Monarchies in Oceania

There are presently six monarchies in Oceania; that is: self-governing sovereign states in Oceania where supreme power resides with an individual hereditary head, who is recognised as the head of state. Each is a constitutional monarchy, wherein the sovereign inherits his or her office, usually keeps it until death or abdication, and is bound by laws and customs in the exercise of their powers. Five of these independent states share Queen Elizabeth II as their respective head of state, making them part of a global grouping known as the Commonwealth realms; in addition, all monarchies of Oceania are members of the Commonwealth of Nations. The only sovereign monarchy in Oceania that does not share a monarch with another state is Tonga. Australia and New Zealand have dependencies within the region and outside it, although four non-sovereign constituent monarchs are recognized by New Zealand and France.
