Optus

History

AUSSAT and deregulation (1981–1990) Optus can trace its beginnings back to the formation of the Government-owned AUSSAT Pty Limited in 1981. In 1982, Aussat selected the Hughes 376 for their initial satellites, with the first, AUSSAT A1, launched in August 1985. AUSSAT satellites were used for both military and civilian satellite communications, and delivering television services to remote outback communities.

Optus

With Aussat operating at a loss and with moves to deregulate telecommunications in Australia, the government decided to sell Aussat, coupled with a telecommunications licence. The licence was sold to Optus Communications – a consortium including: logistics firm Mayne Nickless (24.99%); UK telecommunications company Cable & Wireless (24.50%); US telecommunications company BellSouth (24.50%); AIDC Limited (10.00%); insurance and investment company AMP (10.00%); and insurance and investment company National Mutual (6.02%).

Optus

The new telecommunications company was designed to provide competition to then government owned telecommunications company Telecom Australia, now known as Telstra.

Founding of Optus (1991–present)

Optus gained the second general carrier licence in January 1991.

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 did not 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 1998, consumers have the choice of preselecting their preferred long-distance carrier or dialling the override code before dialling a telephone number.

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

Optus was the main sponsor of the 1997 ARL season.

2022 cyberattack

Around 22 September 2022, Optus systems sustained a significant cyberattack that resulted in a major data breach of both current and former customers' personal information, including customers’ names, dates of birth, phone numbers and email addresses, with a smaller subset of customers having their street addresses, driving licence details and passport numbers leaked. Optus CEO Kelly Bayer Rosmarin urged customers to exercise "heightened awareness" regarding transactions with their Optus and other accounts. Rosmarin emphasised that passwords were not compromised. The CEO said that the "worst-case scenario" regarding the number of customers whose data had been leaked was 9.8 million customers, but believes the actual number to be far lower.

On 24 September 2022, Australian news outlets The Age and The Sydney Morning Herald reported that Optus was investigating the authenticity of a ransom demand of US$1 million made on a hacking forum. The demand gave Optus one week to pay the ransom in cryptocurrency else the data will be sold for US$300,000 to whoever else wants it.

On 6 October, the Australian Federal Police announced the arrest of a 19-year-old man who had allegedly threatened 93 Optus customers by saying that he would use their information leaked in the attack to commit financial crimes, unless they paid AUD $2,000.
