the supreme court decides
There is no specific limit required for either the Northern territory or the Australian Capital Territory to become a state. For either territory to become a state would be a fairly straightforward matter. 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 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.
It was a territory.
It's a state, not a territory
There is, theoretically, no lower limit of people for a territory to become a state. In Australia, the Northern Territory could become a state, and it would be a fairly straightforward matter. 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.
No, it is a Territory. A territory may aspire to become a state but it depends on many factors.

The Judicial Branch of the government, which is divided as various courts on the state level and as the Supreme Court on the Federal level, decides whether laws are Constitutional or not.
The legislature decides whether a bill is acceptable to become a law when they decide whether or not to make it. In the process of becoming a law, the president or governor of the state has the option to veto a bill. Once it is law, judges can refuse to enforce it, and if it is unconstitutional the State or US Supreme Court can nullify it.
A territory becomes a U.S. state when it reached a total population of 60,000 people.
