Inside the CASC Conference Why Australia’s Gender Care Debate Is Intensifying
The room was larger than I expected, and that mattered. When a conference built around scepticism of gender-affirming care draws more than 200 attendees, many of them medical or psychological professionals, it is no longer a fringe side conversation. It is part of Australia’s widening fight over how children and young people experiencing sex or gender-related distress should be treated.
I attended the CASC conference on 9 and 10 October 2026. CASC stands for the Coalition for the Advance of Scientific Care. I had also attended in 2025, though not the Friday night dinner, and I went the first time expecting a small and openly extreme gathering. What I found was more complicated, and in some ways more troubling.
The public language was careful. The stated focus was evidence, safeguarding, families, courts and clinical practice. But inside the event, several comments and emphases left me with the impression of a movement using the authority of “science” to advance a much harder political and clinical position.
This post is a personal account and reflection, not medical advice. Gender care involves complex clinical, legal and ethical questions, and young people and families deserve careful, individual support.
What CASC says it is trying to do
CASC presents itself as a group concerned with the evidence base for gender-affirming healthcare in Australia. Its conference promotion described the 2026 event as a continuation of the 2025 summit, with “international and national experts” examining gender-affirming care as practised by the medical profession in Australia.
The advertised themes included:
the evidence for gender-affirming care
the impact on children, young people and families
recent international developments and court cases
alternative approaches to sex or gender-related distress in young people
The keynote speakers promoted for the event included Stella O’Malley, psychotherapist and founder of Genspect International, Sallie Baxendale, consultant clinical neuropsychologist, Patrick Parkinson, Emeritus Professor of Law at the University of Queensland and a specialist in family law and child protection, and Marcus and Susan Evans, former Tavistock clinicians and gender care practitioners, appearing via Zoom.
On paper, that framing suggests a serious conference about clinical uncertainty, risk, informed consent and the responsibilities of health systems. Those are valid topics. Any area of medicine involving children, identity, mental health, puberty, family conflict and long-term outcomes deserves close scrutiny.
The problem is not that CASC asks questions. The problem is the pattern of the answers it seemed most willing to elevate.
My expectations in 2025 were wrong, but not in the way I expected
When I went in 2025, I expected a small group of obvious extremists. That assumption did not hold. The room included doctors, psychologists, psychiatrists, legal voices and people who clearly saw themselves as defending children from harm.
That made the event more significant, not less.
A movement does not need to look extreme to have extreme effects. It can wear the language of caution, ethics and child protection. It can quote research, invoke international trends and speak in the tones of clinical seriousness. The social power comes from who is in the room and how claims are framed.
By 2026, attendance had grown to more than 200 people. That number matters because it suggests organisation, confidence and reach. It also suggests that the Australian debate is not only being shaped by activists on either side. It is being shaped by professional networks that can influence referrals, public submissions, media commentary, hospital policy and legal argument.
That is why the CASC conference felt like more than an event. It felt like a sign of where the debate is heading.
The word “scientific” did a lot of work
The phrase “scientific care” sounds neutral. It suggests clear evidence, sober judgement and protection from ideology. Most people want healthcare to be evidence-based. Most clinicians do too.
But “scientific” can also become a shield. If one side positions itself as the defender of evidence, the other side is easily cast as reckless, captured or ideological. That framing narrows the debate before it begins.
At the conference, the emphasis on evidence often seemed to point in one direction. Doubt was directed strongly at gender-affirming models of care. Much less doubt appeared to be directed at the assumptions behind watchful waiting, exploratory therapy, or broader claims about social influence and adolescent development.
That imbalance stood out.
Good evidence-based care does not mean selecting only the uncertainties that support your preferred position. It means asking hard questions of every pathway, including the pathway of delayed care, refused care, family-led decision-making and therapeutic approaches that may aim, directly or indirectly, to reduce or suspend a young person’s gender-related distress without affirmation.
Caution can protect. Caution can also harm when it becomes a reason for inaction or blanket suspicion.
The awards and speakers showed the conference’s centre of gravity
One moment that stood out was the recognition of psychiatrist Dr Jillian Spencer. Dr Spencer was suspended from the Queensland Children’s Hospital in April 2023 after criticising the hospital’s gender-affirming care pathway and advocating for a watchful waiting approach. At CASC, she received an award recognising her “courage in speaking up for vulnerable children and defending evidence-based medicine”.
That award revealed a great deal about the event’s moral frame. Dr Spencer was not presented merely as a clinician with a contested view. She was celebrated as a courageous defender of vulnerable children.
That matters because in these debates, the hero narrative is powerful. Once someone is cast as the brave truth-teller, criticism of their position can be framed as censorship or cowardice. It becomes harder to ask whether their preferred model of care has its own risks, gaps and ideological commitments.
Dr Sallie Baxendale also presented on the adolescent brain. That topic is highly relevant. Adolescence involves rapid development, changing identity, risk-taking, emotional intensity and evolving decision-making capacity. Those realities should inform clinical care.
