The Federal Government is the overriding authority in Australia that determines if the Northern Territory (or any other territory) were to become a state.
Australia's constitution of 1901 did (and does) allow for the admission of new states into Australia. Section 121 of the constitution states that all that is required for a new state (or, in this case, for a territory to be declared a state) is for the Federal Parliament to agree. This even means that the Parliament could admit the Northern Territory as a state whether or not the NT agreed to it.

The process by which territory can become a state in the United States is governed by the Northwest Ordinance of 1787, which established a framework for the admission of new states. This law outlines the requirements for population, governance, and boundaries, stipulating that a territory must have a certain population and form a constitution before applying for statehood. Additionally, the U.S. Congress must approve the admission of the new state. This process has been foundational in expanding the United States westward.
