Australia is about to attempt something no country has tried before: legally obliging mobile carriers to deliver outdoor voice and SMS coverage across an entire continent, with Low Earth Orbit (LEO) direct-to-handset satellites filling the gaps that terrestrial towers cannot reach. The Universal Outdoor Mobile Obligation (UOMO), first announced by then-Communications Minister Michelle Rowland in November 2024 and now progressing through the parliamentary process, reframes services like SpaceX's Starlink Direct-to-Cell from optional add-ons into regulated components of universal service. It is an ambitious, innovation-friendly response to a genuine market failure — but it also concentrates national connectivity risk in ways that deserve careful scrutiny.
The Problem UOMO Is Trying to Solve
Australia covers roughly 7.7 million square kilometres but has fewer than 27 million people, most clustered on the eastern and southern coasts. Mobile network economics simply do not justify towers across vast tracts of the outback, and the existing Universal Service Obligation (USO) — a legacy framework built around copper landlines and Telstra's payphone fleet — has long been criticised as inadequate for a mobile-first country. Black Summer bushfires in 2019-20 and successive cyclone seasons exposed how quickly rural communities lose contact when terrestrial networks fail. The Bean Review into regional telecommunications, delivered in late 2024, recommended replacing the analogue-era USO with a modern, mobile-oriented obligation that takes advantage of new satellite capabilities.
UOMO is the policy response. Rather than subsidising more towers in commercially unviable locations, it requires the major carriers — Telstra, Optus and TPG — to ensure that anywhere a customer can stand outdoors in Australia, a standard 4G/5G handset can at minimum place a voice call and send an SMS. The only realistic way to meet that obligation across the continent is via direct-to-handset satellite, and both Telstra and Optus have already announced commercial partnerships to deliver it: Telstra with Starlink, and Optus separately with SpaceX's Direct-to-Cell service.
Why This Is the Right Instinct
For an editorial position that favours pro-innovation, proportionate regulation, UOMO has a lot to commend it. It is technology-neutral on its face — any LEO operator that can meet the performance standard could in principle qualify — and it leverages private investment rather than reaching for public subsidies as the first lever. It treats satellite-to-handset not as an exotic niche but as a maturing layer of the mobile ecosystem, which is exactly what regulators around the world will need to do as constellations from SpaceX, AST SpaceMobile, Lynk Global and others come online.
It also avoids the trap of trying to pick a winner. By setting an outcome (outdoor voice + SMS, continent-wide) and letting carriers choose their satellite partner, the policy preserves competitive pressure on Starlink, which is otherwise the dominant incumbent in the LEO direct-to-cell space. The Australian Communications and Media Authority (ACMA) retains regulatory authority over the carriers; what changes is that those carriers' compliance now depends on non-terrestrial network (NTN) infrastructure they do not own.
The Hard Problems Parliament Still Has to Solve
That last point is where the proportionality questions get serious.
- Single-supplier dependence. If, in practice, both Telstra and Optus rely on the same US-based constellation, Australia's national mobile resilience floor effectively becomes a function of SpaceX's commercial decisions, regulatory standing in the US, and operational availability. That is a sovereignty exposure that any responsible policymaker should hedge against — through diversity-of-supply requirements, interoperability standards, or reserved spectrum for alternative constellations.
- Spectrum coordination. Direct-to-cell services reuse terrestrial mobile spectrum from orbit. ACMA's existing framework for spectrum allocation was not designed with NTN reuse in mind, and cross-border coordination with New Zealand and neighbouring jurisdictions raises live questions the ITU is still working through.
- ACMA's authority over orbital assets. The regulator can fine an Australian carrier, but it cannot order a satellite operator headquartered in Hawthorne, California to maintain a particular service level over Cape York. The enforcement chain has to run through the carrier, which means contract terms — not regulation — ultimately set the resilience floor.
- Emergency services interoperability. Triple Zero call handling, location accuracy, and lawful intercept obligations all need to be re-engineered for a hybrid terrestrial-NTN environment.
A Reasonable Middle Path
None of these problems is fatal, and none is a reason to abandon UOMO. They are reasons to legislate it carefully. A workable version would: set an outcome-based standard rather than mandating a specific technology; require carriers to demonstrate supplier diversity or credible substitutability within a defined transition period; give ACMA clear authority to demand uptime and incident reporting from carriers about their satellite partners; and reserve spectrum bands and licensing pathways that keep the door open for non-Starlink LEO entrants.
Australia is, characteristically, moving first on a hard problem. If Canberra gets the framework right, UOMO will be a template other geographically vast democracies — Canada, Brazil, India's remote regions — quietly copy. If it gets it wrong, it will have outsourced a piece of critical national infrastructure to a single foreign operator under the language of universal service. The next twelve months of drafting will decide which.
