Peer support worker vs mental health worker: what’s the difference?

If you’re thinking about a career in mental health, you’ve probably come across two roles that sound similar but are actually quite different: peer support worker and mental health worker.

Both are essential. Both make a genuine difference in people’s lives. But they approach the work from different foundations, require different qualifications, and suit different people. Understanding the distinction will help you choose the path that aligns with your background, your strengths, and the kind of impact you want to make.

This guide breaks down the key differences so you can make an informed decision.

Two paths into mental health — which one suits you?

Australia’s mental health system relies on a range of professionals working together, and peer support workers and mental health workers are two of the most important roles in that mix.

Peer support workers draw on their own lived experience of mental health challenges — either as a consumer (someone who has personally navigated mental health challenges) or as a carer (someone who has supported a family member or loved one through mental health challenges). Their lived experience is their primary credential, and their role is built on shared understanding, hope, and recovery-oriented practice.

Mental health workers draw on clinical and support training to assist people experiencing mental health challenges. They work within structured clinical frameworks, supporting assessment, case management, crisis intervention, and care coordination. Lived experience is welcomed but not required for the role.

Both roles are valued. Both are needed. They complement each other, and many mental health services employ both as part of the same multidisciplinary team.

Peer support worker vs mental health worker at a glance

This comparison table covers the key differences between the two roles. Use it as a quick reference, and read on for a deeper dive into each area.

What does a peer support worker do?

A peer support worker uses their own lived experience of mental health challenges to professionally support others navigating similar experiences. The role is grounded in the idea that shared understanding creates a unique kind of connection — one that complements clinical care but can’t be replicated by it.

Core responsibilities include:

• One-on-one peer support sessions based on shared experience and active listening
• Facilitating peer-led support groups and recovery education programs
• Collaborating on recovery and wellness planning
• Advocating for people within the mental health system
• Building community connections and reducing isolation
• Working alongside clinical staff as part of a multidisciplinary team

What makes this role distinctive is the source of its authority. A peer worker’s credibility comes from lived experience, not from clinical expertise. When they say “I understand,” they mean it literally. For people who distrust clinical services, or who feel that no one truly understands what they’re going through, that credibility is transformative.

The peer support workforce is growing rapidly in Australia. Victoria’s Royal Commission into Mental Health recommended a significant expansion of the peer workforce, the NDIS is funding peer support as a service for participants with psychosocial disability, and hospitals are embedding peer workers in both inpatient and outpatient teams.

For a deeper look at the day-to-day role, see our guide on what a peer support worker does. You can also read about why lived experience is valued as a professional credential.

What does a mental health worker do?

A mental health worker provides practical support, case management, and crisis intervention for people experiencing mental health challenges. They work within clinical frameworks and often focus on assessment, support planning, referral coordination, and assisting people to access the services they need.

Core responsibilities include:

• Supporting mental health assessments and intake processes
• Developing and implementing support plans
• Providing crisis intervention and de-escalation
• Case management and service coordination
• Working with diverse populations in a range of settings
• Supporting people with daily living, social participation, and community access

Mental health workers typically operate within a more structured clinical environment. They may work in inpatient hospital units, community mental health teams, residential rehabilitation services, or NDIS settings.

It’s worth noting that some mental health workers do have lived experience of mental health challenges, but it’s not a requirement for the role. Their professional practice is grounded in clinical training and learned frameworks, regardless of their personal background.

Salary comparison

Both peer support workers and mental health workers earn competitive salaries within the community services sector. Most roles are covered by the Social, Community, Home Care and Disability Services (SCHADS) Award, which sets minimum pay rates.

Source: Seek.com.au and SCHADS Award schedules, 2025–2026. Salaries vary by state, setting (government vs NGO vs private), and individual experience.

Government and hospital-based roles tend to sit at the higher end for both career paths. Community organisations and NDIS providers may offer slightly lower salaries but often provide greater flexibility and variety in the work.

The salary difference between the two roles is relatively small, and both offer genuine career progression. Over time, senior roles in either pathway can reach AU$90,000 or more, particularly in government, hospital, or coordination positions.

Which career path is right for you?

Peer work might be right if…

• You have lived experience of mental health challenges — your own or as a carer — and you want to use that experience professionally
• You believe that shared understanding is one of the most powerful forms of support
• You value a mutual, non-hierarchical relationship with the people you support
• You’re drawn to recovery-oriented, strengths-based practice that focuses on hope and possibility
• You want a career where your personal story is your greatest professional asset

Mental health work might be right if…

• You’re passionate about mental health support but don’t have (or don’t wish to draw on) personal lived experience in a professional context
• You’re interested in clinical support frameworks, assessment, and structured case management
• You want a broad foundation that can lead to further clinical study — such as a Diploma of Mental Health, social work, psychology, or a Diploma of Counselling
• You prefer a more structured, clinical approach to support work

Both paths are valid, both are needed, and both make a genuine difference. Some people even pursue both qualifications over time, combining the unique strengths of lived experience with clinical training to become exceptionally well-rounded practitioners.

The decision isn’t about which role is “better.” It’s about which role fits your background, your strengths, and the kind of contribution you want to make.

Whether you’re drawn to peer work or mental health support, your decision to enter this sector matters. Explore Hader’s Certificate IV in Mental Health Peer Work to see if it’s the right fit for you.

Frequently asked questions

What is the difference between a peer worker and a support worker?

A peer worker draws on their own lived experience of mental health challenges to support others navigating similar experiences. A support worker may or may not have lived experience and works within clinical or support frameworks to provide practical assistance, case management, and care coordination. Both roles are valuable, but they approach the work from different foundations.

What qualifications do you need to be a mental health worker?

The standard entry-level qualification for mental health work in Australia is the CHC43315 Certificate IV in Mental Health. This is a nationally recognised vocational qualification — you don’t need a university degree. From there, you can pursue further study through a Diploma of Mental Health or Diploma of Community Services to expand your career options.

Can you be a mental health worker without a degree?

Yes. The Certificate IV in Mental Health is a vocational qualification, not a university degree. It provides the training and workplace skills needed for entry-level mental health support roles. Many successful mental health workers build their entire career from this starting point, progressing to senior roles through experience and optional further study.

What does a peer worker do in mental health?

Peer workers provide one-on-one support, facilitate peer-led groups, help with recovery planning, advocate within the mental health system, and build community connections for the people they support. Everything they do is grounded in their own lived experience. For a detailed breakdown, see our article on what a peer support worker does.

Is peer work the same as support work?

No. Peer work is a distinct discipline built on lived experience. While both peer workers and support workers provide assistance to people with mental health challenges, peer work is fundamentally defined by the shared experience between the worker and the person they support. It’s a different relationship dynamic, a different qualification pathway, and a different approach to care.

Can I switch between the two roles?

Yes. Many people move between or combine elements of both career paths over time. Someone who starts as a mental health worker might later formalise their lived experience through the Certificate IV in Mental Health Peer Work. Similarly, a peer worker might pursue further clinical training to broaden their skill set. The skills from either pathway are transferable and complementary.
