Ending a Fixed Term Tenancy in the Northern Territory — Landlord Guide

The Automatic Rollover Trap

A fixed-term tenancy in the Northern Territory does not simply end when its term expires. Under section 83 of the Residential Tenancies Act 1999, if the fixed term reaches its end date and neither party has served a valid termination notice, the tenancy automatically converts into a periodic tenancy on the same terms. The tenant stays, the rent continues, and you now need to give 60 days notice to end what has become a periodic agreement.

If you want the tenancy to end at the fixed term's expiry, you must serve a section 90 notice before the deadline passes.

The 60-Day Notice Requirement

Since 2 January 2024, landlords must give at least 60 clear days notice before the fixed term's expiry date for agreements entered into on or after that date. The form is Form RT05, and you tick the section 90 box.

For pre-2024 agreements, the old rule was 14 days before expiry. But most fixed-term leases started before 2024 have already expired or renewed, so the 60-day rule is now the practical standard.

Timing the Notice

The notice must specify the exact date the fixed term ends as the termination date. You count backwards from that date to work out when to serve:

• Take the fixed-term expiry date.
• Subtract 60 clear days (remembering the service date and the expiry date are both excluded from the count under the Interpretation Act 1978 NT).
• Serve the notice on or before the resulting date.

Example: A 12-month fixed term expires on 31 March. You need 60 clear days. Day 60 of the countdown would be 31 March, so Day 1 is 30 January. Serve on or before 29 January (Day 0). If you serve by post, add postal transit time to the calculation and serve even earlier.

Serve late and the notice is defective. The fixed term expires, the tenancy rolls into periodic, and you are back to a 60-day section 89 process.

What You Cannot Do During a Fixed Term

A fixed-term tenancy is a binding contract for its full duration. You cannot terminate it early simply because:

• You want to sell the property with vacant possession
• You or a family member want to move in
• You want to renovate or demolish the building

None of these are early-termination grounds under the NT Act. If you sell a property with an active fixed-term lease, the buyer steps into your shoes as the new landlord and inherits the tenancy until it expires. The only ways a fixed term ends early are by mutual written agreement (section 82), a tenant break-lease claim (capped compensation under section 122), or an NTCAT order for breach or serious damage.

If the Tenant Will Not Leave at Expiry

You have served a valid section 90 notice and the fixed term has ended, but the tenant remains. Because section 83 would normally convert the tenancy to periodic, your timely notice under section 90 prevents that conversion — but you still cannot physically remove the tenant.

File NTCAT Form 1 relying on the section 90 notice and seek a termination order and order for possession. NTCAT can grant possession and, if necessary, the order is enforced through the NT Local Court by a court bailiff.

Planning Ahead

The 60-day window means you need to be thinking about the end of a fixed term at least three months before expiry — earlier if you are an interstate owner who needs to coordinate with a local contact for personal service. The NT Ending a Tenancy Guide includes a timeline planner alongside the clear-days worksheet to help you work backwards from any expiry date.
