The Role of Peer Support Workers in Mental Health Crisis Teams

Mental health crisis intervention teams are often the first specialist service involved when distress becomes acute. They may respond to suicidal thoughts, severe anxiety, psychosis, substance-related harm, family conflict, or a person’s inability to remain safe at home. Alongside clinicians, peer support workers bring the practical authority of lived experience and a strong focus on dignity, hope, and choice.

In Australia, this contribution matters across metropolitan, regional, rural, and remote settings. A peer worker in Brisbane may support a person navigating an emergency department, while a colleague in regional Queensland may help coordinate care across long distances and limited services. Effective models connect personal experience with clinical governance, cultural safety, and reliable follow-up.

What Peer Support Adds To Crisis Care

Peer support workers have their own lived experience of mental health challenges, recovery, trauma, or caring for someone through a crisis. They use that experience professionally, with training and supervision, rather than presenting themselves as a substitute for a psychologist, nurse, psychiatrist, or social worker.

During a crisis, a peer worker can make the service feel less intimidating. They may explain what will happen next, help a person describe their priorities, sit with them while distress settles, or identify strengths that are easy to overlook. This can reduce feelings of isolation and help restore a sense of control.

Their role also extends to families and carers. Relatives may feel frightened, exhausted, or uncertain about how to respond. A peer worker who has supported a loved one through hospital care can acknowledge those emotions while helping the family communicate safely with the treating team.

Where Peer Workers Fit In A Response Team

Peer workers can be embedded in mobile crisis assessment and treatment teams, hospital liaison services, community mental health teams, telephone support services, and short-term alternatives to inpatient admission. Their responsibilities should be clear from the beginning, including when they lead a conversation, when they escalate risk, and when clinical staff take over.

A typical response may begin with a clinician completing a risk and health assessment while a peer worker builds rapport and explains the process in plain language. The peer worker might then contribute to a safety plan, support shared decision-making, and help arrange practical connections such as housing, alcohol and other drug services, a GP, or culturally appropriate community support.

In Queensland, collaboration between health services, universities, research institutes, and community organisations can help these models move from promising local projects into routine care. The Brisbane Diamantina network provides a relevant example of a translation-focused environment where evidence, clinical practice, and community priorities can be brought together.

A Response Model That Centres The Person

Crisis intervention should begin with immediate safety, but safety is broader than a risk score. It includes a person’s housing, relationships, medication access, physical health, cultural identity, financial pressure, and connection to community. Peer workers can help teams understand these circumstances without reducing the person to a diagnosis.

The following comparison shows how responsibilities can complement each other:

A peer worker may also identify when standard procedures are increasing distress. For example, a person with previous involuntary treatment may be fearful of an emergency department. A calm explanation, a quieter setting, and involvement in decisions can support engagement while the team continues to manage clinical risk.

Safety, Boundaries And Cultural Respect

Peer support requires carefully designed boundaries. Workers should never be expected to disclose personal histories, provide therapy beyond their training, or manage serious risk alone. Clear escalation pathways, clinical supervision, reflective practice, and access to employee wellbeing support protect both workers and consumers.

Confidentiality must be explained in accessible language, including the circumstances in which information may need to be shared to prevent serious harm. Documentation should distinguish the peer worker’s observations and consumer preferences from formal clinical assessment. This clarity strengthens trust and team accountability.

Services also need culturally safe practice. Aboriginal and Torres Strait Islander people may prefer support involving family, Elders, Aboriginal Community Controlled Health Services, or local cultural workers. Approaches should recognise the effects of colonisation, racism, removal from family, and unequal access to care rather than treating culture as an optional addition.

Building A Reliable Peer Workforce

A strong service defines the peer role before recruitment. Position descriptions should specify the required peer support qualification or equivalent training, communication skills, supervision arrangements, and participation in after-hours or outreach work. Recruitment should reflect the communities served, including people from culturally diverse and LGBTQIA+ communities.

Practical design elements include:

• Paid positions with fair employment conditions
• Training in suicide prevention, de-escalation, privacy, and trauma-informed care
• Joint supervision from a peer practice lead and clinical manager
• Clear pathways for escalation, handover, and post-crisis follow-up

Safeguards that support sustainable practice include:

• Routine debriefing after high-intensity contacts
• Flexible rostering and limits on consecutive crisis shifts
• Consumer participation in service evaluation
• Reasonable adjustments for workers managing their own health needs

Partnerships can also support innovation beyond direct service delivery. Health organisations exploring digital tools, referral platforms, or other products may benefit from guidance on bringing devices to market, particularly when new technology affects crisis communication, monitoring, or care coordination.

Measuring Impact And Improving Practice

Evaluation should examine outcomes that matter to consumers, carers, workers, and health services. Possible measures include connection with follow-up care, repeat crisis presentations, use of restrictive practices, time spent in emergency departments, consumer-reported trust, and whether people felt heard in decisions about treatment.

Quantitative data should be paired with interviews and stories. A lower admission rate may look positive, but it should be considered alongside safety, housing stability, access to ongoing care, and the experiences of Aboriginal and Torres Strait Islander consumers. Services should also check whether benefits are consistent across age groups, disability, gender, location, and cultural background.

In Australia, local context shapes results. A model that works in inner Brisbane may need different staffing, transport arrangements, and referral links in Mount Isa, regional New South Wales, or remote communities. Partnerships with Medicare-funded primary care, hospitals, community-controlled services, Lifeline 13 11 14, and local community organisations can make the pathway more practical.

Peer support workers are most effective when they are treated as skilled members of the mental health crisis workforce rather than an informal extra. Health services can begin by mapping current crisis pathways, co-designing the role with people who have lived experience, and funding supervision and evaluation from the outset.
