Can a supplier contract automatically renew in Australia?

Auto-renewal is the clause that costs Australian buyers the most, because missing it never feels like a decision. It is lawful, but in a standard form contract with a small business an unreasonable renewal term can fall foul of the unfair contract terms regime.

Last checked 2026-08-02. Australian law changes, and this page states the position as at that date.

How the clause actually works

Most business contracts continue past their initial term unless someone stops them. The renewal clause sets two things: how long the next term runs, and how far in advance you have to give notice if you do not want it.

The second number is the one that matters. A 90 day notice window on a 12 month contract means your real decision date is nine months in, not twelve. By the time the renewal date is visible in your calendar, the window has usually closed.

Where the unfair contract terms regime comes in

Automatic renewal is legal. What can make a particular clause unlawful is the combination of a standard form contract, a small business counterparty, and a renewal mechanism that is significantly one-sided.

The Australian Consumer Law lists a term that permits automatic renewal without adequate notice among the kinds of term that may be unfair. It is an example, not an automatic finding: the three-limb test still has to be met, meaning significant imbalance, not reasonably necessary to protect a legitimate interest, and detriment.

In practice, the features that draw attention are a long notice window, no reminder before it closes, a renewal term longer than the original, and a price that can rise on renewal without giving you a right to leave.

What to check before you sign

The length of the notice window
Across the SaaS contracts we measured, the median notice window was 30 days. Longer windows are common in master services agreements, where 90 days was the median.
How notice has to be given
A clause requiring written notice by post to a registered office is a real obstacle. Ask for email to a named address to be sufficient.
The length of the renewal term
A 12 month contract that renews into another 12 months is normal. One that renews into a longer term, or into a term you cannot exit at all, is worth pushing back on.
What happens to price on renewal
If the supplier can increase the price on renewal, you want either a cap on the increase or a right to terminate once you are told the new price.
Whether you get a reminder
Ask for a contractual obligation on the supplier to notify you before the window opens. Suppliers who are confident in their product usually agree.

Common questions

Are automatic renewal clauses legal in Australia?
Yes. Automatic renewal is lawful. What can be unlawful is an automatic renewal term in a standard form contract with a consumer or small business where the term is significantly one-sided, is not reasonably necessary to protect the supplier's legitimate interests, and would cause detriment. The Australian Consumer Law lists renewal without adequate notice as an example of a term that may be unfair.
What is a normal auto-renewal notice period?
It depends on the contract type. Across the SaaS agreements we measured the median notice window was 30 days, while master services agreements sat at 90 days. Anything materially longer than that for the same kind of contract is worth questioning.
What if I miss the notice window?
You are generally committed to the next term. It is still worth asking the supplier, particularly if you missed it narrowly or were never reminded, because many will negotiate rather than hold an unhappy customer to a full term.
