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.

None of these divisions has adopted an official flag. However, a 1985 territorial decree permits the official use, alongside the French tricolour and the French Polynesian flag, of the official flag of the archipelago on which the flags are displayed.^[17] Four of the archipelagos have adopted such official flags.^[18] The two that have not are the Leeward Islands and the Windward Islands.
