How to Serve a Tenancy Notice in WA: Approved Methods and Common Mistakes

A perfectly drafted notice of termination becomes worthless if it is served incorrectly. In Western Australia, the Residential Tenancies Act 1987, the Interpretation Act 1984, and the Electronic Transactions Act 2011 define exactly three lawful service methods. Anything outside those three means the notice was never legally served — and the Magistrates Court will dismiss your possession application.

Method 1: Personal Delivery

Hand the notice directly to the tenant. If the tenant is not home, you can give it to a person who appears to be over 16 years of age and resides at the premises — or to the person who usually pays the rent if that is someone else.

Personal delivery takes effect immediately. The notice period starts counting the next day.

Proof: Note the date, time, and who received the notice. If there was a witness present, record that too. There is no prescribed form for proof of personal service, but a written record is essential if the matter goes to court.

Method 2: Ordinary Prepaid Post

Send the notice by Australia Post standard mail to the tenant's usual or last known residential address. The key word is "ordinary" — this means regular prepaid mail, not registered, not express, not courier.

Do not use registered post. If the tenant refuses to sign for it or does not collect it from the post office, service is deemed to have never occurred. Ordinary post avoids this problem entirely — it is deemed received after a reasonable postal transit period without any action required by the tenant.

Add Australia Post transit days (business days) to the front of your notice period calculation. The notice period does not start until the letter is deemed received.

Proof: Keep the Australia Post receipt showing the date of posting. If you can get tracking, keep the tracking record. A photo of the addressed envelope with postage is also useful.

Method 3: Email

Email is a valid service method — but only if the tenancy agreement contains an express written clause consenting to electronic service. For agreements on the Form 1AA template, there is a specific consent field. For older or unwritten agreements, you need a separate signed document recording consent.

If there is no written consent, email service is not valid and the notice has not been served. Many landlords assume email is automatically permitted because the tenant communicates by email. That is not enough — the consent must be in the lease agreement or a formal written addendum.

Proof: Keep the sent email with delivery confirmation. If your email client shows read receipts, save those. Screenshot the email with its full header if possible.

Methods That Will Get Your Notice Rejected

Letterbox delivery. Walking up to the property and dropping the notice in the tenant's letterbox does not qualify as lawful service — it is neither personal delivery (you did not hand it to anyone) nor ordinary post (it did not go through Australia Post). This is the single most common service mistake for self-managing landlords.

Registered or certified mail. If the tenant refuses to sign or does not collect it, the letter sits at the post office and is eventually returned. Service has not occurred, and you have wasted the entire notice period.

Text message or WhatsApp. No provision in the RTA recognises service by SMS, messaging app, or social media, even if the tenant reads it.

Taping it to the door. Not lawful service.

What the Court Checks

When a possession application reaches the Magistrates Court, the magistrate will verify that service was properly effected before looking at anything else. If you cannot prove lawful service, the application is dismissed regardless of how strong your case otherwise is.

The Ending a Tenancy in Western Australia guide includes a service proof log template — a single page where you record the method, date, recipient, and evidence for every notice you serve, so the proof is ready before you need it.
