Australian External Territories in the context of "Norfolk Island"

An economic and monetary union (EMU) is a type of trade bloc that features a combination of a common market, customs union, and monetary union. Established via a trade pact, an EMU constitutes the sixth of seven stages in the process of economic integration. An EMU agreement usually combines a customs union with a common market. A typical EMU establishes free trade and a common external tariff throughout its jurisdiction. It is also designed to protect freedom in the movement of goods, services, and people. This arrangement is distinct from a monetary union (e.g., the Latin Monetary Union), which does not usually involve a common market. As with the economic and monetary union established among the 27 member states of the European Union (EU), an EMU may affect different parts of its jurisdiction in different ways. Some areas are subject to separate customs regulations from other areas subject to the EMU. These various arrangements may be established in a formal agreement, or they may exist on a de facto basis. For example, not all EU member states use the Euro established by its currency union, and not all EU member states are part of the Schengen Area. Some EU members participate in both unions, and some in neither.

Territories of the United States, Australian External Territories and New Zealand territories each share a currency and, for the most part, the market of their respective mainland states. However, they are generally not part of the same customs territories.

000 or Triple Zero is the primary national emergency telephone number in Australia and the Australian External Territories. Triple Zero calls are initially answered by a Telstra Emergency Access Service Point, then transferred to the requested state and territory emergency services organisations. The Triple Zero system is overseen by the Australian Communications and Media Authority (ACMA) and is intended only for use in life-threatening or time-critical emergencies that requires police, fire or ambulance.

When called on a mobile or satellite phone, the international standard emergency telephone number 112 will be redirected to Triple Zero (000). Other numbers including 911 may be answered, though this is strongly discouraged by the government. For people with a speech or hearing impairment, 106 can be called from a telecommunications device for the deaf (TDD) textphones. 000 is the only emergency number that can be dialled from fixed lines including public payphones. No SIM card or calling credit is required to call emergency services, and national 'camp-on' arrangements mean that calls to Triple Zero will be passed through any available mobile network.
