Our Practitioners
Meet the team behind Behaviour Bridge. We are not just report writers — we are experienced practitioners who have worked on the frontline of complex disability support. We know what it takes to manage high-risk behaviours in the real world.
Julianne Shepley
Positive Behaviour Support Practitioner | Founder
Julianne brings an unusually analytical lens to Positive Behaviour Support — one shaped by her background in both Psychology and Criminology and Justice. Where others see a behaviour, Julianne sees a pattern: the antecedents, the function, the systemic factors, and the risk trajectory. That forensic way of thinking is what makes her particularly effective with the cases most providers won’t take on.
With 5 years of experience in the disability sector, Julianne specialises in the most complex end of the caseload — severe aggression, self-injurious behaviour, and situations involving large support teams, restrictive practices, and significant risk of harm to the person or others. She has extensive experience working alongside justice-involved individuals and those transitioning out of the prison system, where the intersection of trauma, behaviour, and systemic disadvantage demands a practitioner who can hold complexity without simplifying it.

Practitioners with current capacity
Adriana Bitca
Positive Behaviour Support Practitioner | Northern Corridor
Adriana brings a uniquely versatile, creative lens to Positive Behaviour Support, built on over 10 years of dedicated experience working with children. Her expertise is rooted in evidence-based psychological training and spans across disability support within clinical, creative and educational settings. Navigating complex comorbidities for participants mainly aged 5 to 18, Adriana’s practice frequently addresses Autism, PDA profiles, ADHD, trauma, sensory processing differences and psychosocial disabilities such as anxiety and depression.
Having had extensive experience creating and implementing care plans within a primary school, Adriana knows the education system inside out. This allows her to successfully collaborate with school staff and design plans that are realistically implementable. Additionally, her professional training and acting background provides her with mastery over body language, use of voice and understanding of how emotions live in the body. It allows her to read subtle sensory shifts before a meltdown occurs, model co-regulation during high-intensity behaviours and use improvisation to build authentic rapport with young people through fun and play on their level.

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.

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 (Corrective Services) | 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.
