What it does
The Christmas Island Act 1958 (the Act) performs three core functions: (1) it formally incorporates Christmas Island into the Commonwealth as an external territory; (2) it establishes a streamlined legal and judicial system that applies Western Australian law by default while preserving Commonwealth supremacy; and (3) it supplies machinery for local law-making, parliamentary oversight, court operations, and miscellaneous administrative matters.
Section 5 declares that Christmas Island—defined geographically in s 4(1) as the island at approximately 10°30′S 105°40′E—is accepted by the Commonwealth and shall be known as the Territory of Christmas Island. Section 6 effects a wholesale transfer of pre-existing property, rights, powers, liabilities, and obligations from the United Kingdom, the Colony of Singapore, and the Colony of Christmas Island to the Commonwealth as at the “proclaimed date” fixed under s 2(2). Subsection 6(3) carves out specific exceptions, principally Singapore public loans, pensions for service on the island, Post Office Savings Bank deposits, and Central Provident Fund liabilities. These provisions exhausted the original 1958 purpose of severing imperial ties.
The substantive ongoing work of the Act lies in Part III (Laws and Legislative Powers). Section 7(1) prescribes that, on and after 1 July 1992, the laws in force in the Territory comprise: Commonwealth Acts, Ordinances made under this Act, laws continued by s 8, and “applied Western Australian laws”. Section 8A(1) then applies Western Australian laws (defined in s 8A(6) to include statutes, common law, and equity but to exclude Commonwealth Acts) as laws of the Territory, subject to inconsistency with the Constitution, an Act, or an Ordinance (s 8A(4)–(5)). An Ordinance may incorporate, amend, or repeal an applied WA law (s 8A(2)) or suspend its operation (s 8A(3)). The Minister must table successive lists of applied WA Acts (s 8B), and either House may terminate their application by resolution or by the passage of time under the complex notice-of-motion rules in ss 8C and 8D. Termination has repeal-like effect and can revive earlier laws (s 8C(5)–(6)).
