ACCC says Australians are paying for more mobile data than they need

By Alex Choros

Last updated 18 December 2024

Many Australians are sitting on a trove of unused mobile data, according to the ACCC's newly released Internet Activity Report and Communications Market Report.

The regulator found that the average data allowance for mobile plans advertised in the 23/24 Financial Year was 68GB per month. Despite this, the average data usage was only 14.2GB per month, per user.

This figure combines both postpaid and prepaid services. Broken out, postpaid customers used 17.4GB per month, while prepaid customers used 9.3GB per month. That's an increase from 15.9GB and 7.5GB in last year's Internet Activity Report.

"Despite increased usage in recent years, consumers do not use the higher allowances that have been offered over time and may instead prefer lower data allowances for a lower price," wrote the ACCC.

One of the issues is that Telstra, Optus, and Vodafone simply do not offer plans with lower allowances. On postpaid, 50GB is the starting allowance for the Big Three telcos.

"The price increases in mobile plans observed in recent years are often accompanied with significant increases in data allowances," wrote the ACCC. "This suggests that while the plans may have become more expensive, they are offering more value by way of more included data. However, consumers may not value having a greater data allowance."

Smaller providers - including sub-brands owned by the Big Three - do have plans with more reasonable data allowances at a cheaper rate, however.

These are the cheapest prepaid mobile plans in the WhistleOut database with at least 10GB:
