ACCC launches review into regulation of superfast fixed-line broadband

The Australian Competition and Consumer Commission (ACCC) has officially begun a regulatory review into the future of the superfast broadband access service (SBAS), opening the inquiry in November 2025.

This is a significant development because SBAS regulation underpins how many internet providers gain access to high-speed fixed-line networks across Australia.

The review aims to assess whether the current rules are still fit for purpose in a broadband market that has changed dramatically over the last few years. With new internet technologies becoming more widely available, the ACCC is examining whether enforced regulation remains necessary to maintain fair competition or whether natural market forces are now strong enough to keep pricing and service quality in check.

This inquiry marks a major milestone for the industry, as it may influence how Australians access and pay for high-speed internet well into the future.

What the SBAS covers

The superfast broadband access service (SBAS) applies to fixed-line broadband networks that can deliver download speeds of 25 Mbps or higher. This includes many modern networks designed to support streaming, online learning, cloud services, and high-demand household usage.

SBAS regulation ensures that these networks are accessible to a wide range of retail service providers (RSPs), rather than allowing network owners to restrict access or charge excessively high wholesale fees. Without this regulation, some ISPs might struggle to compete, which could limit consumer choice and potentially drive up retail prices.

In simple terms, SBAS helps maintain a level playing field so customers can choose from multiple providers offering competitive plans and prices, regardless of who owns the underlying network.

Why the ACCC is reviewing the rules

The ACCC is reviewing SBAS regulation because the broadband market is evolving faster than ever before. New technologies such as 5G home internet, enhanced satellite services, and low Earth orbit (LEO) satellite broadband are beginning to rival or even outperform some fixed-line networks. These alternatives are becoming increasingly appealing to households, especially those in areas where traditional networks haven’t kept pace.

As more customers switch to alternatives, the ACCC is questioning whether fixed-line broadband still requires the same level of regulatory protection. This review invites public and industry feedback on whether current competitive pressures are strong enough to keep prices fair and ensure that broadband services remain accessible.

The inquiry is a proactive step to future-proof Australia’s telecommunications framework by ensuring regulation aligns with how people actually connect to the internet today - and in the years ahead.

What this could mean for consumers and ISPs

The SBAS declaration is set to expire on 28 July 2026, meaning the ACCC’s decision will likely land next year. Depending on the outcome, several changes may occur:

Impact on wholesale pricing

If regulation is reduced or altered, network operators may gain more freedom over wholesale pricing structures. This could result in price adjustments that flow through to internet plans offered by retail providers.

Changes to competition

Deregulation may affect smaller ISPs that rely heavily on wholesale access to compete with larger providers. If wholesale costs change, some smaller companies may need to adjust their offerings, restructure pricing, or even reconsider service areas.

Potential flow-on effects for customers

Consumers could see changes to plan prices, speed tiers, or service availability. While increased competition from wireless and satellite options might help keep retail prices stable, a shift in regulation could still influence how ISPs package and price their plans.

Influence on infrastructure investment

The decision may also shape the future of fixed-line network investment. If regulation becomes less stringent, network owners might be more motivated to upgrade or expand infrastructure - but this will depend on market dynamics.

While the impacts are still uncertain, the ACCC’s final decision is expected to play a major role in shaping the broadband landscape from 2026 onward.
