INTRODUCTION:
People experiencing homelessness face profound barriers when accessing primary healthcare, contributing to avoidable illness, hospital demand and premature mortality. Nurse-led inreach and outreach models can improve health equity, particularly when informed by lived experience and grounded in the social determinants of health. Since 2023, OneBridge has conducted ongoing action research evaluating the impact of the MartMolly Method, an equity-informed nursing approach co-developed with people experiencing homelessness to translate social justice principles into clinical care. This model aligns with Sustainable Development Goal 3 (Good Health and Wellbeing) and Goal 10 (Reduced Inequalities) by strengthening access to care for excluded populations.

METHODS:
A continuous action research cycle was undertaken across 29 community and housing locations in Queensland and New South Wales. Nurses provided trauma-aware primary care, mental health support, child health checks and care navigation for women, youth and culturally diverse groups. Data collection included service activity metrics, and thematic analysis of client and partner feedback.

RESULTS:
Over 10000 health engagements were delivered across two years, with 67% of people experiencing or at risk of homelessness returning for regular care. 68% presented with mental health concerns and 41% required housing-related support. Care coordination resulted in 350 successful linkages to primary and specialist care including General Practitioners, mental health teams and alcohol and other drug services. Partner organisations reported increased tenancy sustainment and reduced crisis escalation. Clients described care as compassionate, safe and relationship-driven.

CONCLUSIONS:
Nurse-led inreach and outreach informed by action research and lived experience improves equitable access to healthcare and continuity of care for people experiencing homelessness. Embedding the MartMolly Method within community nursing practice offers a scalable and sustainable strategy to advance health equity and accelerate progress toward Australia’s public health goals and the United Nations SDGs
