Telecommunications refer to the electronic means of transmitting information across distances. This information can take various forms, including voice calls, data, text, images, or video. In contemporary society, telecommunications facilitate the organization of both local and remote computer systems into cohesive networks.

The telecommunications sector is a component of the broader information and communication technology industry, encompassing companies that deliver telecommunications and internet services. This sector is engaged in the development, distribution, storage, and enhancement of information products, as well as the infrastructure necessary for the transmission and storage of such information.

In Australia, the telecommunications landscape features key players such as: 

  • Telstra, Optus, and TPG: Prominent carriers that deploy their technology on communication towers.
  • National Broadband Network (NBN): An infrastructure provider that supplies fiber and fixed-line networks

The Australian Communications and Media Authority (ACMA) oversees the telecommunications industry, ensuring that service providers adhere to established codes registered with the authority.
