Fast promises, hard questions: Canberra’s broadband boom tests trust and privacy

Canberra’s broadband network is getting a serious upgrade, but not everyone is cheering.

Starting next month, NBN Co will begin switching on full-fibre connections for another 40,000 homes in the inner south and Woden Valley, part of a national plan to retire the ageing copper network by 2028. The rollout promises symmetrical gigabit speeds-download and upload-for the first time in most of those suburbs. But as the infrastructure goes in, so do questions about cost, equity and surveillance.

“The technology itself is remarkable,” said Associate Professor Lin Chen, a telecommunications policy researcher at the Australian National University. “But the conversation we’re not having is about who owns the data flowing through these pipes and what safeguards exist when speeds let surveillance scale in ways we haven’t seen before.”

Speed vs. privacy: a familiar tension

The tension is not new. In May, the Los Angeles Police Department let its contract with surveillance giant Flock expire, citing “serious concerns” over civil liberties and privacy. Flock’s automated licence-plate readers, which feed real-time location data into law enforcement databases, had drawn criticism from civil‑rights groups for enabling warrantless tracking. Canberra has no municipal deal with Flock, but the ACT government has been trialling automated number‑plate recognition on light-rail corridors and major arterial roads since late 2025.

“Every time we add a sensor-a traffic camera, a Wi‑Fi hotspot, a fibre node-we’re also adding a potential surveillance point,” said Chen. “The ethical question isn’t whether the technology works. It’s whether the governance around it can keep pace.”

That governance is patchy. Australia’s Privacy Act is under review, but proposed reforms-including stronger enforcement powers for the OAIC and a statutory tort for serious invasions of privacy-have stalled in federal Parliament since early 2025. Meanwhile, the ACT government is progressing its own Human Rights Act amendments that would embed privacy protections into local law, though the timeline remains unclear.

Who gets left behind?

Beyond privacy, the rollout exposes a digital divide that runs through Canberra’s geography. Suburbs in the inner north and south-home to higher proportions of public‑service professionals and university staff-are already covered by fibre‑to‑the‑premises. Many households in Belconnen, Tuggeranong and Gungahlin still rely on fibre‑to‑the‑node or fixed‑wireless connections, where top speeds top out at 100-250 Mbps. The upgrade schedule prioritises areas where NBN Co says it can achieve the highest “take‑up density,” a metric that critics argue disadvantages lower‑density and lower‑income neighbourhoods.

“The economics of fibre deployment tend to favour streets where you can connect a dozen homes from a single pit,” said a former NBN project manager who spoke on condition of anonymity because they still consult for the industry. “If you live in a cul‑de‑sac with five houses, you might wait years-unless you’re willing to pay for a custom installation, which can cost thousands.”

NBN Co has said it aims to make fibre available to “at least 90 per cent of Australian premises” by 2028, but has not published a specific timetable for every Canberra suburb. A spokesperson said the company was “working closely with ACT government agencies to align deployments with planned roadworks and development approvals.”

For the roughly 8 per cent of Canberra households that rely on fixed‑wireless or satellite-concentrated in new estates on the city’s fringes like Denman Prospect and Jerrabomberra-the upgrade gap is even wider. Those connections are not included in the fibre‑replacement program at all.

What happens next depends on politics as much as engineering. The federal government has allocated $2.4 billion over four years to complete the fibre upgrades, a figure that assumes stable construction costs and no major supply‑chain disruptions. Both assumptions look fragile given global inflation and semiconductor shortages.

For residents waiting for faster speeds-or worrying about what faster speeds might mean for their privacy-the advice from consumer advocates is straightforward: ask questions. The ACT Council of Social Service is urging households to check their NBN connection type at the government’s MyBroadband portal and to lodge comments with the OAIC if they have concerns about data handling by ISPs or local councils.

“The technology is coming,” said Chen. “The question is whether we build in the guardrails before or after the problems show up.”
