Two paid paramedics will now be based in Harvey in a bid to bolster ambulance services in the town.
Under the State Government initiative, the Harvey sub-centre will also operate a new hybrid paramedic model, with the new professional paramedics, set to start on Sunday.
The St John sub-centre on Uduc Road has been run by volunteers for the past 88 years.
It is hoped the new hybrid model will help improve ambulance response times and provide more support to the local volunteer base and broader community.
"The Cook Government ensuring paid paramedics are deployed to Harvey for the very first time is a huge boost for our community," Murray-Wellington MLA Robyn Clarke said.
"The sub-centre will also transition to a hybrid model that will provide even more support to our highly dedicated volunteer ambulance officers."
The additional paramedics have been funded as part of the State Government's modernised contract with St John WA.
Under the new contract, Geraldton has already welcomed four paramedics with Margaret River and Esperance set to join in the coming months.
