Optus
Optus is Australia's number two mobile and broadband carrier, wholly owned by Singtel.
The call
Optus turns a profit and keeps its licenses, but a Singtel stake sale, court dates, and Telstra's AI spending all land before the FY27 results are in.
Optus is one of Australia's three main phone and internet providers, owning towers, network lines, and radio frequencies that are expensive to build from scratch, which normally protects it from new competitors. Right now it is weaker than rival Telstra because Telstra is spending heavily on AI-powered customer service while Optus is still hiring contact-center workers the old way, and because Optus had a massive network failure in September 2025 that triggered lawsuits, a $100 million fine, and massive staff changes. The biggest wildcard is whether Optus' parent company, Singapore-based Singtel, will sell its stake to a new owner, which could bring either fresh investment or more chaos during an already unstable turnaround period.
Why
01
AI pressure: Generic AI customer-service agents (industry-wide adoption trend). AI bots now clear 60-80% of telecom tickets elsewhere, yet Optus just added 300 human contact-centre roles post-outage. Could AI do the core job? Unlikely.
02
Bigger players: Telstra. Telstra holds ~44% share versus Optus's ~31% and has committed USD 800M to AI-optimized network build-out with no Optus match yet. Could a giant copy it? No, they are blocked.
03
What protects it. Spectrum licenses, tower and fibre assets, and mandated 000-carrier status keep Optus locked into Australia's three-player oligopoly.
What would change this call
Whether Singtel announces a binding minority-stake deal for Optus. Shows if Optus gains a stabilizing local anchor investor or remains adrift.
Outcome of the OAIC Federal Court penalty case and the June 2027 class-action trial. Indicates how much further financial and reputational damage Optus absorbs.
Whether Optus suffers another major network outage within 12 months. Would show whether reliability problems are structural, not one-off.

Questions people ask
- Is Optus profitable in 2026?
- In FY26 (year ended March 31, 2026), Optus reported operating revenue of A$8,345 million, EBITDA of A$2,356 million, and EBIT of A$550 million, up 23.1% year over year, per its May 20, 2026 results release, though parent Singtel absorbed a roughly A$400 million exceptional loss tied to regulatory provisions.
- Who owns Optus?
- Optus is wholly owned by Singapore's Singtel, which is itself 51% owned by Temasek Holdings, the Singapore government's investment arm, as of September 25, 2025. Singtel disclosed in May 2026 it is open to selling a minority stake in Optus to an Australian partner.
- Could AI replace Optus customer service jobs?
- Optus added 300 Australian contact centre roles after its September 18, 2025 Triple Zero outage, even as industry reporting from April 2026 described AI agents resolving 60-80% of support tickets elsewhere, showing Optus is currently expanding, not automating, this labor-heavy layer.
- Is Telstra Optus's biggest competitor?
- Yes. Telstra led Australia's telecom market with roughly 44% share versus Optus's 31% as of a January 27, 2026 Mordor Intelligence report, and Telstra committed USD 800 million over four years to AI-optimized networks, an investment scale Optus has not matched publicly.
- Did the Optus data breach lead to legal action?
- Yes. Australia's OAIC filed a Federal Court civil penalty case on August 11, 2025 over the 2022 breach affecting about 9.5 million Australians, and a Slater & Gordon class action is set for trial starting June 7, 2027, with mediation ordered by November 21, 2026.
- Will Singtel sell Optus?
- Singtel disclosed in May 2026 it is open to selling a meaningful minority stake in Optus to an Australian partner, after a 2024 attempt to sell 20% to Brookfield lapsed; as of July 16, 2026 the process was reported as active with no binding deal yet announced.
