Current RMO:

As part of our commitment to training and supporting the next generation of rural doctors, GMC hosts Junior Doctors under the John Flynn Prevocational Doctor Program. These doctors have completed their medical studies in the previous 12-24 months and have provisional or limited registration. You may be offered an appointment to see our current junior doctor using what we call “wave consulting”. This means you will see the junior doctor who will listen to your concerns, assess you and develop a plan of management with you. You will then be joined by the supervising doctor, generally your usual GP, who will ensure you are happy with the plan and complete any further actions you may need. Our junior  doctors also assist us with audit and research projects.
