Australia 5G Core Network Market Size, Share, Growth and Forecast, 2025-2035

Three carriers and new private networks set core spending

The Australia 5G core network market was valued at USD 109.5 million in 2025 and is projected to increase from USD 138.0 million in 2026 to USD 698.6 million by 2035, registering a CAGR of 19.75% during 2026–2035. Spending comes from Telstra, Optus and TPG Telecom as they move traffic onto standalone platforms, and from mines, rail lines and event venues that now run dedicated networks. New South Wales held the largest regional share, 33.0% in 2025, because it holds the largest population and major rail and mining projects. Western Australia is the fastest-growing region at 20.91% a year, as it posted the quickest population growth in the year to March 2026. Compliance now forms part of core network budgets as well, because Australia’s Triple Zero Custodian law commenced on Oct. 31, 2025, after the Optus outage of Sept. 18, 2025, and it raised penalties for emergency-call failures. As a result, buyers now weigh testing and monitoring alongside capacity when they renew core contracts.

Which carrier and enterprise purchases make up Australian core spending?

The market counts spending on core software, integration, managed operation and dedicated enterprise cores that serve 5G traffic in Australia. Buyers are the three national mobile carriers, along with mining, rail, port and public safety operators that run private networks. Most carrier purchases are multi-year vendor agreements, and they combine software licenses with support and upgrades.

The estimate excludes radio equipment, towers, transmission and spectrum fees, even though those items compete for the same capital budgets. It also excludes the mobile service revenue that carriers earn from subscribers. Value moves from vendors and integrators to carriers and enterprises, and managed services are counted where a third party operates the core.

Carrier software leads while private cores gain the most

Why carrier software leads and private cores grow fastest

Based on solution type, the market is categorized into public-network core software, professional services, managed core services and private-network core solutions. Public-network core software led with 46.0% of 2025 value because national carriers buy at scale, and TelecomLead reported in August 2026 that Telstra alone ran 26.027 million retail mobile services. Private-network core solutions grow fastest at 21.90% a year as dedicated sites multiply, and IT Brief reported in November 2024 that BAI Communications secured up to 50 MHz of 3.8 GHz spectrum. Migration projects also draw on cloud professional services skills held by integrators.

How cloud-native platforms displaced older packet cores

Based on technology, the market is categorized into cloud-native standalone core, virtualised standalone core and 5G-enabling evolved packet core. Cloud-native standalone core led with 56.0% of 2025 value because TPG Telecom consolidated 4G, non-standalone and standalone data onto one Ericsson dual-mode core, according to TelecomTalk in December 2023. The same segment grows fastest at 21.04% a year as Telstra, which reported a cloud-native core in May 2020 according to RCR Wireless, adds 5G Advanced functions. Older function virtualization stacks keep some share while carriers finish their migrations.

Why mobile broadband pays for most core capacity

Based on application, the market is categorized into enhanced mobile broadband, enterprise service differentiation and industrial operational connectivity. Enhanced mobile broadband led with 62.0% of 2025 value because consumer traffic still sizes the core, and Telstra said in February 2025 that mobile data demand on its network had tripled over the past five years, according to Ericsson. Industrial operational connectivity grows fastest at 21.94% a year as machine control outgrows Wi-Fi, and RCR Wireless reported in August 2024 that private 5G at the Cadia mine reached 150 Mbps upload against 20–30 Mbps on Wi-Fi.

How direct contracts and integrators divide core sales

Based on sales channel, the market is categorized into direct vendor contracts, operator-led solutions and integrator-led solutions. Direct vendor contracts led with 50.0% of 2025 value because carriers negotiate core supply themselves, as TPG Telecom did when it chose Ericsson in September 2021, according to Technology Decisions. Integrator-led solutions grow fastest at 21.32% a year as enterprises seek a single accountable partner. In February 2026, ChannelLife reported that Metro Trains West named BAI Communications as delivery partner for a private 5G train system on Sydney Metro West.

