaye was a man of the left, and in the context of an impending election, as the Greens descended into vicious factional brawls over preselection for his seat, his words unleashed a storm of controversy over the direction of the party.

This is just one among many eruptions of internecine warfare over the purpose of the Greens chronicled in Paddy Manning’s comprehensive history. The survival of the party since 1992, despite the elaboration of a program, and despite its professed commitment to consensual democratic processes, has depended on its leaders: the iconic Bob Brown, then Christine Milne, and lately Richard Di Natale.

Future generations of readers will invariably look back in awe at the second decade of twenty-first-century Australian politics for its ridiculous revolving door of prime ministers. Personal and journalistic accounts of this rare instability – Australia had six prime ministers between 2010 and 2018 – have certainly proved a publishing bonanza ...
