Youth Enhanced Support Service (YESS)

Information for health professionals working in South Western Sydney


The Youth Enhanced Support Service (YESS-SWS) provides support to young people 12-25 years old with, or at risk of developing, a severe mental illness. The service aligns with the evidence-based Youth Mental Health Principles recommended by Orygen.

YESS-SWS is commissioned by South Western Sydney PHN and delivered by Parramatta Mission.




YESS-SWS is an early intervention program providing wrap-around supports within a recovery-oriented, strengths-based framework, including:

  • Risk assessment, risk management and safety planning
  • Mental health treatment
  • Family and carer support services
  • Non-clinical wrap around services
  • ​Continual engagement with the young person’s GP


Why has SWSPHN commissioned YESS-SWS?

A severe mental illness can be complex and enduring in its presentation, significantly impacting the young person’s day-to-day functioning. YESS-SWS aims to ensure young people with, or at risk of developing a serious mental illness, have access to quality service and interventions to support them in their recovery and reduce long-term mental ill-health, through an early intervention approach.


The service engages with the ‘missing middle’, those who require a more intensive service than SWSPHN youth mental health primary care services are funded to provide, but who also do not meet the state funded tertiary mental health service criteria. Therefore, YESS-SWS will work closely with headspace centres in Liverpool, Bankstown and Campbelltown, ReFrame in Wollondilly and Wingecarribee and SWSLHD mental health services. 


What services are provided?

The program will support young people across their mental health and psychosocial needs through psychological therapies, service navigation and peer support, delivered in an evidence based, best practice approach.



YESS-SWS is a free service for people who meet the following criteria:

  • Aged 12-25 years old, and
  • With or at risk of a serious mental illness (clinical stages of 2, 3 or 4 based on Orygen’s clinical staging model), and
  • Living, working or studying in the South Western Sydney region comprising of Liverpool, Bankstown, Fairfield, Campbelltown, Camden, Wollondilly and Wingecarribee Local Government Areas.

And either:

  • Transitioning from tertiary mental health services (for example, ICAMHS) delivered by SWSLHD into primary mental health services, or
  • Experiencing emerging symptoms of serious mental illness, including a first episode of psychosis, or
  • Engaged with headspace or ReFrame but requiring more intensive support than these services can offer.

YESS-SWS can accept referrals from young people (self-referral), their family or friend (with the young person’s agreement), GPs, school counsellors and service providers.