Standalone, programmability and voice rules drive budgets

Standalone platform migration moves traffic to new cores

Standalone migration lifts spending because each carrier must move subscribers, policy and data sessions from older packet platforms to a service-based core. Telstra set the pace in May 2020, when RCR Wireless reported that Ericsson had added a cloud-native core able to carry standalone traffic, while 5G covered parts of 32 cities and towns. TPG Telecom followed, and TelecomTalk reported in December 2023 that a single consolidated core then handled all of its data traffic. Optus has since shown what the platform can carry, recording 3.4 Gbps downlink and 200 Mbps uplink at its Sydney campus on a live standalone network, according to the IEEE Communications Society Technology Blog in May 2026. As a result, cloud-native platforms held 56.0% of 2025 value.

Programmable network evolution opens paid service tiers

Programmability gives carriers a reason to fund the core beyond capacity, because tailored connectivity requires policy control and exposed network functions. Telstra committed to this model in a four-year deal that Ericsson and Telstra announced on Feb. 19, 2025, which covers 5G Advanced software and Open RAN-ready hardware and aims to double 5G capacity. In the same release, Telstra said demand for mobile data on its network had tripled in five years, and it described a move away from one-size-fits-all plans. TelecomLead reported in August 2026 that about 1,200 Telstra sites had reached 5G Advanced capability in fiscal 2026. Core platforms that support slicing therefore turn radio upgrades into sellable tiers. In turn, enterprise customers gain a reason to pay for assured performance.

Voice-core modernization follows the closure of 3G

Voice-core work has become unavoidable because calls now depend entirely on packet voice systems rather than circuit fallback. TPG Telecom closed 3G in January 2024, and Telstra and Optus followed in November 2024, according to the Department of Infrastructure, which warned that phones without VoLTE cannot call over 4G. This change put emergency calling on the same platforms that carry data, and the Triple Zero Custodian law commenced on Oct. 31, 2025, to oversee it. Telecoms.com reported that the maximum penalty for breaching Triple Zero rules rose to A$30 million, while carriers must test emergency calling during upgrades and maintenance. Consequently, voice functions now attract testing, redundancy and monitoring budgets. These requirements reach every national carrier and support recurring demand for managed support.

High mobile penetration and data growth size the core

A dense subscriber base keeps core capacity growing even though Australia adds relatively few new users. World Bank data show 112.58 mobile subscriptions per 100 people in Australia in 2024, which points to more active lines than residents. Machine traffic adds to this load, and TelecomLead reported that Telstra’s IoT connections rose 12.5% to 11.074 million in fiscal 2026. Carriers are funding the capacity, with Optus saying in May 2026 that it invested about A$1.5 billion in networks and IT systems in fiscal 2026. Therefore, Enhanced mobile broadband kept 62.0% of 2025 value in this report. That spending pattern suggests capacity, rather than new coverage, still sets the size of most core contracts at the largest carriers.

Resilience work and private networks reshape core demand

Shift toward 5G Advanced functions on standalone cores

Carriers are shifting from coverage milestones toward features that only work well on standalone platforms. Optus and Ericsson demonstrated aggregation of 180 MHz across 2.3 GHz and 3.5 GHz on commercial devices, including the Samsung Galaxy S26 Ultra, according to the IEEE Communications Society Technology Blog in May 2026. The same source reported Telstra deploying Ericsson carrier aggregation optimization across more than 50 live 5G Advanced sites. Telstra’s four-year Ericsson deal of February 2025 also covers 5G Advanced software, according to Ericsson. As a result, core upgrades increasingly arrive as feature releases rather than one-time replacements, so carriers now budget for recurring software work across each network.

Rise of resilience as a core operating requirement

Resilience has risen from an engineering concern to a board-level purchase criterion since the Optus outage of Sept. 18, 2025. ChannelNews reported that Optus is speeding up the transfer of network monitoring from Nokia, which it had planned to complete by May 2027, and adding 150 staff to a process center of excellence. Optus said in May 2026 that it has expanded automated Triple Zero testing and set up a dedicated 24/7 monitoring team. The Department of Infrastructure reported that the regulator was directed to require public outage registers by June 30, 2026. These steps raise demand for observability and change-control tools around the core. In turn, testing and monitoring now compete with new features for core budgets at each carrier.