But brain development arguments can also be misused. If adolescent immaturity becomes the main lens, young people’s own accounts of their lives can be discounted too easily. The fact that adolescents are developing does not mean they are unreliable narrators of their distress. Nor does it mean adults automatically interpret that distress more accurately.
The ethical challenge is to hold both truths at once:
young people need protection from rushed or poorly evidenced interventions
young people also need protection from dismissal, delay and adult agendas
A conference that strongly emphasises the first risk but gives less weight to the second risks becoming advocacy with a stethoscope.
Why the Australian debate is intensifying now
The CASC conference did not happen in a vacuum. Australia is absorbing international developments, including legal disputes, shifting policies in some overseas health systems and major reviews of youth gender services, including the UK’s Cass Review released in 2024.
Those developments have changed the tone of the debate. People who were once hesitant to question gender clinics now feel more confident doing so. Governments and health departments face pressure to review guidelines. Media coverage has become sharper. Families are caught between competing claims about safety, evidence and ideology.
Australia’s federal system adds another layer. Health services, hospital pathways and child protection settings vary across states and territories. That can create uncertainty for families and clinicians alike. It also gives advocacy groups more entry points, because policy influence does not need to happen in only one place.
CASC appears to be part of that broader shift. Its language connects local concerns to international networks and disputes. Its speakers bring together clinical, psychological and legal critiques. Its growth from 2025 to 2026 suggests that scepticism of current gender-affirming models is becoming more organised in Australia.
That does not mean every attendee shares the same view. Conferences contain a mix of motives. Some people may be genuinely undecided. Some may be worried about consent, comorbid mental health issues or diagnostic practices. Some may be opposed to gender-affirming care in principle, even if they use softer language in public.
The risk is that these differences blur together under one respectable banner.
The missing centre of the conversation
What felt least present, at least in the parts that shaped my impression, was a sustained sense of the young people who sit at the centre of this debate.
Not as symbols. Not as evidence of harm. Not as case studies that prove one side right. As people.
Some young people who experience gender distress may later understand that distress differently. Some may regret social, medical or legal steps. Some may feel harmed by clinicians who moved too fast. Those stories deserve to be heard without defensiveness.
Other young people experience gender-affirming care as stabilising or life-saving in the plain, everyday sense that it helps them keep living, studying, relating and imagining a future. Some feel harmed by being disbelieved, delayed or forced into frameworks that treat their gender identity as a symptom to be explained away. Those stories also deserve to be heard without suspicion.
A serious healthcare debate needs to make room for both.
What worries me about spaces like CASC is not that they discuss regret, doubt, desistance, comorbidity or safeguarding. Those subjects belong in the conversation. What worries me is when those subjects become the whole conversation, and when the possibility of trans flourishing becomes almost invisible.
If a conference claims to examine care, it should ask what good care looks like for different young people, not only how to stop bad care. Good care might include slower assessment in some cases. It might include family therapy. It might include social support at school. It might include medical pathways for some adolescents after careful assessment. It should never begin from contempt for the young person’s stated experience.
The difference between scrutiny and suspicion
Australia needs better public discussion of gender care. That discussion should be calm enough to admit uncertainty and honest enough to name harm when harm occurs.
Scrutiny asks:
What does the evidence show?
Where is the evidence limited?
Which young people benefit from which interventions?
What safeguards reduce risk?
How should consent work?
How do we measure long-term outcomes?
What happens when care is delayed or denied?
Suspicion asks different questions:
Who is lying?
Who has been captured?
Which clinicians are brave and which are dangerous?
Which young people are confused?
Which parents are ideological?
Which institutions must be exposed?
The CASC conference often sat in the uneasy space between those two modes. Its official framing leaned towards scrutiny. Some of its energy, awards and rhetoric seemed to lean towards suspicion.
That distinction matters because suspicion spreads quickly. Once a whole field is framed as captured, every clinician who offers gender-affirming care becomes suspect. Every trans-affirming parent becomes suspect. Every distressed young person becomes a possible victim of contagion, grooming, ideology or medical fashion.
That is not a careful evidence-based culture. It is a culture of distrust.
What should happen next
The intensifying debate over gender care in Australia needs more than slogans about affirmation or protection. It needs transparent evidence review, better outcome data, careful consent processes, and services that can respond to complexity without turning young people into political battlegrounds.
It also needs humility from every side.
Supporters of gender-affirming care should be willing to talk about uncertainty, regret, assessment quality and the limits of existing evidence. Critics should be willing to talk about the harms of rejection, delay, stigma and blanket scepticism. No one should pretend this is simple.
CASC is important because it shows how organised and credentialed the critique of gender-affirming care has become in Australia. It is also concerning because the authority of science can be used to narrow care as easily as it can improve it.
I left the conference more convinced that the debate is intensifying, and less convinced that the loudest claims to neutrality are always neutral. The real test is not who says “evidence” most often. It is whether the evidence is used to keep young people safe, seen and genuinely cared for.
