- ACCC will release a draft decision on NBN Co’s replacement module in March 2026, with a final ruling expected in June.
- The review may redefine basic broadband and reshape wholesale pricing for retailers.
- Changes could influence broadband plan availability and pricing throughout 2026 and 2027.
The next major shift in Australia’s fixed broadband landscape is already in motion, with NBN Co preparing for a pivotal regulatory milestone slated for mid-2026. Under the national broadband framework, NBN Co is required to submit what is known as a “replacement module application.”
This document shapes the next regulatory cycle by outlining proposed wholesale pricing structures, service standards and the minimum product set that NBN Co must provide to retailers across the country.
Once submitted, the application becomes the foundation for an extensive review process managed by the Australian Competition and Consumer Commission.
The ACCC’s draft decision will set the tone for industry discussions
In March 2026, the ACCC is expected to release its draft decision on NBN Co’s application. This will be the first detailed look at how the regulator interprets NBN Co’s proposals and where it believes amendments may be necessary.
The draft decision typically triggers a period of industry and stakeholder consultation, allowing retailers, consumer advocacy groups and other interested parties to present feedback before the ACCC settles on its final position.
By June 2026, the ACCC aims to hand down its final decision. This ruling will determine the wholesale rules that apply for the next regulatory cycle and will effectively define what NBN retailers can buy and at what cost. Historically, these decisions have far-reaching implications, shaping everything from the level of competition in the retail market to the availability of certain speed tiers.
Changes could reshape the definition of basic broadband
One of the most closely watched aspects of the replacement module process is how the ACCC and NBN Co approach entry-level services. The review may alter what qualifies as “basic broadband” in Australia, and this could influence the minimum speeds and data allowances that consumers can expect from the lowest-cost plans.
Any adjustments to the definition of basic service levels tend to have a ripple effect, improving service quality for some customers while potentially shifting prices for others.
Another significant area under scrutiny is wholesale pricing. The cost structure that the ACCC ultimately endorses will influence the operating conditions for retail service providers. If wholesale charges rise or fall, retailers may adjust their plan pricing accordingly.
This means consumers could see changes across the market in late 2026 and into 2027, ranging from revised entry-level plans to reshaped mid-tier and high-speed offerings.
What this means for consumers in 2026 and beyond
For most households, the replacement module decision may seem like a technical behind-the-scenes regulatory process, but its outcomes are likely to influence the practical experience of choosing a broadband plan.
Service quality benchmarks could shift, retailers’ cost structures could be rebalanced and the competitive landscape may change as well. All of this can affect the affordability and availability of plans across the country.
