At Supporting Sullen, our mission is simple: to support people and strengthen community. Founded by Steven Arthur, a Behaviour & Wellbeing Consultant who grew up on Norfolk Island, our service is built on a deep understanding of both professional practice and community values.

Steven holds a Bachelor of Psychological Science and a Master of Forensic Mental Health, and has extensive experience working across disability, forensic, and community settings. Steven brings both specialist knowledge and practical, hands-on skills to every person and family he supports.

We provide Behaviour Support and Community Wellbeing services that are person-centred, respectful, and tailored to each individual or family’s needs. Our approach blends evidence-based practice with compassion, ensuring that every person we work with feels heard, valued, and supported.

From behaviour support planning and training to family workshops and practical resources, we are committed to creating positive, lasting change. We believe in walking alongside people, not just providing strategies, but building confidence and connections that make a real difference in daily life.

At Supporting Sullen, we care for orl ucklun — our people, our families, and our community.
