Australia is an awkward place to build a mobile network. Customers cluster in cities, then expect their phones to work when they leave them. The road trip exposes the weakness in the bargain: a competitively priced plan loses much of its charm when the signal disappears. TPG Telecom’s response has been to redraw the bargain with its rivals.
The group behind Vodafone, TPG, iiNet, Lebara and felix is pursuing more reach with less infrastructure on its own books. In January 2025 it switched on regional network sharing with Optus. Later that year it sold its fibre assets and enterprise, government and wholesale fixed business to Vocus for an enterprise value of A$5.25 billion. The company that emerged still sells connections. It has changed how much of the machinery it needs to own.
That makes TPG an interesting challenger to Telstra and Optus. Its competitive pitch depends on familiar retail brands, a mobile network with greater reach and a willingness to purchase infrastructure access from companies it also competes against. The arithmetic is promising. The customer still gets to mark the homework.
01 / THE DEALA rival becomes the regional landlord
The Optus arrangement tackles a specific weakness. At announcement, TPG described a regional footprint of about 755 sites. The agreement gave it access to 2,444 Optus sites, extending national geographic coverage from roughly 400,000 square kilometres to around one million. The launch arrived in January 2025. By its August 2026 investor presentation, TPG reported mobile population coverage of 99%.
The distinction between people and land matters. A population percentage follows where Australians live; it does not promise reception across that share of the continent. Nor does a national figure describe the signal inside a particular house. Vodafone Business now advertises around 1.2 million square kilometres of coverage. Customers need the map for their actual routes, not just the headline percentage.
Geographic footprint, not population coverage. Approximate announcement figures; the footprint has since expanded further.
Under the deal, Optus uses some of TPG’s spectrum in the regional sharing area and supplies radio network services in return. Each carrier keeps its own core network, and they continue operating their own metropolitan mobile networks. This is shared plumbing with separate shopfronts. A Vodafone subscriber does not become an Optus retail customer.
The arrangement runs initially for 11 years, with a five-year extension option. It lets TPG compete for regional residents and for city customers who travel beyond the suburbs. That second audience is easy to underestimate: an infrequent trip can influence a phone-plan decision made every month.

02 / THE BILLMore coverage comes with an invoice
TPG’s original estimate put service fees payable to Optus at A$1.59 billion over the initial term. Expected receipts for access to TPG’s spectrum totalled about A$420 million, leaving estimated net payments of A$1.17 billion. TPG estimated that net figure at roughly one-third of the cost of building, operating and maintaining a comparable regional network itself.
Those are long-term estimates, not a claim that the entire saving has already arrived. Sharing also made some existing assets redundant. TPG’s 2024 results included a A$250 million non-cash impairment of regional mobile sites associated with the transition. The bigger network came with both a supplier commitment and an accounting reckoning for the smaller one.
The first attempt used a different partner. TPG and Telstra sought authorisation for regional sharing in 2022. The competition regulator refused, concerned about the longer-term effect on competition. The Australian Competition Tribunal upheld that outcome in June 2023. In September 2024 the regulator announced it would not oppose the Optus arrangement.
This was the practical change in direction: the goal of sharing survived, while the counterparty changed. There is no need to invent a boardroom epiphany. The public record shows a blocked route, an unsuccessful appeal and a subsequent deal with another operator. A partnership can be financially attractive and still fail the competition test.
03 / THE EXITThe fibre left. The customers did not all follow.
The Vocus transaction changed another boundary. TPG’s annual report records completion on July 31, 2025. Vocus acquired the fibre network infrastructure and enterprise, government and wholesale fixed operations, including the Vision Network wholesale residential business. TPG kept its mobile operations and consumer broadband business, supported by new commercial arrangements for fixed-network access.
The A$5.25 billion enterprise value is not interchangeable with cash available to spend. TPG reported approximately A$4.7 billion in net cash proceeds. That funded a A$3 billion shareholder distribution and A$1.7 billion in debt reduction. A shareholder reinvestment plan and a handset-receivables financing programme helped take total bank-borrowing repayments during 2025 to approximately A$2.7 billion.
For buyers, the dividing line is useful. TPG’s current corporate site directs mobile, IoT and mobile private-network enquiries to Vodafone Business. The fixed enterprise portfolio moved to Vocus. An old description promising TPG-owned fibre, dark fibre and a full enterprise fixed stack now needs a date attached.
