Wayss beginnings can be traced back to the 1970s, when various charity groups sought to address a growing need for emergency accommodation services in the Westernport region of Victoria. Among them was the Westernport Youth Refuge, which evolved to become an integral part of Wayss, and is now known as Wayss Emergency Youth Accommodation (EYA).
Wayss Ltd was officially established in September 1997, after the Regional Housing Council ceased. A board of directors formed, which then appointed a chief executive officer. Among the initial services included transitional housing for families, women and children escaping family violence. Also, services for single adults and young people.
Over the decades, Wayss has implemented and operated numerous housing, homelessness and family violence services. Today, Wayss provides services across the Local Government Areas (LGAs) of Greater Dandenong, Casey and Cardinia.
