St John Ambulance Western Australia has bought Perth-based medical centre provider Apollo Health and plans to run its four GP clinics as bulk-billed urgent care centres.

Apollo Health operates four primary health clinics in Cockburn, Joondalup, Armadale and Cannington. From July, St John plans to accept unscheduled care patients at Cockburn, Joondalup and Armadale and St John ambulances servicing Cockburn and Joondalup.