The business model remains familiar: recurring service charges, supplemented by handset and hardware revenue. The ownership model is more selective. TPG still needs fibre to carry traffic and wholesale broadband to serve homes. Selling the assets shifts the economics toward access agreements; it does not make the underlying network unnecessary.
04 / THE SHOPFRONTSOne group, several reasons to sign up
TPG’s name carries two histories. The current merged group took shape in July 2020 when Vodafone Hutchison Australia combined with TPG Corporation. The original TPG business, associated with founders David and Vicky Teoh, began in computers. Its corporate timeline starts in 1986, under the wonderfully literal name Total Peripherals Group.
Today’s customers encounter a collection of brands. Vodafone sells mobile plans, devices, roaming and broadband. TPG and iiNet carry longstanding internet-provider identities. Lebara addresses value-conscious mobile customers, including those making international calls. felix offers a digital subscription proposition with environmental commitments. Internode also remains part of the group’s published brand history and portfolio.
Across those shopfronts, the problems are ordinary and persistent: getting the household online, keeping a travelling employee reachable, managing a phone bill and connecting business devices. Vodafone Business publishes customer testimonials from Brewtech, Killara Distillery and accessories business Dylan Kain. These examples make the audience more tangible than a catalogue of enterprise acronyms.
For a prospective customer, the sensible comparison starts with the service needed. Check mobile coverage at home, work and regular destinations. For broadband, check address eligibility, speed information and the price after any introductory discount. Fixed wireless can provide home internet over the mobile network, but eligibility and performance depend on location and network conditions. A bargain for one household may be a poor fit next door.
05 / THE SCOREMobile climbs. Broadband pushes back.
The August 2026 results give the strategy a mixed but readable scorecard. TPG added 64,000 mobile subscriptions in the first half, reaching 5.806 million. Mobile service revenue rose 3.1%. Home broadband service revenue fell 1.9%, with the company describing intense NBN competition. Its fixed subscriber base stood at 1.941 million. Those counts are subscriptions, not distinct Australians.
Different directions inside the same company.
Group service revenue increased just 0.5% to A$2.071 billion. Continuing-operations net profit was A$35 million, compared with A$32 million a year earlier. TPG also publishes pro forma comparisons that assume the post-Vocus commercial arrangements existed in the earlier period. Those help assess the retained business, but they should not be confused with the statutory comparison.
The expertise behind the numbers includes running radio networks, managing spectrum, buying wholesale inputs and serving different customer segments through multiple brands. None guarantees that a subscriber will stay. A larger coverage footprint has to survive the less glamorous tests of billing, support and reliable everyday use.
06 / THE OBLIGATIONA working phone is the point
The stakes extend beyond a dropped work call. In November 2025, TPG disclosed that a Sydney customer using a Lebara service on a Samsung device could not make Triple Zero calls, and that a person died. TPG said its network was operational and its early investigation pointed to incompatible device software. That was the company’s preliminary account. The incident underlines how network reach and device compatibility must work together.
Inside the organisation, TPG promotes values including Simple’s better
, alongside inclusion and employee development. Its careers material describes a learning hub and internal training. These are stated commitments; the test customers experience is whether the company makes a complicated service easier to use and maintain.
There is a concrete environmental milestone, too. In May 2026, TPG announced that it had matched all operational electricity use with renewable electricity since December 2025. The mechanism combines power purchase agreements with renewable energy certificates. It is a precise procurement claim, rather than a promise that each tower runs directly on its own solar panels.
07 / THE NEXT SIGNALA small message from space
TPG’s coverage ambitions also reach beyond terrestrial sharing. In May 2025 it announced successful satellite text-message tests with Lynk Global from rural New South Wales, using ordinary smartphones. One message read Happy Easter!
, a wink at Vodafone’s famous 1992 Christmas greeting. The trial demonstrated a possible extension of mobile coverage; it should be read as a trial, not a retail-service promise.
The copyable lesson is more earthbound. Identify the customer constraint, price the build-versus-access alternatives and choose a partner whose incentives and regulatory position make the arrangement workable. Then measure retention and revenue, not just the enlarged footprint. The approach depends on suitable shared infrastructure, acceptable terms and enough customers to support ongoing fees. TPG has bought itself a broader opportunity. Every monthly renewal will help decide what it is worth.
