(The United Nations has its own geopolitical definition of Oceania, but this consists of discrete political entities, and so excludes the Bonin Islands, Hawaii, Clipperton Island, and the Juan Fernández Islands, along with Easter Island.) Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia and New Zealand, which rank high in quality of life and human development index, to the much less developed economies that belong to countries such as Kiribati and Tuvalu, while also including medium-sized economies of Pacific islands such as Palau, Fiji and Tonga. The largest and most populous country in Oceania is Australia, with Sydney being the largest city of both Oceania and Australia. In the 1950s Indonesia and Philippines were removed from Oceania and added to Asia; this resulted in Oceania as a "great division" of the world being replaced by the concept of the continent of Australia.. In some countries (such as Brazil) however, Oceania is still regarded as a continent (Portuguese: "continente") in the sense of "one of the parts of the world", and the concept of Australia as a continent does not exist.']}}]}, {'provenance': [{'wikipedia_id': '22621', 'title': 'Oceania', 'section': 'Section::::Abstract.', 'start_paragraph_id': 1, 'end_paragraph_id': 1, 'meta': {'evidence_span': ['Oceania (, , ) is a geographic region which includes Australasia, Melanesia, Micronesia and Polynesia.
