St John WA is a charitable, non-profit, humanitarian organisation teaching first aid to the community, delivering the State’s ambulance service with sub-branches, including Harvey.

In 2021, Harvey opened a new Sub Centre built by Resicom. Besides emergency services, the state-of-the-art facility provides purpose-built on-site accommodation, training and specialised debriefing areas to accommodate the increasing number of St John WA volunteers in Harvey.

St John WA attends over 1,300 call-outs each year in Harvey and surrounding areas, with 42 volunteers dedicating their time and skills to the local community. After 88 years of volunteer service, since 2023, the Harvey Sub Branch has operated a hybrid paramedic model with paid paramedics working alongside volunteers.