Opportunity in private cores for mines and industrial sites

Mining offers a clear opening because automated equipment needs reliable uplink that Wi-Fi struggles to provide underground. RCR Wireless reported in August 2024 that a trial at the Cadia mine in New South Wales, begun in February 2023, reached about 90 Mbps upload on access drives, and false safety stops had been a problem under Wi-Fi. Newmont then extended its Ericsson private 5G work to underground and surface operations. Fierce Network separately reported that the Australian Grand Prix Corporation ran private 5G at Albert Park for ticketing and point-of-sale systems in March 2025. These cases show that private network demand now reaches beyond mining sites. Vendors that can package a small core with spectrum access can therefore address Industrial operational connectivity growth of 21.94% a year.

Opportunity in mission-critical rail and public safety cores

Rail and emergency agencies present a second opening, because their contracts run for many years and demand high availability. ChannelLife reported in February 2026 that BAI Communications will deliver a private 5G train communication system for the 24 km Sydney Metro West line, which is scheduled to open in 2032 with 16 driverless trains. That contract is described as Australia’s first for a 5GMCX-based rail radio system, offering a pathway to the FRMCS standard. BAI also manages the NSW Public Safety Network, which connects more than 50 agencies and 75,000 terminals, according to RCR Wireless in July 2026. As a result, mission-critical work can support long-term demand for Integrator-led solutions, the group growing at 21.32% a year.

Spectrum fees and outage liability test core investment

Spectrum renewal costs compete with core budgets

Spectrum renewal is the largest competing call on capital because guidance from the Australian Communications and Media Authority in December 2025 put renewals at A$7.3 billion, up to A$2.3 billion more than carriers expected. Most licenses renew between 2028 and 2032, so the cost falls within this forecast period. Telstra warned of downward pressure on network spending, while Optus cited a threat to funding for upgrades. Vendors may therefore face longer sales cycles and phased orders. Carriers can respond by favoring software releases that reuse existing cores.

Outage liability raises the cost of every core change

Upgrades now carry greater legal and reputational risk, and the Optus outage of Sept. 18, 2025, shows why. RNZ reported that about 75% of calls from 605 Triple Zero callers failed over almost 14 hours, and the independent review found at least 10 mistakes during a routine upgrade. Carriers and their contractors must now absorb extra testing and approvals, which slows release schedules. Automated pre-change testing can reduce that burden, although it adds cost to each migration.

Rising traffic and tight capital limit core upgrade payback

Payback remains uncertain because traffic keeps rising while capital budgets stay tight. Telstra said in February 2025 that mobile data demand on its network had tripled over five years, according to Ericsson. TelecomLead reported that Telstra’s capital spending slipped 0.7% to A$3.365 billion in fiscal 2026. Finance teams therefore question new platforms unless paid tiers are visible. Vendors can respond with phased licensing tied to service launches.

Supplier concentration exposes carriers to shared faults

Reliance on a small supplier group concentrates operational risk, since Telstra and TPG Telecom both selected Ericsson for their cloud-native cores. Fault detection is one concern, and Capacity reported that a Dapto tower outage on Sept. 28, 2025, lasted about nine hours after Ericsson equipment failed to raise an alarm, according to Optus. Although that fault was limited to one site, it shows how vendor tooling shapes recovery times. Multi-vendor designs can reduce the exposure, but they add integration cost for carriers.

Population and major projects put New South Wales ahead

New South Wales leads on population and major projects

New South Wales held 33.0% of 2025 value and grows at 19.31% a year. The Australian Bureau of Statistics counted 8.67 million residents on March 31, 2026, the largest state total, which gives it the deepest subscriber base. Project demand adds to that base, since the Cadia mine and the 24 km Sydney Metro West line both sit in the state. In addition, Optus used its Sydney campus for its May 2026 standalone demonstration, which reflects the concentration of engineering work there.

Victoria follows on subscriber scale and event networks

Victoria held 26.0% of 2025 value and grows at 19.41% a year. The Australian Bureau of Statistics counted 7.15 million residents on March 31, 2026, after an annual gain of 109,500, the largest increase of any state. That gain lifts core demand in Melbourne and its suburbs, adding traffic that carrier platforms must carry. Enterprise use is also visible there, because the Australian Grand Prix Corporation ran private 5G at Albert Park during the March 2025 race.

