The universal mobile service obligation bill, which obliges the three major carriers to deliver voice and text service across up to 5 million square kilometres of Australia, cleared the House of Representatives this week.
What the legislation requires
The measure mandates that Telstra, Optus and TPG Telecom provide competitive mobile voice and SMS coverage in remote and underserved areas. The default start date is set for December 2027, though the law includes a discretionary clause allowing the communications minister to grant exemptions where necessary.
During the lower‑house debate, Victorian crossbencher Helen Haines secured an amendment that forces the government to publish the reasons behind any use of those discretionary powers. A second set of amendments she proposed—targeting low‑income consumer access, fault‑rectification processes and temporary disaster roaming—was rejected, with communications minister Anika Wells saying existing laws already cover those issues.
Wells also noted that the industry is on track to roll out temporary disaster roaming this October, ahead of the natural disaster season, as part of a joint initiative.
Carriers push back on technology timeline
All three operators argue that the satellite‑to‑mobile (STM) technology needed to reach the most remote locations is not yet commercially viable. Telstra said the bill should not start until low‑earth‑orbit constellations and compatible handsets are available on market‑ready terms.
They emphasized that a critical mass of devices capable of talking to satellites must exist before large‑scale service can be guaranteed. TPG’s chief technology officer Giovanni Chiarelli echoed that sentiment, stressing the need for a sufficient number of compatible handsets. Optus CTO Sri Amirthalingam told a Senate committee earlier this year that the technical, commercial and regulatory pieces required to meet the obligations “safely and in a sustainable fashion” would not be in place by the slated date.

The firms highlighted that STM services are required only where current mobile coverage is absent or poor, and that LEO satellite networks are still being deployed worldwide.
TPG has formally asked that the start be moved to 2030, while Telstra suggested replacing the fixed date with a ministerial direction based on technology readiness, a factor that will only become clear closer to the deadline.
The debate reflects a tension between policy ambitions to close the digital divide and the practical rollout schedules of emerging satellite systems. Even as governments push for nationwide connectivity, the pace of handset development and satellite launch schedules often lags behind legislative timelines. This gap can shape how quickly remote communities actually see reliable service.
For people living in isolated towns and outback stations, the legislation aims to ensure that a simple phone call or text message no longer depends on expensive satellite phones or intermittent radio links.
Senate scrutiny expected
Although the bill cleared the lower house, it now faces a potentially tougher test in the Senate. Greens communications spokesperson Sarah Hanson‑Young and coalition senator Sarah Henderson have signaled intent to introduce further amendments, particularly concerning domestic roaming rights in regional areas.
The Department of Communications has previously told industry outlets that the bill already contains measures to address many of the concerns raised by the firms, but the upcoming Senate debate will likely determine whether additional safeguards are inserted before the law takes effect.
