Pathological Demand Avoidance (PDA) is one of those things that people outside the autism world either don’t know about or dismiss as “kids being difficult.” But for anyone who’s lived it, studied it, or worked with PDAers, it’s clear: this profile is its own beast, and understanding it properly can literally change lives.
In Australia, awareness and understanding are still catching up. Take Jenny and her daughter Milly, whose story was recently featured on ABC News. Milly’s extreme responses to everyday expectations, such as standing on desks, fleeing into traffic, and hours-long meltdowns, are textbook PDA. But the key takeaway isn’t the chaos; it’s the misinterpretation. Kids like Milly are often labelled defiant or oppositional when what they’re really experiencing is anxiety triggered by demand itself.
PDA in context
PDA is defined in the National Autism Strategy as:
“An extreme need for control and autonomy driven by high levels of anxiety or an automatic nervous system threat response, which results in demand avoidance, emotional regulation difficulties and a heightened reaction to stress.”
In practice, this means that the usual tools, such as rules, consequences, and even rewards, don’t work. In fact, they often make things worse. For parents, teachers, and carers, that can feel like hitting your head against a brick wall while someone throws chairs at you.
From my own experience as a neurodivergent adult, I can attest that anxiety and executive function struggles can make even simple demands feel impossible. PDAers just take that to an extreme, and often develop incredibly clever coping strategies: distraction, role-play, negotiation, and avoidance that can seem creative, bizarre, or defiant depending on who’s watching.
What’s changing in Australia
The first-ever PDA Conference Australia in Perth this November is a big deal. With hundreds of attendees, speakers including clinicians, teachers, and families, and over 650 tickets already sold, it signals that PDA is finally getting serious attention here. Organiser Heidi Brandis has been building awareness for years, connecting families across Australia and looking to the UK’s more established PDA frameworks for guidance.
Dr Theresa Kidd, a clinical psychologist featured in the conference, emphasises the importance of proper support and recognition:
“Families can feel isolated, judged, and misunderstood… Especially when schools or professionals view the child’s behaviour as simply defiant or oppositional.”
She also highlights that PDAers often bring humour, creativity, and intelligence to the table — qualities that get overlooked when all attention is on the meltdown.
Why understanding PDA matters
Awareness isn’t just academic. For families, it can mean reducing trauma, improving relationships, and even preventing mental health decline. Jenny describes the difference diagnosis and PDA-affirming strategies made in her home as a “light-bulb moment.” Abandoning the typical parent-child hierarchy and reducing pressure allowed Milly to thrive in ways that would have been impossible under traditional approaches.
For educators and professionals, understanding PDA can prevent repeated conflict and mislabelling. And for the neurodivergent community, it’s a reminder that not all resistance is defiance, and that respect, flexibility, and creativity in approach are far more effective than rules and rewards.
TL;DR
- PDA is a distinct profile on the autism spectrum, not simply “stubbornness.”
- Demands can trigger extreme anxiety, so traditional strategies often backfire.
- Clever coping strategies and strengths (humour, creativity, intelligence) are common.
- Awareness in Australia is growing — the first PDA Conference in Perth is a milestone.
- Families and educators benefit immensely from neuro-affirming approaches.
Understanding the “why” behind behaviours is a must. It’s not just about avoiding meltdowns; it’s about creating a space where people with PDA can actually succeed. And that, in my book, is a goal worth pursuing.
