Early History

After privatisation, AUSSAT became Optus and its first offering to the general public was to offer long distance calls at cheaper rates than that of its competitor Telstra. The long distance calling rates on offer were initially available by consumers dialing 1 before the area code and phone number. Following this, a ballot process was conducted by then regulator AUSTEL, with customers choosing their default long distance carrier. Customers who made no choice or refused to respond to the mailout campaign automatically remained as a Telstra long distance customer. Customers who remained with Telstra could dial the override code of 1456 before the area code and phone number to manually select Optus as the carrier for that single call. Since 1 July 1997, consumers have the choice of preselecting their preferred long distance carrier or dialling the override code before dialing a telephone number.

The group began by building an interstate fibre optic cable and a series of exchanges between Optus' interstate network and Telecom
Telstra

's local network. It also laid fibre optics into major office buildings and industrial areas, and focused on high bandwidth local, (interstate) long distance, and interstate calls for business. In its early years, Optus was only able to offer local and long distance calls to residential customers connected to Telstra's local phone network. Telstra would carry residential to residential calls to Optus' exchanges, and then the calls would be switched to Optus' long distance fibre optic network.

The Hybrid Fibre-Coax Rollout

These practices meant that Optus was (and still is) the single largest customer of their competitor, Telstra. To become competitive Optus would need to lay its own local phone network. To provide a killer application