Queensland adds regional spectrum and steady user growth

Queensland held 19.0% of 2025 value and grows at 20.11% a year. The Australian Bureau of Statistics counted 5.74 million residents on March 31, 2026, up 1.6% in a year. Spectrum access is a local feature too, because X4000 Communications won 75% of Queensland’s area-wide millimeter-wave licenses in May 2022, according to TechPartner. These holdings give private network buyers in the state another supply option beyond the national carriers.

Western Australia grows fastest on population and resources

Western Australia held 13.0% of 2025 value and grows at 20.91% a year, the fastest pace among the zones. The Australian Bureau of Statistics counted 3.10 million residents on March 31, 2026, and its 2.1% annual growth rate was the fastest of any state or territory. That pace supports core demand as carriers add capacity for new residents. Credence Research also assumes that resource operators will favor private cores here, following the underground results reported at Cadia in New South Wales.

Rest of Australia remains a smaller and more dispersed base

Rest of Australia held 9.0% of 2025 value and grows at 19.81% a year. This zone combines South Australia, Tasmania, the Northern Territory and the Australian Capital Territory, which together held about 3.26 million residents on March 31, 2026, according to the Australian Bureau of Statistics. Low density limits core demand across those four jurisdictions, so these areas mostly rely on platforms hosted elsewhere. Dedicated sites are likely to supply much of the incremental spending.

Dated deals and rulings that moved Australian core plans

Cloud-native functions change how carriers run the core

• Dual-mode cores let carriers such as TPG Telecom run 4G, non-standalone and standalone data on one platform, which removes parallel upgrade work.
• Network exposure functions give developers controlled access to carrier capabilities, and the Aduna venture counts Telstra and Ericsson among its founding members.
• Edge-hosted user planes place traffic handling closer to users, which is why core planners track edge computing sites alongside central facilities.
• Automated pre-change testing checks emergency call paths before and after upgrades, a practice Optus said in May 2026 it had expanded.

Ericsson anchors carriers as specialists chase enterprises

Ericsson holds the strongest position among carriers, since Telstra and TPG Telecom both selected it for cloud-native cores, and Optus used Ericsson for its May 2026 standalone demonstration. Nokia competes through carrier services and partnerships, including a February 2022 memorandum with TPG Telecom on private networks for mining and energy, although Optus is now moving network monitoring away from it. Telstra acts as both buyer and seller, because Telstra Purple supplied equipment and spectrum for the Cadia trial. BAI Communications competes through licensed spectrum and long-term rail and public safety work, while X4000 Communications sells spectrum with an end-to-end network offer. Vocus operates more than 50,000 km of owned fiber after its TPG Telecom deal, an asset base closer to dark fiber and enterprise connectivity than to core supply. Competition therefore depends on carrier references, spectrum access and the ability to take operational responsibility.

Carrier, vendor and spectrum roles in Australian core supply

Where Australian core spending moves after standalone

Credence Research’s view is that the Australian core network market is moving from a migration story to an operating story. The first standalone platforms are already live, so the next budgets will favor features, testing and accountable operation. Carrier software remains the largest pool, yet the outage findings of December 2025 show that a technically sound core can still fail through poor procedures. Vendors should therefore price services around change safety as well as capacity. Private networks offer faster growth from a small base, although results at sites such as Cadia must be repeated widely before they become routine purchases.

Population data and carrier records underpin the estimates

The report uses 2025 as the base year and forecasts values for 2026 through 2035 from the Credence Research market model. Segment and regional splits are Credence Research estimates rather than published statistics. Regional zones were built from Australian Bureau of Statistics population data and known project locations. Supporting evidence came from company releases, government and regulator documents, World Bank data, carrier results and telecom trade publications. No interviews or surveys were conducted for this edition, so assumptions about spending per subscriber and private network uptake are the most judgment-heavy inputs.

Enterprise cores and programmability shape growth to 2035

The core network market is forecast to reach USD 698.6 million by 2035, growing at a 19.75% rate through 2026–2035. Carrier migration should dominate early years, while 5G Advanced services and license renewals between 2028 and 2032 shape spending in the middle of the period. Enterprise cores should then add a larger share, particularly if mining and rail deployments repeat the performance reported at Cadia and delivery on Sydney Metro West proceeds toward its 2032 opening. Regulation will remain a steady influence, because Triple Zero obligations apply to each change that carriers make to their networks. Buyers are likely to reward vendors that can prove safe upgrades.
