TPG Telecom is continuing to attract mobile customers at the expense of pricier rivals, with its affordable and easy-to-cancel plans proving popular with a growing number of Australians.

In the six months to June 30, the telco added 140,000 mobile users, lifting the total to 5.62 million.

Much of that growth came from its no-frills Felix, TPG and iiNet brands, where customers can sign up for rolling deals without being locked into contracts.

CEO Iñaki Berroeta calls those commitment-shy customers the “Netflix subscribers of the telco world”. Such customers now appear to make up the fastest-growing segment of the market.

TPG’s latest results suggest Berroeta is on to something. In the six months to June 30, the company’s net profit more than tripled to $32 million, while revenue nudged up to just over $2 billion.

TPG’s fortunes have also been bolstered by its A$1.6 billion network-sharing deal with Optus, which doubled its regional footprint and added 100,000 regional customers in early 2025.

Telstra and Optus have been slow to respond to changing consumer preferences

In contrast, Telstra lost ground over the same reporting period. While it chose to highlight the increased sales of postpaid mobile plans, Telstra has experienced a net decline in customers since the TPG-Optus tie-up.

Optus also appears to have been impacted.

It recently warned its parent, Singtel, of “headwinds” from budget brands such as TPG, Felix, and Aldi Mobile.

Berroeta argues the shift is structural, with Australians moving away from expensive postpaid contracts in favour of cheaper, simpler plans.

For now, TPG’s stripped-down, subscription-style model certainly seems to be landing punches on both Telstra and Optus.
