About Sarah
Sarah O'Sullivan is an AASW social worker with six years practising as a therapist. She draws on her long experience in health services and lived experience to guide people through complex mental health challenges. Sarah communicates plainly and keeps sessions focused on what matters now.
Before moving into independent practice Sarah worked across government and non-government services in Queensland. That background gave her practical knowledge of how systems work and where people often get stuck.
Background and approach
She now offers advocacy support alongside therapy, including report writing for court and NDIS when this is appropriate. Sarah pays attention to how relationships and systems shape a person’s difficulties. She uses Systemic ideas to look at patterns between people and across settings.
Attachment-based thinking helps her notice how early bonds affect current reactions and connections. Her clinical focus includes stress, anxiety, addictions, trauma and abuse, parenting concerns and depression. She also works with issues such as abandonment, attachment problems, caregiver stress, and substance use.
Sessions include practical steps like relapse prevention planning and recovery coaching when those are useful. Alongside therapy Sarah can provide specialist documents such as functional capacity assessments using the Allen's model and domestic violence informed mapping using the Safe and Together model. These services are offered as part of a broader plan tailored to each person’s goals.

Online support
Using system-aware and attachment work online
Sarah combines Systemic therapy with Attachment-Based and Client-Centred approaches to guide online work. Systemic therapy looks at patterns between people and settings to uncover practical changes that reduce stress and conflict. Attachment-Based work focuses on how early relationships shape current responses and helps people build steadier ways of relating. Client-Centred therapy puts the person’s goals and pace first, so sessions adapt to what feels most useful.Finding the right approach is part of the process. Sarah will talk with the client about goals, needs and preferences and together they’ll try ways of working that match those aims. That collaborative planning helps decide whether a focus on relationships, emotional regulation or practical relapse planning is best.
Online sessions can be booked as video calls, phone sessions, live chat or text-based messaging. Video is useful for in-depth conversations and reading non-verbal cues. Phone sessions need less bandwidth and can fit a break at work. Live chat or messaging suits brief check-ins or when writing out thoughts helps. These options make therapy more flexible and easier to fit into busy lives.
