One Year of NBN Speed Upgrades: Assessing the Impact on Australian Broadband

One year after the launch of NBN Co’s 'Accelerate Great' program, Australia’s fixed-line broadband network has successfully handled a significant increase in internet speeds. The initiative, which debuted in September 2025, introduced substantial upgrades, including boosting the NBN 100 tier to 500Mbps and the NBN 250 tier to 750Mbps, alongside a new multi-gigabit 'Home Hyperfast' option. Data from the Australian Competition & Consumer Commission (ACCC) indicates that despite the massive jump in bandwidth, the network has remained stable. While average performance percentages relative to plan speeds saw a minor statistical dip, the actual throughput increased dramatically, confirming that the infrastructure—particularly fiber-to-the-premises (FTTP)—is capable of supporting these higher speeds during peak hours. The NBN 500 tier has rapidly emerged as the most popular choice for households, signaling a successful transition to a faster digital landscape for Australian consumers.
