Part XIC of the Trade Practices Act 1974 establishes an access regime which allows third parties to gain access to services that are necessary inputs in providing telecommunication services to endusers. Under the regime, the ACCC can declare carriage services and services which facilitate the supply of carriage services. These services are known as ‘eligible services’. The ACCC is in the process of conducting a number of public inquiries into whether to declare certain eligible services under Part XIC of the Act. Should the ACCC make the declarations, the rules and regulatory processes in Part XIC of the Act will apply to the eligible services covered by its decisions.
