The Quiet Rule Change That Means Every Australian Psychologist Now Has to Understand Your AuDHD Brain

On a Monday in December, almost no one noticed, a regulator changed the floor under every psychology room in the country. From 1 December 2025, the Psychology Board of Australia’s first-ever binding Code of Conduct and updated core competencies came into force, and tucked inside the legalese was something AuDHD Australians have been waiting on for a very long time: the word neurodiversity, written in as a minimum standard of care.

If you have ever paid $220 for a session with a psychologist who gently suggested you “try harder” to make eye contact, or who told you your ADHD couldn’t be “that bad” because you’d made it to the appointment on time, this quiet regulatory shift is about you. It does not fix the system. But it changes the rules of what counts as competent practice, and that matters more than it sounds.

The situation: a therapy lottery that has failed too many AuDHD Australians

There are roughly 650,000 people in Australia living with co-occurring autism and ADHD. Many of them arrive at a psychologist’s office later in life, often in the wake of burnout, a child’s diagnosis, or a chronic pattern of “working twice as hard for the same result.” Once there, they enter what clinicians themselves describe as a lottery.

Medicare will, under a Mental Health Treatment Plan, rebate up to ten psychology sessions per calendar year, at $98.95 for a general psychologist and $145.25 for a clinical psychologist as of July 2025. Most psychologists charge well above those amounts, so a gap fee of $80 to $150 per session is typical. Diagnostic assessments themselves are not covered at all, and a full dual AuDHD assessment in the private sector commonly runs between $1,500 and $3,500. That is a great deal of money to spend on a professional who may or may not understand your brain.

And understanding has been patchy. Until now, nothing in the national psychology competencies required a practitioner to know what neurodiversity was, let alone how to work with an autistic or ADHD client without unintentionally causing harm. Research published in 2025 found that autistic participants linked the exhaustion of masking directly to suicidality and unhealthy coping, and that suppressing stims and other self-regulatory behaviours in therapy can worsen the very distress the person came in to address. Goals that centre on “appearing more neurotypical” have, in other words, been quietly hurting people for years.

The complication: the old rulebook did not mention neurodiversity at all

The Psychology Board of Australia (PsyBA) sits under the Australian Health Practitioner Regulation Agency (AHPRA) and sets the minimum standards that every registered psychologist in the country must meet. Before December 2025, the board had no code of conduct of its own, only a shared multi-profession code. Its competencies focused on five domains of diversity, none of them explicitly neurological.

That is the gap the new rules close. The updated professional competencies, which came into effect on 1 December 2025, now reference at least seventeen areas of individual and cultural diversity, and neurodiversity is one of them. Most significantly, Competency 7 — the one that governs how a psychologist must respond to client diversity — now requires every registrant to understand and apply “neurodiversity, strengths-based, trauma-informed and positive approaches to supporting people with developmental disability.” It further requires them to demonstrate the ability to adapt practice and make reasonable adjustments, including the use of alternative and augmentative communication.

For the first time, affirming neurodivergent ways of being is not a bonus. It is the registration floor. The Australian Psychological Society has told members that the change applies regardless of setting: whether you work in a hospital, a school, a prison or a private clinic, you are now professionally accountable for providing care that is informed by a neurodiversity framework.

This is not a polite nudge. AHPRA is a regulator. Failure to meet competencies can, in principle, be grounds for a notification, a performance audit, or in serious cases a sanction. In practice, the enforcement pathway for “my psychologist still treats my autism like a defect” remains untested — but the standard it would now be tested against has shifted meaningfully in the client’s favour.

The resolution: what affirming care actually looks like, and what is still missing

A 2025 scoping review published in the journal Neurodiversity by Wagland and colleagues synthesised twenty-six studies involving 1,151 participants on what actually constitutes neurodiversity-affirming care for autistic children. The findings were remarkably concrete. Affirming practice means adapting the environment to the child’s interests rather than demanding the child adapt to a neurotypical environment. It means supporting neurotypical peers to engage with autistic children, not the other way around. Crucially, it means eliminating goals that are aimed at masking autistic behaviours — a direct repudiation of decades of intervention logic.

The same principle, applied to adults, reframes AuDHD therapy goals entirely. Rather than “reduce stimming” or “make better eye contact,” an affirming psychologist helps a client reduce the harm of masking, build sensory and executive scaffolding, and develop a narrative that makes sense of a life lived in two nervous systems that rarely cooperate. A growing body of research suggests this matters. Identity-affirming diagnosis, where the clinician validates rather than minimises a client’s self-understanding, has been associated with reduced depression, anxiety and self-harm in neurodivergent adults.

The evidence, however, is not settled. Systematic reviewers have pointed out that “neurodiversity-affirming” is a philosophy, not a manualised treatment. There is still very little head-to-head research comparing affirming therapy to traditional models in adults, and the field lacks validated outcome measures for goals like “reduced masking” or “increased self-advocacy.” The new PsyBA standard will force a generation of Australian practitioners to grapple with that evidence gap, which in turn will drive the research. In the meantime, thoughtful clinicians — including Dr Melanie Heyworth and the team at Reframing Autism, one of the country’s loudest voices for affirming practice — are already writing the curriculum that many psychologists will quietly be learning from this year.

Three caveats are worth sitting with. First, the rule is national, but the market is not: in regional Australia, finding any psychologist remains difficult, let alone an affirming one with AuDHD experience. Second, Medicare still treats psychology as a short course of CBT for a discrete diagnosis, not an ongoing relationship with a neurodivergent brain; ten rebated sessions a year remains the structural bottleneck. Third, diagnostic assessments sit outside the rebate system entirely, which means the most expensive and consequential appointment an AuDHD person will ever have with a psychologist is also the one most vulnerable to a poor match.

Why this still matters

For an AuDHD Australian reading this, the practical takeaway is modest but real. When you next look for a psychologist, you are no longer asking a favour when you ask whether they practise in a neurodiversity-affirming way. You are asking them to confirm that they meet the national competency standard set by their own regulator as of December 2025. You can ask how they understand neurodiversity, what they do differently with autistic and ADHD clients, and how they handle goals that touch on masking. Silence, deflection or the word “disorder” said without context are now meaningful clinical signals.

And for policymakers, clinicians and the advocates who have spent years arguing that “trying to look less autistic” is not mental health care, this is the moment the argument stopped being contested and started being regulated. The floor has been raised. The work now is to lift the rest of the building — Medicare rebates that match real care, a workforce trained to the new standard, and a diagnostic pathway that does not cost the price of a small car — up to meet it.

The rule change was quiet. The consequences do not have to be.
