In the hushed corridors of Canberra, where language is usually cautious and bureaucratic, the top official in charge of Australia’s climate policy has done something unexpected: he has spoken like a person who believes the time for silence is over. Mike Kaiser, secretary of the Department of Climate Change, Energy, the Environment and Water, stood before public servants and told them they cannot sit on the sidelines while bad ideas and false stories spread. His call was blunt. The public service must “take on the public debate” and confront the mis- and disinformation that is stalling meaningful progress, particularly the shift to renewable energy. This is not the usual language of a department head. It is the language of someone who has seen what happens when the public conversation is left only to loud voices and angry algorithms. Kaiser is not asking his staff to become activists or to tweet at critics. He is asking them to do their jobs completely: to explain the evidence behind their policy choices, to answer the fears of citizens honestly, and to stand behind the work they do, not just pass it across to ministers. The stakes could hardly be higher. Australia is trying to expand its renewable capacity in a short period. Every transmission line, every wind farm, every solar field is being debated in living rooms and on social media, often with the same intensity as an election. Yet too often the voices of those who know the details are absent. The result, in Kaiser’s view, is a public debate clogged with myths: that renewables are unreliable, that they will make electricity costlier, that green policy is a fantasy imposed by elites. If the department stays silent, those myths become accepted truths. His words matter not only because he is a senior public servant, but because he is a human being who understands that behind every grid roadmap and emissions target are real families, real farmers and real communities whose lives hang on the outcome. His message is a reminder that public administration is not a bystander to democracy; it is a participant.
Kaiser’s remarks were carefully connected to another voice inside the machinery of government: Jenny Wilkinson, the secretary of the Treasury. Earlier this year, Wilkinson made headlines when she argued that public servants have a duty to explain the evidence base of the policies they spend months, sometimes years, constructing. She acknowledged the danger: some people will always interpret such explanations as advocacy. But she refused to accept that a public servant should therefore say nothing. It is a subtle but important distinction. Explaining why a policy exists, what it is designed to achieve and what data supports it is not endorsing a political party or attacking an opposition. It is the most ordinary kind of honesty: showing your work. Kaiser has now aligned himself with that principle, and he is doing so from the department that is arguably at the centre of Australia’s most contested policy area. In a way, his support is a relief for many public servants, who have watched for years as their analysis was ignored or twisted. It also raises the question: what does “evidence base” actually look like in a world where a fifteen-second video can reach more people than a two-hundred-page report? Kaiser’s implicit answer is that the evidence must be translated into a language people can understand and feel. Simply publishing documents is not enough. A parent in rural Victoria cannot be expected to read the latest energy market report. But they can be asked what they are worried about, and they can be given a straight answer. That is what Kaiser seems to mean by “taking on the debate” — not winning every argument, but showing up respectfully and honestly so that lies are not the only thing people hear. It is a humanising approach to a deeply dehumanised problem. Wilkinson and Kaiser are not proposing that public servants grab megaphones and make political speeches. They are proposing that the machinery of government stop treating the public as a passive audience and start treating them as conversation partners. In an age of institutional distrust, that may be the only way to keep the ties between citizens and the state intact.
To outsiders, it may seem strange that a man with Kaiser’s biography is the one making this case. Most departmental secretaries in Australia are career officials — economists, lawyers, administrators — who have spent decades inside the system. Kaiser is different. He learned politics in the unpredictable world of Queensland Labor in the 1990s. He served as the party’s state secretary from 1993 to 2000, a period of intense factional warfare and electoral challenges. He was briefly a state parliamentarian, but his real strength was always organisational — the strategic side of politics, understanding what moves voters, how messages land and why campaigns succeed or fail. Later, he crossed into the public service and eventually became Queensland’s most senior government official, directing the state bureaucracy through policy reforms and departmental challenges. That career trajectory is almost the inverse of the usual public-service path. And it is precisely that background that makes his current role so interesting. He is not speaking from a textbook about Westminster neutrality; he is speaking from lived experience of what it takes to win a debate. He knows that facts alone do not persuade; stories, trust and repeated human contact matter. He knows that a minister’s press conference can be undermined by a thousand negative online comments within minutes. He knows that fear is a more powerful motivator than data. But he also knows that the public service has a credibility that political parties no longer enjoy. Polls consistently show that Australians trust the public service more than they trust most institutions. That trust is an asset, and Kaiser seems to feel it should be used, not guarded. Too often, the public service treats its credibility like a museum piece — to be protected from the world. Kaiser appears to want to spend some of that trust on the one issue that will define whether his children and grandchildren are safe. His personal history gives him the unusual ability to understand both sides of the public conversation: the political side, which often reduces everything to manipulation, and the bureaucratic side, which often reduces everything to process. In him, those two sensibilities seem to be fused, and the result is a call for a more honest, more courageous public service: one that is unafraid to be seen and heard.
