What the ACCC can't do

Industry reporting and monitoring

Telecommunications monitoring

We collect information to monitor competition, track market developments, and inform regulatory decisions. We publish reports using the data and information we collect.

Telecommunications registers

The registers contain a public record of certain telecommunications information. This includes exemption orders, competition notices, determinations, declared services and access undertakings.

Access to infrastructure services

National Broadband Network (NBN) access regulation

We regulate the wholesale National Broadband Network (NBN) service. This service is used by retail service providers to provide broadband services to consumers. We determine the terms and conditions of access to services provided over the NBN.

Non-NBN fixed line services access regulation

The ACCC regulates a range of non-NBN fixed line wholesale telecommunications services. For the services we regulate, we determine the price and other terms of access for retail service providers.

Internet interconnection regulation

Internet interconnection refers to the arrangements networks make with each other to exchange internet traffic. We monitor and assess whether access to internet interconnection services is available on competitive terms.

Mobile services regulation

The ACCC actively monitors the mobile services market and regulates mobile terminating services. We do this to stop mobile operators abusing their monopoly over mobile termination and to help make mobile services competitive for consumers.

Telstra's migration of fixed line services

The ACCC assesses compliance with Telstra’s structural separation undertaking and migration plan. We monitor consumer issues and competition while Telstra’s legacy fixed line services are being migrated to the National Broadband Network (NBN).

Copyright regulation

The granting of copyright usually doesn’t cause competition concerns. There have been some instances, however, where collective copyright licensing has resulted in market power. We have an interest in copyright when it impacts competition.

Digital radio access regulation

The ACCC regulates access to digital radio transmitter facilities through access undertakings. We also ensure digital radio multiplex transmitter licensees don't discriminate anti-competitively between broadcasters.

ACCC inquiries and market studies into telecommunications

Mobile services inquiry 2026-27

On 5 August 2026, the ACCC started a combined public inquiry about proposals to declare the 2 services: a domestic roaming service and a radio access network service.

Regional mobile infrastructure inquiry 2022-23

In March 2022, the ACCC was directed to conduct an inquiry into towers used in the supply of radiocommunications services in regional areas, and into the feasibility of providing mobile roaming during natural disasters and emergencies.

Communications sector market study 2018

The ACCC conducted a market study of the Australian communications sector to examine any existing and emerging competition and consumer issues in the sector. The final report was released in April 2018.
