Practitioners with current capacity
Amy Coulter
Positive Behaviour Support Practitioner | Northern Corridor
Amy brings a warm, practical and evidence-informed approach to Positive Behaviour Support. She holds a Master of Clinical Psychology and a Bachelor of Psychology, with more than three years’ experience supporting children with autism and developmental delay.
Based in Perth’s Northern Corridor, Amy supports participants and their teams across Wanneroo, Joondalup, Butler, Clarkson, Landsdale and surrounding northern suburbs. She is a strong fit for referrals involving children and young people who need consistent, practical support across home, school and community settings.
Amy works alongside families, educators, support workers and multidisciplinary teams to turn behaviour support strategies into everyday routines. Her experience includes implementing behaviour support plans, completing functional behaviour assessments and task analyses, using data to monitor progress, and supporting functional communication and reinforcement approaches that are meaningful in real life.
Referrers can expect a patient, collaborative and strengths-based approach. Amy focuses on helping the people around a participant feel clear and confident about what to do, with strategies grounded in dignity, practical fit and least-restrictive support.

Natalija O’Connell
Positive Behaviour Support Practitioner | Swanbourne & Western Suburbs
Natalija is a Positive Behaviour Support Practitioner with experience supporting people with complex behavioural and psychosocial support needs. Her professional background includes work within the justice system and psychosocial disability support, giving her a strong understanding of how behaviour can be influenced by environment, experience, relationships and wider support systems.
She takes a person-centred, practical approach and focuses on understanding what behaviour is communicating rather than simply trying to stop it. Natalija works collaboratively with participants, families and support teams to develop strategies that promote independence, quality of life and meaningful participation in everyday life.
Her experience includes complex presentations, supporting the reduction of restrictive practices, and developing strategies that prioritise dignity, autonomy and human rights. She has a strong interest in neurodevelopmental disability and continues professional development in this area.

Best fit for: Participants with complex behavioural or psychosocial support needs, and families or teams seeking practical, collaborative support that can be used in everyday settings.
Rhea Williams
Positive Behaviour Support Practitioner | Perth Metro & South West
Rhea brings a justice-informed lens to Positive Behaviour Support, shaped by a Bachelor and Master of Criminology and around six years working across justice sector behaviour change programs and NDIS therapeutic and capacity-building supports. Where a behaviour looks like the problem on the surface, Rhea looks for what it’s doing for the person: the function, the environment, and the risk factors sitting underneath it. She holds a rare understanding of the conditions that can increase complex behaviours, but never loses sight of the whole person behind them. Rhea is careful to separate the behaviour from the person, and works from the belief that lasting change comes from understanding someone fully, not just managing what they do.
As a Program Facilitator for therapeutic offending programs delivered in prison, Rhea worked directly with complex and high-risk behaviour, including substance use, violence, and sexual offending, giving her a depth of experience with high-complexity presentations that most PBS practitioners haven’t had to build. She works primarily with people with autism and psychosocial disabilities, and brings the same educational, supportive, and warm approach to every person she works with, whatever the complexity of their presentation. Her plans are built to be realistically implementable, not just technically correct: something support workers, families, and other services can actually pick up and use.
Qualifications: Bachelor of Criminology | Master of Criminology | Diploma of Counselling (in progress)
Registration: NDIS Registered Core Behaviour Support Practitioner
Previous Experience: Program Facilitator, Therapeutic Offending Programs | NDIS Therapeutic Supports | Capacity-Building Supports
Service Areas: Rhea splits her time between Perth Metro and the South West region (including Dunsborough, Busselton, Yallingup and surrounds). If you’re unsure whether she covers your area, get in touch — she’s flexible.
Best fit for: Adults and young people with autism or psychosocial disability, high-complexity or high-risk presentations including justice-involved participants, and teams who need a plan support workers can realistically pick up and use.
Elizabeth Joshua Ampattu
Positive Behaviour Support Practitioner | Southern Corridor
Coming from a speech pathology background spanning over 30 years, Elizabeth recognises behaviour as an individual’s way of communicating their needs, preferences or challenges. Her Positive Behaviour Support approach is grounded in both professional expertise and extensive lived experience working alongside people with disabilities across clinical, community, and disability settings.
Elizabeth combines evidence-based behaviour strategies with genuine empathy, respect and understanding. She takes a proactive, trauma-informed approach that focuses on improving quality of life, facilitating independence, increasing meaningful participation, and promoting choice and control.
Her practice is neurodiversity-affirming, culturally safe and person-centred — recognising and valuing each individual’s unique strengths, communication style, identity, lived experience and cultural background. She works collaboratively with participants, families and support networks to create safe, respectful and empowering environments that uphold dignity, inclusion and human rights.
Qualifications: Master of Science (Speech & Hearing) — All India Institute of Speech & Hearing, University of Mysore | Bachelor of Science in Speech and Hearing — AIISH
