Upon completion of the prescribed specialty training program by the relevant medical specialty college, doctors are awarded a fellowship of that college and eligible to register and be recognised as a specialist with the Medical Board; paying annual fees to both the Medical Board and Specialty College for their specialist registration. These clinicians are considered to have satisfied all the necessary education and training requirements to become qualified for that specialty. Those with specialist registration are allowed to practice independently and unsupervised in their area of expertise, which in effect allows them to pursue private practice. Specialist clinicians are eligible for an unrestricted Medicare provider number that allows clinicians to bill rebates from Medicare for services delivered to patients, privileges for hospital admissions and private health fund billings, where most patients in Australia are a mixture of publicly covered Medicare and privately insured through a health fund. Whilst most specialist clinicians take the opportunity to pursue private practice, many of them (with the exception of a majority of GPs) continue to work at least part-time as salaried employees in the state public hospitals. There is also an opportunity for specialists partake in hospital administration to take-up committee or managerial positions, such as director of their department or the hospital or health service, as well as being actively involved in the education and supervised training of their junior colleagues.
