Month-to-Month vs 12-Month nbn Contracts Explained

When you sign up for an nbn plan, you'll typically choose between a month-to-month arrangement and a 12-month fixed-term contract. Each has trade-offs that depend on your circumstances.

Month-to-month nbn plans

Month-to-month (no-contract) plans give you maximum flexibility. You can cancel with 30 days notice and switch providers without any penalty. This is valuable if you rent, expect to move, or aren't sure which provider you'll prefer.

The trade-off is usually a slightly higher monthly price — typically $5–$15 more than the equivalent fixed-term plan. Some providers also don't include a modem on no-contract plans (you must buy or already own one).

12-month fixed-term contracts

Fixed-term contracts typically offer lower monthly rates, and often include a free or discounted modem. If you sign a 12-month contract and cancel early, you'll owe an early termination fee that can be significant.

Important: If you're renting and there's any chance you'll need to move within 12 months, be very cautious about fixed-term contracts. Some providers waive exit fees if you move to an address outside their service area, but this isn't universal.

Which is better for you?

Homeowner, staying put	12-month (if price is right)
First time with a new provider	Month-to-month (test first)
Happy with current provider, want savings	12-month
Uncertain about your needs	Month-to-month

What to watch out for in nbn contracts

Early termination fees

Read the ETF structure carefully. The worst-case scenario is paying the remaining months of your contract in full. Some providers have more reasonable flat-fee ETFs.

Price changes mid-contract

Most providers reserve the right to change prices even within a contract period, with adequate notice. Check whether price increases allow you to exit penalty-free.

Automatic rollover

When your 12-month contract ends, you usually roll onto month-to-month at a different rate. Set a calendar reminder at month 10 to shop around before renewal.

Modem rental vs purchase

Some contracts include a "free" modem that's actually a rental — it must be returned when you leave. Make sure you understand whether the modem is yours to keep.

Frequently asked questions

Can I cancel my nbn plan at any time?

On month-to-month plans, yes — usually with 30 days notice and no penalty. On fixed-term contracts, early termination fees apply and can be substantial (sometimes the remaining months' plan cost). Always read the critical information summary before signing.

Do 12-month nbn contracts save money?

Often, yes — but not always. Some providers offer $10–$20/month discounts for 12-month commitments plus a free modem. But if the provider's prices are higher than a no-contract competitor, the discount may not offset the difference. Always compare the total 12-month cost.

What happens at the end of a 12-month contract?

Most providers roll you onto a month-to-month arrangement at the same or higher rate. It's worth reviewing your plan at contract end — you may be able to renegotiate a better deal or switch providers without penalty.

Is there a cooling-off period for nbn contracts?

Yes. Under Australian Consumer Law, you have a 10-business-day cooling-off period for most contracts signed outside a business premises (e.g. online or over the phone). Check your provider's terms — many extend this to 30 days.

What is an early termination fee?

An early termination fee (ETF) is charged when you cancel a fixed-term contract before it ends. ETFs vary widely — some are a flat fee ($200–$500), others are the remaining months' cost. Always check the ETF before signing up, especially if you might move within the contract period.
