What changes occurred with the NBN speed upgrades?
One year ago, Australia’s National Broadband Network (NBN) implemented a major upgrade initiative that boosted fixed-line internet speeds for millions of households connected via fibre to the premises (FTTP) and hybrid fibre coaxial (HFC). The move raised popular speed tiers fivefold or more—for example, the 100Mbps Home Fast plan increased to 500Mbps, and the 250Mbps Home Superfast tier tripled to 750Mbps. Higher tiers had their upload speeds doubled, and a new multi-gigabit Home Hyperfast tier was introduced, offering up to 2,000Mbps download speeds.
This upgrade represented one of the largest adjustments to Australia’s fixed-line broadband capacity, promising substantial speed gains for eligible customers.
Did the network handle the increased speeds effectively during busy periods?
Data collected by the Australian Competition & Consumer Commission (ACCC) shows the fixed-line NBN coped well with the higher speed demands. Although speed percentages relative to plan speeds saw a small decline—from delivering roughly 102% of 100Mbps plans pre-upgrade to about 99.4% of the new speeds a year later—the absolute speeds delivered were much higher post-upgrade.
For example, FTTP customers on the new 500Mbps tier averaged just over 500Mbps during peak evening hours, confirming that the infrastructure and network stability were ample to support the speed boosts without major performance degradation. HFC users similarly saw strong performance near advertised speeds.
These results indicate that the network hardware and design, especially FTTP connections, were largely ready to handle the acceleration, providing reliably fast broadband when demand is typically highest.
How did user adoption and reliability trends evolve following the upgrade?
The upgrades quickly shifted the mainstream broadband speed preference among Australians. The usage of the 500Mbps tier surged, replacing the once-dominant 100Mbps plans for many. Millions of households moved up to plans offering 100Mbps or faster speeds within months.
Importantly, this surge was not accompanied by a noticeable increase in network outages or reliability issues. Outage rates remained consistent with historical levels, suggesting that enhancing speed limits did not compromise the network's robustness.
What limitations or challenges have emerged for users?
Despite the overall success, around 5.6% of fixed-line connections were classified as underperforming about a year after the upgrade, an increase from roughly 3% before the speed boosts. While underperforming services were historically linked to fibre-to-the-node (FTTN) connections, recent data shows that some FTTP and HFC customers also experience slow speeds relative to their plans.
One key reason is the limitation imposed by customer-side equipment. Many homes may still use older or lower-spec routers, cables, or networking hardware that cannot effectively support speeds above 100Mbps. Moving from 100Mbps to 500Mbps makes such equipment a critical bottleneck, preventing users from realizing the full benefit of their upgraded NBN plan, especially over Wi-Fi.
Therefore, the new speed tiers have shifted the focus for some households to their internal networking gear as the next upgrade priority.
What should current NBN users consider going forward?
For users still on lower-speed plans—such as the 50Mbps tier—with eligible FTTP or HFC connections, it’s advisable to explore upgrading to faster NBN plans. The jump from 50Mbps to 500Mbps in particular offers a significant improvement in bandwidth capable of supporting multiple simultaneous streams, gaming, large downloads, cloud services, and remote work demands.
To fully exploit these speed improvements, investing in compatible networking equipment, like high-performance routers designed to handle gigabit speeds, will be essential for avoiding internal bottlenecks.
Additionally, popular 500Mbps plans—such as those offered by Exetel and Kogan Internet—are competitively priced and have been shown to often exceed advertised speeds, making them strong candidates for upgrading households.
Key takeaway for Australian broadband users
The acceleration of NBN fixed-line speeds one year ago marked a transformative step in Australian home internet, with most users experiencing substantially faster and still reliable broadband. While the network infrastructure, particularly FTTP, handled the increased speeds successfully during peak hours, the primary user challenge today lies in ensuring in-home equipment keeps pace with these upgrades.
For households aiming to maximize their upgraded NBN plan benefits, reviewing and updating routers and internal network cabling may be necessary. This will help unlock the full advantage of the faster tiers, enabling smoother streaming, gaming, downloads, and remote work.
Overall, the shift to higher-speed NBN plans represents a critical evolution for modern Australian homes using multiple connected devices and demanding data-intensive applications.
