Objectives To explore the increasing numbers of emergency medicine (EM) registrars that obtained their primary medical degree from UK or Irish universities, who work in emergency departments (ED) throughout Australia and New Zealand.

Methods The Victorian Emergency Registrar Study was published at the Australasian College for Emergency Medicine (ACEM) annual scientific meeting in Adelaide in November 2013. As a follow on, ACEM provided the authors with data regarding country of primary degree for international medical graduates (IMG) working as registrars in Australasian EDs.

Results UK and Irish EM registrars make up the largest proportion of IMGs working in Australian and New Zealand EDs. These figures have increased from 34% in 2008 to 45% in 2013. In 2013, there was the highest yearly intake of UK and Irish ED IMG registrars, representing 41% of registrars joining the Australasian EM training programme. Current data show that >25% of all ED registrars working in Australasian EDs studied for their primary medical degree in a university either in Ireland or the UK.

Conclusions While there have been anecdotal reports of increased outflow of junior EM doctors from the UK and Ireland, we provide quantitative data on the extent of the recent (5-year trend data) emigration of UK/Irish EM trainees to Australia and New Zealand and discuss the impact of this on both the UK/Irish and Australasian health systems.
