The Australian broadband market has been evolving rapidly in recent years, driven by large-scale NBN upgrades that have boosted both speeds and reliability. Speeds are expected to increase even further in the future with the launch of the Accelerate Great initiative in September 2025, which upgrades speed tiers for Fiber-to-the-Premises (FTTP) and Hybrid Fiber-Coaxial (HFC) users from 100 Mbps and 250 Mbps to 500 Mbps and 750 Mbps, respectively, while also introducing a new 2 Gbps tier.

The NBN is investing heavily to upgrade from fiber-to-the-curb (FTTC) and fiber-to-the-node (FTTN) to FTTP, delivering faster speeds and improved service quality for hundreds of thousands of Australian households. The Australian government is also heavily investing in NBN fixed wireless and satellite infrastructure to improve connectivity for 800,000 premises nationwide.

As these upgrades progress, the share of FTTP connections within total NBN wireline connections continues to rise, according to ACCC reports. This shift is fueling greater data consumption and a growing appetite for higher speeds. Australian households are increasingly moving to higher-speed tiers as data demand rises, now averaging around 500GB per month. This trend may accelerate further as the NBN boosts its 100Mbps and 250Mbps plans to 500Mbps and 750Mbps, respectively, for FTTP and HFC connections. However, as our analysis shows, router quality remains critical — with RSP-issued gateways typically outperforming Bring-Your-Own alternatives, helping users fully benefit from NBN upgrades.

Market dynamics are also shifting in Australia. ACCC data shows that major providers such as Telstra, TPG, and Optus — which together control nearly two-thirds of the domestic broadband market — have been losing NBN fixed-line subscribers in recent years. Meanwhile, smaller RSPs such as Superloop, Aussie Broadband, and Vocus are gaining ground, supported by FTTP expansion. Vocus has been particularly active, acquiring TPG’s fiber assets and B2B divisions for AU$5.25 billion (US$3.42 billion).

To offset fixed-line losses, Optus, Telstra, and TPG have been expanding FWA services using their mobile networks. Starlink has also been gaining momentum, now reaching around 200,000 subscribers in Australia — and becoming an increasingly vital connectivity option for remote regions.

In this report, Opensignal examines real-world data from our Australian fixed broadband users — including fixed-line, Fixed Wireless Access (FWA), and satellite connections. To reflect the diverse ways Australians use fixed broadband, we include five key measures of user experience: Consistent Quality, Download Speed, Upload Speed, Video Experience, and Reliability Experience. Together, these metrics capture the wide range of broadband use cases across households — from remote work and online education to streaming video and gaming.

We compare user experience across six major fixed-line retail service providers (RSPs) that deliver services via the National Broadband Network (NBN): Aussie Broadband, Optus, Superloop, Telstra, TPG, and Vocus. We also include three FWA providers — Optus, Telstra and TPG. The data collection period covers a 90-day window starting June 1, 2025, allowing us to assess how these RSPs performed. We also include national scores for fixed-line and FWA RSPs across five Australian cities — Adelaide, Brisbane, Melbourne, Perth and Sydney.

Plan characteristics — such as speed tiers or data caps — vary significantly by provider, and the mix of subscribed plans affects average performance results. Opensignal’s measurements capture the experience users actually receive, regardless of the plan they have purchased. This report analyzes the real-world broadband experience across all user plans. It is also worth noting that a user’s experience can be influenced by the router they use.
