The continent of Oceania has four regions; Australasia, Melanesia, Micronesia and Polynesia. It is the smallest continent in terms of area, and the second smallest in terms of population (only Antarctica has fewer residents). In fact, many countries have larger populations than the entire continent of Oceania.
Of the few million people who do live in Oceania, around half live in one country: Australia. The vast majority of jurisdictions in Oceania have comparatively small areas and populations.
