::::::::::All of the above points are less than definitive. There is no ultimate statement and to say that one person or another is the head of state is to construct an argument. There is no Australian law saying who is the head of state, there is no ruling by the High Court, there is no certainty. It comes down to opinions. Strongly held, opinions in some cases, and those holding one opinion often regard those holding a contrary view as deeply and fundamentally wrong. It is not Wikipedia's place to make any final ruling, based on opinions, chains of logic, selective quotes or any other artificial mechanism. The nation is divided in its view, this is easily demonstrated, and we have NPOV to prevent us from promoting any one particular view over another.
