Telstra has announced another increase to mobile plan pricing, marking the second price rise in less than 12 months for millions of Australians.
From 5 May 2026, most Telstra post‑paid mobile plans will rise by $4 per month, while pre‑paid plans will go up by around $5 per recharge, a move the company says is necessary to fund ongoing network investment.
But while the focus has largely been on Telstra’s main‑brand customers, the increases will also hit users of Boost Mobile, Telstra’s wholly‑owned pre‑paid subsidiary — meaning customers who deliberately chose Boost to avoid Telstra‑level pricing are now facing higher costs as well.
Under the revised pricing structure announced in late March, Telstra confirmed that:
Telstra says affected customers are being notified directly ahead of the May implementation date.
Boost Mobile operates on Telstra’s full retail mobile network, a key selling point that distinguishes it from other Telstra‑backed budget brands. Unlike most MVNOs, Boost customers receive the same coverage footprint as Telstra’s own retail customers — including regional and remote areas.
However, Boost is also fully owned by Telstra, and its pricing decisions ultimately reflect Telstra’s broader cost structure. Following Telstra’s announcement, Boost confirmed it will also lift prices across its pre‑paid plans, with increases broadly aligned to Telstra’s own $5 per recharge rise.
That means customers who moved to Boost to escape repeated Telstra price hikes are no longer insulated from them.
While Boost has historically offered stronger value than Telstra’s main brand, the latest increases narrow that gap. Some Boost pre‑paid plans will rise by more than 10 per cent year‑on‑year when combined with previous adjustments, particularly on long‑expiry and higher‑data options.
Telstra and Boost argue the price rises are partially offset by higher data allowances on some plans. However, consumer advocates note that many Australians already carry unused data each month, meaning more data does not necessarily equal better value.
Boost Mobile isn’t the only Telstra‑owned brand affected by the latest price rise. Belong, Telstra’s budget post‑paid subsidiary, is also increasing mobile plan prices as part of the same broader reset — reinforcing the reality that there is no longer a true firewall between Telstra’s premium brand and its cheaper offshoots.
Belong was originally positioned as Telstra’s low‑frills, no‑contract alternative for price‑sensitive customers. But following Telstra’s latest announcement, Belong plans will rise by around $4 per month, with popular entry‑level options experiencing some of the largest percentage jumps.
For example, Belong’s 25GB SIM‑only plan — long marketed as a safe haven from Telstra’s annual price rises — is moving from the low $30s to the mid‑$30s per month, a double‑digit percentage increase for customers who chose Belong specifically to manage costs.
For Belong customers, the impact is arguably sharper than for Telstra’s premium users.
A $4 increase on a $80 Telstra Essential plan is irritating.
A $4 increase on a $30–$34 Belong plan is structural.
It pushes budget users closer to price points where competitors on Optus or Vodafone networks become more attractive — particularly for metro customers who don’t need Telstra’s regional reach.
And unlike Telstra’s main brand, Belong customers don’t receive:
Which raises a difficult question: at what point does Belong stop being worth it?
| Provider | Monthly Price | Data Allowance | Network | Notes |
|---|---|---|---|---|
| Telstra | $74 | 50GB | Telstra | Cheapest main Telstra post‑paid plan after May 5 increase; Premium plan remains $99 |
| Optus | $59 | 60GB | Optus | Cheaper than Telstra with more data; reduced regional coverage compared to Telstra |
| Vodafone | $49 | 50GB | Vodafone | Lowest major‑brand price; strongest in metro areas, weakest regional reach |
| Boost Mobile | $39 | 30GB | Full Telstra | Uses Telstra’s entire retail network; prepaid only, fewer extras |
| Belong | $34 | 25GB | Telstra (wholesale) | Telstra‑owned; slower speeds, smaller data pools, no 5G priority |
Telstra says the latest increases are required to fund continued investment in coverage, capacity, security, scam protection, and 5G reliability, as well as emerging services such as satellite‑to‑mobile messaging.
According to Telstra, customers are using more mobile data than ever, and ongoing investment is needed to maintain what it describes as Australia’s most resilient mobile network.
From a corporate perspective, mobile services remain Telstra’s single biggest revenue stream, generating more than $3 billion annually and accounting for over a quarter of total earnings.
Telstra holds roughly 41 per cent of Australia’s retail mobile market, giving it enormous influence over pricing across the sector. When Telstra lifts prices, its subsidiaries and dependent MVNOs often follow — not because they want to, but because their wholesale and operational costs rise at the same time.
The result is a price floor effect, where nominally “budget” options gradually become more expensive, reducing real competition for customers who need strong coverage rather than just cheap data.
For Boost customers in particular, the latest increase is a reminder to reassess priorities:
In an environment where prices are rising across the board, re‑evaluating loyalty may be the only effective response.
Telstra’s latest mobile price rise isn’t just a Telstra issue. By flowing through to Boost Mobile, it highlights how deeply pricing decisions at Australia’s largest telco affect the broader market.
For customers who chose Boost to avoid Telstra‑level costs, the message is clear: there are fewer hiding places from mobile price inflation — even on prepaid.
As cost‑of‑living pressures continue, patience with repeated price hikes may be wearing thin. The question now is whether Telstra’s network advantage is still enough to justify the premium — or whether more Australians will finally decide to walk.
