The Australian medical education system is historically similar to that of the United Kingdom, but in recent decades, has received influences from the United States and Canada. In contrast to their North American counterparts, Internship and Residency in Australia are pre-vocational terms intended for general clinical rotations so that the junior doctor can gain a broader clinical experience in various medical specialties prior to embarking on a specialist-vocational training program as a Registrar. In the United States, there are no pre-vocational terms, whereby specialty selection during Internship ensures streamlined clinical rotations for that intended specialty pathway, and thereafter, enrolment and progression onto a Residency program towards achieving specialist board certification; thus, Residency in the United States is equivalent to a Registrarship in Australia.
