Shelter Housing Action Cairns (well known as SHAC) is a non-for-profit organisation located in tropical Cairns, Queensland. In November 1987, SHAC was established after a need was identified during the International Year of Shelter for the Homeless. In May 1988, SHAC commenced providing accommodation and tenancy assistance to the Cairns community for families who were homeless or at risk of homelessness.

For over thirty years, SHAC has grown and developed to respond to the needs of families in Cairns, shaping service delivery to what it is today. Currently, SHAC manages 19 temporary supported accommodation properties, 2 long term community housing properties, and up to 8 transitional housing properties. Staffed by a hardworking team of 17 employees, SHAC delivers wraparound support services and case management to families and individuals through Family Support, Mobile Support, My Money Program, and No Interest Loan Scheme (NILs).
