The average phone bill per month: Phone on a plan
The average bill for customers on a bundled phone plan is much more expensive that for SIM-only plans, as you’re paying for both your mobile service and the price of your phone on the one bill. On average, customers with a phone on a plan pay $82 per month, or $984 per year. This is up from $78 per month in 2024, which was down from the average of $90 per month in 2023, $87 per month in 2022 and $81 per month in 2021.
Customers in Western Australia pay the most on average for their plan, while those in Tasmania pay the least. Here is a break down of the average bill for phone on a plan, from each state and territory:

These costs are hardly surprising, as the most premium smartphones can easily add $50 or more on to your bill each month. There are also only a small number of telcos offering phones on plans, so your choices are generally limited to Telstra, Optus or Vodafone. These three telcos tend to be pricier than smaller competitors, with postpaid plans beginning at around $50 per month.
Canstar Blue’s 2025 survey also found that phone on a plan users tended to have higher data inclusions. 22% of respondents had 50GB to 99.99GB of monthly data included in their plan, while 19% had 20GB to 49.99GB of data included, 17% had 100GB+ data, while 15% were unsure how much data they had. However, just 38% of survey respondents said they could comfortably afford the monthly costs of their phone plan, but this was up from 36% in our 2024 survey.

Am I paying too much for my phone bill?
If you’ve seen any of the above averages and worried that you’re paying too much for your phone bill, there’s a lot to consider when it comes to choosing a phone plan. If you’re currently happy with your plan’s price, inclusions and service, you might be happy to stick with the same plan, or look at similar plans from other providers to see if you can get a better deal.
Otherwise if you feel like you are paying too much for your phone bill and want to switch plans, you’ll need to compare plans from a range of telcos. Your first step is making sure you know what sort of inclusions you want, especially how much mobile data you need. Consider how much data you use on average with your current plan and go from there.
While we’ve already shared a range of phone plans in this guide, there are plenty of other plans and providers that you can compare with our free phone plan comparison tool. Remember that before you sign up, you should check the information and details of that plan so you’re aware of any fees, setup costs or surprise charges.
