This article is a gallery of the flags of the principal subdivisions of the countries and territories of Oceania. For purposes of this article, Oceania is taken to comprise Australasia, Melanesia, Micronesia and Polynesia.
The principal subdivisions are generally the ones that are identified as first-order subdivisions under the ISO 3166-2 coding scheme. If a country has no such first-order subdivisions, but has second-order subdivisions that have their own official flags, then the flags of those second-order subdivisions are given here.
This gallery includes only current official flags. For historical or non-official flags of any particular country or territory (if any), see the main article for that country or territory.
Unless indicated otherwise, information on each country has been taken from the World Factbook, as updated through July 11, 2016 (for which see the External Links section, below).
Australasia
Australia
Australia comprises six states and two territories, as well as several dependant islands located in the Indian and Pacific oceans.
The official flag for each of the six states consists of the Australian national flag, but with the stars removed and replaced with the state's coat of arms.
Most of the dependent areas (sometimes called the "external territories") have no official flag of their own and instead use the Australian national flag. Three external territories do have their own official flags–Christmas Island, Cocos (Keeling) Islands, and Norfolk Island.

New Zealand
New Zealand has sixteen first-level administrative subdivisions. Eleven of them are governed by regional authorities; the other five are governed by unitary authorities (which combine the roles of regional and territorial governance). The Chatham Islands lie outside any of the sixteen regions, but collectively possess some of the governing authority of a region. Most of these seventeen authorities have not adopted official flags.
The Realm of New Zealand includes two non-self-governing territories, one of which (Tokelau) has its own official flag. The other, the Ross Dependency, does not. It also includes the two island nations that are in free association with New Zealand–the Cook Islands and Niue. Their official flags are shown here.

French collectivities in Melanesia
One of France's overseas regions is located in Melanesia. This region is New Caledonia, which is a special-status collectivity of France. It has a flag that shares its official status with that of the French tricolor.
