Is Telstra profitable in 2026?

Yes. Telstra reported FY25 (year ended 30 June 2025) net profit of A$2.3 billion, up 31% year on year, with free cash flow up 92% to A$3.96 billion. FY26 EBITDA guidance issued August 2025 is A$8.15-8.45 billion, suggesting continued profitability.

Could AI replace Telstra?

No. Telstra's moat is physical: 99.7% population mobile coverage, national spectrum licenses, and regulated critical-infrastructure status that AI cannot replicate. AI is instead used internally, via 21,000 Microsoft Copilot licenses (as of October 2025), to cut costs and headcount, not to threaten the network itself.

Telstra Group Limited is fully publicly traded on the ASX under ticker TLS, with no controlling shareholder; it was fully privatised from Australian government ownership by 2006. Market capitalisation was approximately A$54.9-55 billion as of 24 July 2026.

What happened in Telstra's July 2026 outage?

On 10 July 2026 a software/GPS-timing fault unpatched since 2022 caused about 45% of mobile sessions to fail at peak and 604 Triple Zero emergency call errors nationwide, triggering a Senate inquiry, an ACMA investigation, and civil penalty exposure of up to A$30 million.

Who is Telstra's biggest competitor?

Optus, owned by Singtel, is Telstra's largest rival with roughly 28-30% Australian mobile market share as of July 2026, well behind Telstra's 40-48%. TPG Telecom is third with 15-23% and is suing Telstra over allegedly exaggerated coverage maps.

Is Starlink a threat to Telstra?

Not yet. As of mid-2026 SpaceX's Starlink is Telstra's partner, not a competitor, via a June 2025 direct-to-cell satellite texting launch on Samsung Galaxy S25. Analysts flag Starlink's trajectory toward direct-to-consumer mobile service as a long-term watch item for Telstra's rural coverage moat.

The call

Telstra's network scale and regulatory standing keep it ahead of Optus and TPG, with AI so far reshaping its cost base rather than its customer base.

Telstra runs Australia's largest telephone and internet network, covering 99.7% of the country with physical infrastructure and government licenses that would take competitors a decade or more to build from scratch. Optus and TPG are smaller rivals fighting for market share, and Starlink's satellite internet could eventually threaten rural coverage, but neither is close to replacing Telstra's core business in the next few years. A massive network outage in July 2026 hurt the company's reputation and brought regulatory fines, but the penalties are tiny compared to Telstra's annual earnings, so the real question is whether angry customers will switch to competitors or whether new rules force the company to share its network with rivals at cut-rate prices.

Why

AI pressure: None apparent. AI hits Telstra as a cost tool, not a rival: the Accenture data/AI joint venture is being wound down, cutting 209 jobs. Could AI do the core job? Unlikely.

Bigger players: Starlink direct-to-cell (SpaceX). Currently a Telstra partner for remote coverage, but satellite-to-phone service could later bypass carriers in rural areas. Could a giant copy it? No, they are blocked.

What protects it. 99.7% population coverage, owned spectrum, and critical-infrastructure status give Telstra a physical network rivals can't quickly copy.

What would change this call

Optus or TPG report subscriber gains in H2 2026 results tied to the July 2026 outage. Would show rivals converting Telstra's outage into real market share loss.
ACMA's August 2026 report and outcome of the Universal Outdoor Mobile Obligation Bill vote. Would show whether regulation re-rates Telstra's coverage moat into a cost burden.
Starlink launches direct-to-consumer mobile service in Australia at price parity. Would show satellite moving from partner to genuine rural competitor.

Key numbers

FY25 EBITDA A$8.6b, up 14.3% (2025-06-30)
Mobile market share 40-48% vs Optus 28-30% (2026-07-07)
Market cap A$54.9-55b (2026-07-24)

Named risks

Regulatory and legal fallout from July 2026 outage, including ACMA report due August 2026 and Senate inquiry. Severity: high
A second major network outage within 12 months could trigger structural re-rating. Severity: high
Starlink shifting from satellite-messaging partner to direct-to-consumer rural mobile competitor. Severity: medium
Continued job cuts via Infosys outsourcing and AI restructuring straining service delivery and union relations. Severity: medium
Universal Outdoor Mobile Obligation Bill could impose new coverage-reliability regulatory regime. Severity: medium
