Regardless, both MBBS and MD awarded at any Australian medical school qualifies a person to be registered with the Medical Board as a medical practitioner and allow the graduate to be customarily addressed by their prefix title of 'Doctor (Dr.)'. It is also worthwhile to note that while the colloquialism of the term 'physician' in the United States is used to broadly refer to any type of medical practitioner, in Australia and the United Kingdom 'physician' typically refers to a medical practitioner who specialises in the field of internal medicine / general medicine or its sub-specialities. In order to avoid confusion given the wide interpretation and availability of those who utilise the prefix of 'Doctor (Dr.)' in other professions, the Medical Board and relevant federal and state legislation has chosen to refer medical doctors formally as medical practitioners in Australia.
