From London: Telstra has quietly halted the expansion of its low earth orbit satellite backhaul programme for remote mobile base stations in Australia, after its constellation provider failed to deploy enough spacecraft to maintain reliable service. The pause, confirmed by a Telstra spokesperson to iTnews, comes as outage data reveals a sharp deterioration in service quality across the remote mobile network, with emergency communications among the casualties.
The programme relies on Eutelsat's OneWeb LEO constellation to replace older geostationary satellite links at roughly 200 small cell mobile base stations serving remote Australian communities. Telstra chief executive Vicki Brady acknowledged the situation at the carrier's half-year results presentation last week, confirming the rollout had reached only a relatively small number of sites before being put on hold.
"Their rollout of their satellite constellation hasn't gone as planned on their side. It does mean today there are some issues particularly impacting voice. However, in terms of data performance, we have seen significant improvements," Brady said.
A Telstra spokesperson clarified the position further: the carrier has paused further conversions from geostationary to LEO backhaul while it waits for additional OneWeb satellites to enter service. The data performance gains from the technology are real, Telstra maintains, but the current constellation density is insufficient to sustain the voice quality the network requires.
The consequences of those reliability problems have been anything but abstract. The number of mobile tower outages deemed to have a significant community impact rose from 3,614 in 2024 to 5,221 in 2025, a period that coincides almost precisely with when Telstra began shifting remote sites onto the OneWeb service. In the two years prior, 2022 and 2023, outage figures had remained relatively stable. Telstra has attributed the increase in part to coverage gaps in the OneWeb constellation, which it says cause base stations to lose reliable voice connectivity for periods of roughly 10 to 15 minutes, twice per day.
For people living and working in remote Australia, those windows are not an inconvenience. They are a safety risk. Better Internet for Rural, Regional and Remote Australia (BIRRR), a community advocacy group, disputes Telstra's characterisation of the outages as isolated and brief. BIRRR says callers are frequently losing voice communication even when their handsets show a satellite connection, suggesting the problem is more pervasive than the carrier's figures indicate.
The most serious documented case involves a roadhouse at Tirranna Springs in Queensland. Owner Jil Wilson told iTnews that in September last year she attempted to call triple zero after a staff member was badly burned when a car battery exploded. The triple zero operator could not understand her due to voice dropouts on the line. Wilson was eventually able to get an ambulance dispatched, but only after working through several alternative communication options and drawing on her local knowledge of hospital contacts in the area. Queensland Ambulance Service later confirmed it received a call that resulted in an ambulance taking a man to a healthcare facility approximately 30 kilometres from the roadhouse for burns treatment.
There is a legitimate counterargument to any straightforward criticism of Telstra here. The shift from geostationary to low earth orbit backhaul represents a genuine technological advance, and the data performance improvements Brady cited are not marketing spin. LEO satellites sit far closer to Earth than geostationary craft, dramatically reducing signal latency and increasing throughput. For remote communities that have long suffered with sluggish data services, this matters enormously. The problem is not the technology itself but the pace of constellation build-out, which is Eutelsat OneWeb's responsibility to resolve, not Telstra's alone.
That said, the decision to migrate live emergency-capable infrastructure to a constellation that had not yet reached operational density was a risk management call, and the outage figures suggest it was made too early. Whether Telstra adequately stress-tested voice reliability before committing remote communities to the new backhaul is a fair question for regulators and the Australian Communications and Media Authority to examine.
The political dimension is sharpening. BIRRR co-founder Kristy Sparrow is expected to address a regional telecommunications policy event in Canberra hosted by CommsDay, alongside Mike Johns, senior manager of the satellite working group within the Australian Telecommunications Association. The gathering reflects growing pressure on industry and government to treat remote connectivity as critical infrastructure, not a commercial afterthought.
The Tirranna Springs incident cuts to the heart of what is genuinely at stake. In urban Australia, a degraded voice call is a frustration. In outback Queensland, it can determine whether help arrives at all. Telstra's decision to pause further rollout is prudent, but it does not address the sites already converted. For those communities, the wait for a fuller constellation is not an abstract technology timeline. It is the daily reality of uncertain access to emergency services, and that deserves a more urgent response than a half-year results footnote.
