Like public health officers around the world he has been at the centre of political dispute,and has entered the public psyche as a hero and,to some,a villain. You can buy Brett Sutton mugs and doona covers. He has several passionate fan clubs on Facebook. You can also find memes of him with devils’ horns.

Meanwhile,the government and the citizenry,by heeding his advice,on Friday saw Victoria notch up 28 days with no new cases,technically eliminating the virus from the state.

Public health is inevitably political. It is about systems – such as clean water and air,toilets that flush and vaccination. It implies government action – building infrastructure,encouraging and even controlling individual behaviour. When public health works,nothing happens – meaning governments around the Western world have tended to undervalue it and underinvest. Victoria is no exception.

Sutton has done his work within the mega Department of Health and Human Services – created by amalgamations in the early days of the Andrews government. It has been variously described as defensive and dysfunctional.

His position is unusually junior,given that he wields exceptional powers under public health legislation. In other states,he would be near the top of the departmental tree. Here,he is in middle management.

Sutton’s predecessors as chief health officer lost their positions to the politics.Rosemary Lester retired after being vilified for her response to the 2014 Hazelwood mine fire. Her predecessor, Dr Robert Hall,was sacked in 2007 by Labor minister Bronwyn Pike,taking the blame for allegedly poor handling of a gastroenteritis outbreak in aged care.

Professor Jodie McVernon,director of epidemiology at the Doherty Institute,says this history has affected public health in Victoria and created “a risk averse culture … people hold tight to their section and their accountabilities". Perhaps that risk aversion was the reason the department refused Sutton permission to be interviewed for this article.

When the pandemic began,Sutton asked to be given the position of state controller for health,leading the response. Pandemic plans assumed this role would be filled by the CHO,but he was sidelined in favour of a senior department official. The department continues to argue that,given the CHO's many responsibilities,it would have been impossible for him to fill this role as well.

But others with knowledge of the department see this as part of a pattern in which the career bureaucrats who run DHHS are in conflict with the medical practitioners and lack an understanding of the operational side of public health work.

In September,at the height of the second wave,Sutton told a webinar of University of Melbourne medical students that he understood the passion – both the fandom and the hatred – surrounding his work. “You are reaching into the most intimate aspects of people’s lives,their sovereignty … and constraining them in ways that are unprecedented.”

He said he tried to separate himself from both the adulation and the hatred. “There will be mistakes made ... All you can do is be purely motivated to protect life and limb.”

Since January he had been working 15-hour days,six days a week,starting at 7am with meetings of the emergency response team,then meetings of the Australian Health and Protection Principal Committee – the key body comprising state and federal CHOs that advises the federal government. Then there was the daily media conference and meetings to gather the latest data from his team. He ended after 9pm with briefing the Premier or his chief of staff.

The students asked him how he coped. He talked about the three pillars of good health – exercise,sleep and good food,though admitted all three had been in short supply at times. He talked about his wife,Kate,and their three children,aged between 5 and 10,and the “oxytocin effect” of cuddling them.

And he talked about meditation. Sutton describes himself as a “bad Buddhist”. He has written,in the past,about how Buddhism is relevant to medicine. It teaches a deep understanding of the suffering in the world,and also the ability to transcend it.

Under the business shirt Sutton wears to press briefings,he sports a number of tattoos – one sign,he has commented,that he is an outsider in the bureaucratic culture. People find him personable but sometimes a little alarming. He can give a devastating stare when he is unimpressed – though he never gets heated or raises his voice,colleagues say.

He entered the public service late in his career,and at the onset of the pandemic had been CHO for just one year.

In an article published last March in public health news serviceCroakey,Sutton emphasised the importance of communication in public health.

It had taken him a year to get permission from DHHS to establish a CHO Twitter account,he said,and another month to be allowed to use his own photo.

Since then,the account has to some extent liberated him from the slow and cautious approval processes of departmental communications.

On February 23,he tweeted that a pandemic was “very likely,if not inevitable”. That made him one of the first government officials in the world,and certainly the first in Australia,to say this. He toldCroakey:“it caused some ructions and I copped some criticism for it”.

