The Church of Tuvalu, (Te Ekalesia Kelisiano Tuvalu) has historic ties to the Congregational Church and other churches in Samoa, and has the largest number of followers. All nine island groups have traditional chiefs who are members of the Church of Tuvalu. Most followers of other religions or denominations are found in Funafuti, the capital, with the exception of the relatively large proportion of followers of the Bah Faith on Nanumea Island. Missionaries are present and operate freely.
Australian and Tuvaluan currency are both in use, but transactions over A$1 are always conducted in Australian Dollars. For details of Australian Dollar denominations and exchange rates, see the Australia section.
The Constitution of Tuvalu states that it is "the supreme law of Tuvalu" and that "all other laws shall be interpreted and applied subject to this Constitution"; it sets out the Principles of the Bill of Rights and the Protection of the Fundamental Rights and Freedoms.
