How it works in Northern Territory
The Northern Territory stands apart on rent-increase timing: a landlord can raise the rent once every six months rather than once a year, and only 30 days' written notice is required — the shortest notice and most frequent allowance in the country. Notice can be given by letter, email, or text. There is no cap on the amount, but a tenant can apply to the NT Civil and Administrative Tribunal if they consider an increase excessive.