In late March,the federal government’s deputy chief medical officer (now acting chief),Paul Kelly,described Sutton as a “dissenting view” on the Australian Health and Protection Principal Committee.

Most CHOs were in favour of the federal government’s “proportional,scalable and sustainable approach”,said Kelly,but Sutton was tweeting #gohard #gofast,pushing Victoria into more urgent restrictions on public gatherings and more stringent lockdowns. “I’m being blunt again to save lives,” he tweeted.

In late June,he sent the Premier the genomic testing report that established Victoria’s second wave had been seeded in hotel quarantine.

Within hours,Andrews responded by announcing the hotel quarantine inquiry,and began to shift responsibility for the program from DHHS to the Department of Justice. According to a departmental source,speaking anonymously because they were not authorised to speak to the media,Sutton’s colleagues felt he had blindsided them.

Documents before the hotel quarantine inquiry show that at this point that Jason Helps,one of the people who had got the State Controller job after it was denied to Sutton,forwarded himself an old email trail that could be read as suggesting Sutton was more central to decision-making over the quarantine system than he had claimed. These emails later leaked to the media,and as a result were given to the inquiry. The Department has claimed it was still “actively considering” whether they needed to be revealed at the time of the leak.

Sutton’s blunt speaking continued. When thenhealth minister Jenny Mikakos claimed in August that most COVID-positive healthcare workers had acquired their infections outside work,Sutton did not back her up when asked a direct question about it by the ABC’s Raf Epstein. The minister was working off old information from the first wave. Sutton believed most infections were work-related – which later proved correct. A departmental source,speaking on condition of anonymity,said Mikakos was angry.

Then,in early Septemberin a conference call to Royal Melbourne Hospital doctors,Sutton was frank in acknowledging the shortcomings of the state’s contact tracing,at a time when Andrews was still minimising this. A recording of the call was leaked to the media.

More recently,this weekhe appeared before a state parliamentary inquiry into contact tracing and reiterated these concerns,as well as saying that once cases topped 200 in late May – after a rapid surge following a super spreader event – even the best contact tracing system would have been challenged.

On these accounts,both the history of underinvestment in public health,mismanagement of aspects of hotel quarantine and a fair dose of bad luck were the story behind Victoria’s second wave. The state awaits the findings of the hotel quarantine inquiry,due on December 21.

If,like his predecessors in the CHO position,Sutton falls victim to politics and blame games,it seems likely to spark a revolt in the medical community. There,it is hard to find anyone who has a bad word to say,and none of the many people contacted for this article doubted his integrity.

Brendan Crabb,director of the Burnet Institute,thinks few people understand the immensity of what Sutton has been through – a relatively new CHO in a relatively junior position “hit by the train” of the pandemic.

With Victoria so far the only state to suffer a second wave,he has been relatively isolated and under party-political attack from the state opposition and the federal government. “To be able to say after all that he's consistent and calm and trusted and modest and respectful and clear is incredible ... I know I couldn't be that person.” Crabb’s comments are typical of what other members of the medical community say about Sutton.

But the politics inside the DHHS is clearly much less friendly. Evidence before the Hotel Quarantine Inquiry shows that Jason Helps felt Sutton had “distanced himself” from the hotel quarantine operation when the blame game began. Helps “had concerns” about Sutton’s claims not to have known about the use of private security companies. Sutton has stuck to his assertion that he was sidelined. This is supported by an email he wrote in mid April protesting that the scheme had been set up without his approval or input,thatthe exclusion of the public health team was “astounding” and that it was being run as a logistic exercise rather than a health program. “This is a source of unease – moral and legal,” he wrote. But even if Sutton had known about the use of private security,it probably wouldn’t have changed things. The problems with that workforce were not on anyone’s radar at the time.

Behind the scenes,Andrews has been heard expressing frustration with Sutton,and news of this has leaked.

But a source with direct knowledge of the situation says the tensions have not been over fundamental matters,but rather,in the daily stress,the Premier’s perception that Sutton has not always helped with consistency in messaging on coronavirus restrictions,and has sometimes been underprepared on the detail.

