Cairns’s next broadband leap: what’s on the roadmap for 2027 and beyond

Cairns residents can expect a wave of connectivity upgrades over the next 18 months, with at least two major network operators quietly advancing fibre and wireless projects that promise to push typical home speeds beyond 1 Gbps and plug coverage gaps in the city’s northern suburbs.

The push comes as the Australian Competition and Consumer Commission’s latest quarterly broadband report, released on 8 July 2026, showed that Cairns still lags behind Sydney and Melbourne in the proportion of premises connected to full‑fibre NBN services: 41 percent here versus 57 percent in the capital cities. With fibre‑to‑the‑node still accounting for a third of local connections, both NBN Co and TPG Telecom have flagged investments aimed at closing that gap by the end of 2027.

Fibre‑to‑the‑premises expansion map

NBN Co’s current fibre‑extension program, which began rolling out in Cairns in March 2026, is targeting another 14,000 premises in suburbs including Manoora, Manunda and the western edge of Smithfield. The company confirmed on 10 July that it will begin the detailed design phase for a further 8,000 homes in the northern beach corridor between Palm Cove and Port Douglas before Christmas. Those areas are currently served by fibre‑to‑the‑node or hybrid‑fibre‑coaxial, and residents have complained of peak‑hour congestion during the 2025‑26 wet season.

Meanwhile, TPG Telecom announced on 2 July that it is trialling XGS‑PON technology on its existing fibre network in the Cairns CBD and around the Cairns Hospital precinct. The trial, which covers roughly 300 business and residential connections, delivers symmetrical speeds of up to 2 Gbps. TPG network head Michelle O’Neill told an industry briefing in Sydney last week that a city‑wide rollout would depend on demand, but early data from the trial shows that 22 percent of participating households upgraded to the 1‑Gbps tier within the first four weeks.

Wireless backhaul and public Wi‑Fi

On the mobile side, Optus is midway through a $12 million upgrade of its backhaul capacity at the Earlville and Mount Sheridan tower sites, aiming to support the growing number of 5G fixed‑wireless customers in the southern corridor. The upgrade, contracted to Nokia and scheduled for completion by November 2026, will boost aggregate capacity at each site to 80 Gbps-enough to handle simultaneous 4K streaming for roughly 5,000 devices per tower.

The Cairns Regional Council is separately scoping a tender for a free public Wi‑Fi network covering the Esplanade from Fogarty Park to the Reef Hotel Casino. A draft request for proposal, published on the council’s website on 9 July, envisions 25 outdoor access points tied to existing light poles, with a targeted launch date of April 2027. The network would sit alongside the existing free Wi‑Fi in the Cairns Convention Centre and the Botanic Gardens.

For businesses and residents wondering what to do next, the clearest signal is that fibre‑to‑the‑premises availability will expand patchily. NBN Co’s rollout schedule, updated fortnightly on its website, is the best way to check if a specific street is in the next construction wave. For those in the TPG trial zone-roughly bounded by Lake Street, Florence Street and Aplin Street-upgrading to the 2‑Gbps service is possible now, though the telco warns that pricing is still provisional at $149 per month until the trial concludes in December.

None of these projects will deliver a uniform city‑wide boost overnight. But taken together, the roadmap points to a Cairns in 2028 where gigabit home connections are the baseline rather than the exception, and public spaces finally shed their reputation as dead zones for mobile data.
