Singtel Optus Pty Limited is an Australian telecommunications company headquartered in Macquarie Park, a suburb in the Northern Sydney region of Sydney, New South Wales, Australia. It is a wholly owned subsidiary of Singaporean telecommunications company Singtel.

Optus is the second-largest telecommunications company in Australia, with over 11 million customers as of 2023. Its mobile network covers 98.5% of the Australian population, with plans to cover 100% of Australia by 2025 through its partnership with SpaceX.{{Cite web |title=Together Optus and SpaceX Plan to Cover 100% of Australia |url=https://www.optus.com.au/about/media-centre/media-releases/2023/07/together-optus-and-spacex-plan-to-cover-100-percent-of-australia |access-date=12 April 2024 |website=Optus |language=en}}

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.{{cite web | title = Aussat A-Series | work = Australia's Satellites & Programs | publisher = Lowdown | url = http://www.lowdown.com.au/sat_assat.html | access-date = 2007-06-16 |archive-url = https://web.archive.org/web/20070608034807/http://www.lowdown.com.au/sat_assat.html |archive-date = 2007-06-08}} AUSSAT satellites were used for both military and civilian satellite communications, and delivering television services to remote outback communities.

{{see also|Optus fleet of satellites}}

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:{{cite book|title=Report 333 - The sale of Aussat|date=September 1994|publisher=The Parliament of the Commonwealth of Australia – Joint Committee of Public Accounts|isbn=0-644-35468-2|pages=12}}

  • 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%).

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.[http://www.theaustralian.com.au/business/technology/optus-rings-up-20-years-sticking-to-its-guns/news-story/d357df679f5db28b7a09184e0f27ee9f Mitchell Bingemann, (30 January 2012), Optus rings up 20 years, sticking to its guns, The Australian] Retrieved 9 February 2017

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.{{cite news | last = Zucker | first = Paul | title = Australia's Telecom apologizes for misleading ads | publisher = Newsbytes News Network | date = 1993-06-04 | url = http://findarticles.com/p/articles/mi_m0NEW/is_1993_June_4/ai_14017101 | archive-url = https://web.archive.org/web/20081014084416/http://findarticles.com/p/articles/mi_m0NEW/is_1993_June_4/ai_14017101 | url-status = dead | archive-date = 2008-10-14 | access-date = 2007-06-05 }} 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.

1n 1993 Optus, along with Telstra and Vodafone were licenced by the regulator Austel (now ACMA) to provide 2G GSM mobile telephony. Optus's mobile service launched in May of that year.{{cite web |url=http://3gwiz.com.au/ozmobilenet/?page_id=24 |website=A History of Cellular Mobile in Australia |access-date=2025-04-18 |title=History | Oz MobileNet }}

In 2024, Singtel held advanced talks with Brookfield to sell a 20% stake in Optus. Brookfield and Singtel were unable to agree on terms, with Singtel claiming afterwards it remained committed to Optus and the Australian market.{{Cite web |date=3 April 2024 |title=Singtel Says No Optus Deal After Report Brookfield Talks Ended |url=https://www.bloomberg.com/news/articles/2024-04-03/singtel-s-optus-sale-talks-with-brookfield-collapse-australian |access-date=12 April 2024 |website=Bloomberg |language=en}}

Other wholly owned subsidiaries of note no longer have a significant active role as individual entities. These are as follows:

Reef Networks was formed in 1999 to provide an optical fibre link between Brisbane and Cairns in Queensland. Optus gained exclusive access to this link in 2001, ahead of acquiring the organisation in 2005.{{cite news | title = Optus buys Reef | publisher = ZDNet Australia | date = 2005-03-31 | url = https://www.zdnet.com/home-and-office/networking/optus-buys-reef/ | access-date = 2007-06-04 | archive-date = 6 May 2007 | archive-url = https://web.archive.org/web/20070506200902/http://www.zdnet.com.au/news/communications/soa/Optus-buys-Reef/0,130061791,139186609,00.htm | url-status = live }}

{{unreferenced section|date=June 2012}}

These practices meant that Optus was the largest customer of Telstra. To become competitive Optus would need to lay its own local phone network. To provide a killer application for this, the Australian Federal government sold subscription television licences. Optus, as well as the Seven Network, businessman Kerry Stokes and American cable company Cablevision, formed the Optus Vision consortium. News Corporation and Telstra created the rival Foxtel consortium.

Telstra's local phone network did not have the capability to deliver Foxtel pay television to consumers in the early 1990s, so Telstra identified a need to create a broadband network to support this new product.

As Telstra and Optus could not agree on terms for a joint broadband cable roll out, they laid two competing cable networks, in addition to Telstra's existing copper network, at a combined cost estimated of over A$6bn.

Whilst Telstra focused on creating a broadband network specifically for broadcast, Optus designed their cable network to provide telephony services in addition to broadcast television.

Optus is no longer a customer of Telstra's after deciding to move the funding used to lease Telstra's copper network into constructing their hybrid fibre-coaxial network, the first in Australia.

{{Main|OPEL Networks}}

In June 2007, joint venture subsidiary OPEL Networks was awarded government funding towards the cost of building a regional broadband network. Optus was to be contracted to build the network on behalf of OPEL.{{cite web|title=Broadband Access and Choice for rural and regional Australia |publisher=OPEL / Elders |date=2007-06-18 |url=http://www.futuris.com.au/images/presentations/presentation_38.pdf|access-date=2007-07-14 |url-status=dead |archive-url=https://web.archive.org/web/20070830203938/http://www.futuris.com.au/images/presentations/presentation_38.pdf |archive-date=30 August 2007 }}

In April 2008, after a change of the Federal Government from the Liberal Party of Australia coalition to the Australian Labor Party, the new government terminated the funding agreement and the project was halted, with its functions to be replaced by the National Broadband Network.

Early on 8 November 2023, an undetermined issue caused a nationwide outage in Optus Mobile and Fixed Internet services. The outage directly impacted more than 10 million customers, including government services, hospitals and businesses. Optus Mobile customers reported that their phones showed 'SOS' on the signal indicator, which is a sign the regular network is down, but mobile phones still have access to alternate networks in the event of an emergency call by using a so-called camping mechanism; however, Optus landlines were unable to make emergency triple-zero calls.{{Cite news |date=2023-11-07 |title=What caused the Optus outage, and when will it be fixed?