There was also the time Sutton offered to speak personally to the Afghan community in the south-eastern suburbs after a COVID-19 outbreak,saying he had “been to Afghanistan a couple of times”. Andrews was unimpressed. He had been at pains not to single out ethnic groups,and the Afghan community felt targeted. Sutton later apologised.

But none of those involved knew Sutton well enough to understand what lay behind his lightly mentioned “couple of visits” – or how central they were to his identity and sense of mission. On graduation,Sutton spent 10 years working in emergency medicine in various hospitals,with a long stint in north-western Tasmania. This was interspersed with travel,and work for Medecins Sans Frontieres,starting in Afghanistan. Sutton met his wife,Kate Sutton,in Afghanistan. She was also a humanitarian worker and today is the founding co-director of the all-female NGO the Humanitarian Advisory Group.

His mother,Ann Sutton,was terrified when Sutton went to Afghanistan. On his first visit,the Taliban were still in power. On his second,they had just been overthrown by the US. There were landmines and accounts of awful injuries.

“He would say to me,‘there’s nothing I can do’,” she recalls. Holdaway says Sutton told him how his team would arrive in a village and gather everyone together,then sort them into groups by calling out symptoms – those with diarrhoea in one corner,with coughs in another,detecting who had dysentery and tuberculosis. In the advanced TB cases,Sutton would have to take the patients into a corner and give them the hard message. “You are going to die and there is nothing we can do.”

“It was gut-wrenchingly honest,” says Holdaway. Sutton acquired “the kind of perspective that never leaves you. He doesn’t get caught up in First World problems”. Work followed in the refugee camps in Africa,and in East Timor. It was this work that turned him from emergency medicine to public health.

Sutton,says Ann,was a quiet and thoughtful child with a quick wit. Two events formed him. The first was the sudden death of his father,Terry,from a stroke when Brett was nine years old. For 18 months he refused to speak about his dad. “It was as though he hadn’t had a father,” she recalls. She consulted the family GP,who said her son was displaying the signs of profound shock.

The second formative event was work experience with a vet. Sutton was convinced that this would be his future career,but the vet was a specialist in racing greyhounds. Sutton was given the job of carrying corpses to the incinerator. “He was very upset by that,” Ann recalls.

It reoriented him to human medicine.

Sutton has been in regular contact with Ann in recent weeks. He has told her that things within the department have been “difficult” but that his public health team has been solidly behind him. He said there were “no problems” in his relationship with Andrews,other than the Premier being “very stubborn” in rejecting Sutton’s advice to get more rest.

Whatever the passing tensions between the two men,Andrews'actions have shown enormous faith in Sutton and the public health team. The Premier has followed their advice to the letter – at considerable political cost,and including when there have been conflicting views among experts.

Sutton’s advice also guided Andrews’ stance in national cabinet in the early days of the pandemic,when he was head to head in pressing an initially reluctant Prime Minister for urgent action.

Asked for comment for this article,Andrews said:“Every step of the way the government’s decisions have been guided by … the Chief Health Officer and his public health team. We’ve had to make some incredibly difficult decisions this year – and we thank Brett and his team for working with us to get Victoria to the other side.”

Sutton has made it clear that he loves his job and wants to keep it. There are big challenges ahead. He has repeatedly spoken about the huge public health challenges that will be caused by climate change,for example.

But the medical community is far from confident that the deeper structural and funding problems with public health in Victoria will be resolved.

The findings of the hotel quarantine inquiry will land just before Christmas. Many expect the DHHS will be split up. The department is in agonies of anticipation.The secretary,Kym Peake,resigned earlier this month.

Perhaps the CHO position will be elevated. Or perhaps Sutton,like his predecessors,will fall victim to the politics.

Last Sunday,Sutton was with the Premier as a further liberalisation of restrictions was announced,including a lifting of the requirement to wear masks outside.

Afterwards there was a jokey interchange between the two men on Twitter about wearing masks in the Bunnings sausage sizzle queue. The Premier tweeted:“Bunnings sausage sizzle line= mask. Onions= on top of the sausage. I can't be clearer than that.”

Sutton responded:“Mask= above nose. Onion= below sausage. Obvs.”

Victoria’s medical community is hoping this is the most serious dispute between them.
