Why NBN prices go up after the promo period
A great sign-up price can turn into a much higher bill a few months later. Here's how it works and what to check.
How promo pricing works
Many providers advertise a low introductory price for the first few months, then move you to a higher ongoing price. The number in big print is often the promo price, not what you'll pay for most of your contract.
Why prices also rise each year
nbn Co adjusts its wholesale prices each 1 July, generally in line with inflation. From 1 July 2026 the increase averaged just under 3.63%. Some providers pass these changes on to customers.
What to check before you sign up
- The ongoing price after any introductory period.
- Contract length and any early exit fees.
- Set-up and modem fees.
- Whether the price can rise during your contract.
- The speed tier you actually need (see our speed guide).
How to avoid a surprise
- Put the end of your promo period in your calendar.
- Compare ongoing prices, not just promo prices.
- Call your provider before the promo ends and ask what they can offer.
Our aim at Good On Us is fair, clear pricing with no big jump when a promo ends. Prices are confirmed before you decide, and this is general information, not personal advice.