The reason for urgency is obvious. The renewable energy rollout that Australia has embarked upon is not just a construction project; it is an emotional and cultural upheaval. For many communities, the idea of a large wind farm on the horizon or a transmission line through a valley feels like an invasion. It raises legitimate questions about land use, local control, compensation and fairness. But in too many parts of the country, those questions have been drowned out by organised campaigns of misinformation. Online groups, sometimes funded by coal interests and amplified by foreign actors, tell local residents that renewable energy will ruin their health, destroy their landscape and bankrupt them. A few dubious studies are recycled endlessly across social media platforms, each repetition gaining a sheen of truth. And the people with the best knowledge — the engineers, ecologists and economists inside Kaiser’s department — have often been silent, restrained by tradition and protocol. Kaiser’s message is that this must change. A department cannot stand by while its work is caricatured. It cannot pretend that community resistance is simply about not being listened to when those communities are being actively misled. He wants public servants to enter the digital arena, to respond to misleading claims with evidence and empathy, to attend community meetings and listen as much as they explain. But he is not asking them to be pushy. He is asking them to be present. There is a real human dimension to this. People who have lived their entire lives in a rural town often feel a deep connection to the land. They are not stupid; they are worried. When a stranger in a suit arrives with a map and tells them a transmission line will be built across their property, they need more than a legal notice. They need a human relationship. Kaiser’s approach, taken to its logical conclusion, means sending someone to sit at the kitchen table and actually talk — to hear the worries, to acknowledge the uncertainty, to offer clear and honest information about risks and compensation. It is slower, harder and messier than a media release, but it is the only way to rebuild the trust that allows a transition to be seen as a collaboration rather than an imposition.
Of course, there is a deep tension in Kaiser’s approach, and it is important not to romanticise it. The idea of public servants entering political arguments makes many people uneasy, and for good reason. The public service is meant to be apolitical, responsive to whatever government is elected, and loyal to the Crown as much as to the ministry. If a department begins to see itself as the defender of “the truth” in a partisan battle, what happens when a different government comes to power? What if a future government decides that the evidence points in a different direction? Should the department then argue against its own ministers? Kaiser is not careless, and he is not proposing a permanent governmental campaign for one particular policy. He is drawing a line between explaining the evidence and wading into partisan conflict. If a minister makes a decision, the public service implements it. But when the decision is made, it is reasonable for the department to help the public understand why it was made. That is accountability, not advocacy. Still, this is a tightrope. In a society fractured by climate politics, every statement from a climate department will be heard through a filter. The slightest phrase can be clipped, turned into a headline and used as proof that “the bureaucracy is running the country.” Kaiser is aware of this risk; perhaps that is why he frames his call not as an attack on opponents but as a duty to the public. In the long run, a public service that refuses to answer for its own work will inevitably lose its legitimacy. Citizens will no longer believe that reports are based on evidence; they will suspect that every document is a political instrument. A department that does not speak up becomes a repository of alienated knowledge. The answer, Kaiser suggests, is not silence but confident humility: acknowledge the limits of knowledge, admit uncertainties, and still hold the line against outright falsehood. That is a difficult path to walk, but it may be the only path that leaves the public service able to serve everyone, regardless of which party holds power.
Ultimately, Kaiser’s message is about the kind of country Australia wants to be. Democracy does not work when citizens cannot agree on basic facts. It does not work when scientific evidence is treated as just another opinion. And it does not work when the people responsible for designing policy disappear from public life the moment the work is finished. Mike Kaiser, the former political operative turned top civil servant, appears to understand that public administration has a human face. His call for his department to take on the public debate is really a call for courage: the courage to listen, the courage to speak, and the courage to be judged. It is also an invitation. Every public servant has a story and a reason for caring about their work. They are not robots; they are parents, neighbours, citizens. When they step into a community hall to answer questions about a wind project, they are not performing a bureaucratic function. They are embodying the idea that government is made of people. That idea, if restored, could change more than climate policy. It could restore the fragile trust that holds Australian society together. The renewable energy rollout will be won or lost in the spaces where human beings actually meet — not only in parliaments and boardrooms, but in town halls, kitchens, phone calls and comment threads. By asking public servants to take part in those spaces, Kaiser is doing something profoundly human: he is reminding them that they are part of the same public they serve. The fight over Australia’s energy future is not simply a clash of grids and turbines. It is a fight over whether people feel heard, whether they trust the institutions that serve them, and whether they believe the future can be shared. Kaiser’s words, if taken seriously, may help Australians find a way to argue about the future without losing each other in the process.
