Former WA premier Mark McGowan says Scott Morrison’s stubborn belief in a “one-size-fits-all” approach to managing COVID-19 was his biggest mistake when dealing with the States during the pandemic. Mr McGowan made the comment in the final episode of Nemesis, the three-part ABC series chronicling the nine years of Coalition rule that spanned the prime ministerships of Tony Abbott, Malcolm Turnbull and Scott Morrison. Among the episode’s highlights, Mr Morrison revealed how the process to convince the Nationals to support net-zero almost “destroyed” the Coalition. Former Treasurer Josh Frydenberg also confirmed that some colleagues including WA’s Ken Wyatt — approached him about replacing the increasingly unpopular Morrison ahead of the 2022 election. The episode charted the highs and lows of Mr Morrison’s tumultuous stint in power, from his “miracle” election win in 2019 to his infamous Hawaii holiday during Black Summer and his handling of the COVID-19 pandemic. Mr Morrison’s relationship with the powerful and high-profile premiers deteriorated as the pandemic wore on, as Canberra clashed with the States over lockdowns, financial support and vaccine supply. The Coalition’s ill-fated decision to initially support Clive Palmer’s challenge to WA’s hard border closure was considered a major factor in its wipeout in the State at the 2022 election. Mr McGowan — who had a good personal relationship with Mr Morrison said he and his fellow premiers were never trying to “play” the prime minister. “We’re all just trying to get the best outcome for our States … we’re all just trying to protect our people as best we could,” he said. “He (Morrison) was just too centralist. He just always had the view that it had to be one size fits all.” The Coalition’s standing with female voters plummeted during 2021 as Mr Morrison struggled to grasp the uproar that followed Brittany Higgins’ rape allegations. In one withering assessment, former senior public servant Martin Parkinson told the program: “I don’t think he ever really valued womens’ perspectives”. Coalition women interviewed for the program disagreed Mr Morrison had a problem with women but said he could be “clumsy” with his language. Mr Morrison agreed with that assessment, joking that “suburban Dads can be a bit clumsy with their language”. The program offered a fresh insight into just how concerned Mr Morrison was that the Nationals might refuse to sign Australia up to net zero by 2050 ahead of the UN climate summit in Glasgow in 2021. Nationals frontbencher Bridget McKenzie recalled a “heated exchange” with Mr Morrison about his “assumption” the junior Coalition partner would blindly support the Liberals’ position. “It was the height of disrespect for the Prime Minister to think he could pack a kilt to Glasgow and not even consult on the second part of Government’s view on net zero by 2050,” she said. Asked if it was difficult to secure the Nationals’ support, Mr Morrison said: “It was probably the hardest thing within the Government that I had to achieve”. “It almost … destroyed the Government”.
