Australian External Territories are regions that are under the jurisdiction of Australia but are not part of the Australian mainland or its states. These territories include places like Norfolk Island, Christmas Island, and the Cocos (Keeling) Islands. They have unique governance structures and may have different laws compared to the mainland. These territories are often remote and have small populations. They are important for Australia's national interests, including environmental conservation and maritime security. The Australian government provides services and support to these territories, ensuring that residents have access to essential resources and infrastructure.
