ICMDA's Oceania region covers the three larger nations of Australia, New Zealand and Papua New Guinea, along with 20 smaller sovereign states and dependent territory islands.

It is a vast area covering covering 88 million square miles of ocean and is dotted with 25,000 islands. However, just Australia, New Zealand and Papua New Guinea have fellowships that are affiliated with ICMDA.

There are 34 medical schools here, serving the region's 42 million people. The major languages are English, French and the various Polynesian languages.

There is a large Christian presence here, particularly in the smaller islands, reflecting its colonial past, but the Christian influence is being eroded by secularism and nominalism. Migration is occurring on a massive scale, with many Pacific Island ethnicities having a larger population abroad than in their traditional homeland.  This places social and economic pressure on the area.

There are very few skilled health professionals in Papua New Guinea, only 6 for every 10,000 people, compared to 143 & 162 in New Zealand & Australia respectively (for every 10,000 people). Most other major islands have between 20-40 health professionals for every 10,000 people.
