The Indigo subsea cable system is ready to be deployed by AARNet, Google, Indosat Ooredoo, Singtel, Superloop's SubPartners and Telstra, the consortium announced.
The news comes five months after the completion of the installations of both Indigo Central and West as announced.
With 4,600km of subsea fibre optic cables from Singapore to Perth and another 4,600km from Perth to Sydney, consortium partners are now able to independently take advantage of the new cable system to upgrade their networks and enable capacity increases on demand.
The cable can support up to 36 terabits per second, the equivalent of simultaneously streaming millions of movies a second.
According to Telstra head of international Oliver Camplin-Warner, the system will deliver faster connectivity to customers as well as improve reliability.
"Our vast subsea network is a key part of our international growth strategy and we will continue to invest in additional capacity to meet our customers’ increasing demand for data and maintain our network leadership in the Asia-Pacific region," Camplin-Warner said.
The Indigo Central installation, which connects Sydney to Perth, was completed in 24 December, only three days after Indigo West, which connects Singapore to Sydney, was completed, on 21 December.
Ooi Seng Keat, Singtel's VP carrier services, group enterprise, said the completion will accelerate the roll-out of next-generation technologies that rely on low latency and high-bandwidth connectivity such as high-definition video, autonomous vehicles, internet of things and robotics applications.
"This will bring us closer to realising the benefits of a hyper-connected future and allow us to enhance our services to Singtel and Optus customers, reinforcing our position as the leading provider of international data services in the region," he said.
Superloop CEO Drew Kelton said that Indigo Central supplements its metropolitan fibre networks.
"When combined with the international capacity and inter-connectivity to Singapore and Hong Kong, our strategy to virtualise businesses across the Asia Pacific region is now being realised.”
Meanwhile, AARNet expects the new subsea system to ensure that Australia and its partners in Asia have the international connectivity they need to deliver "excellence in research and education for many decades to come", said CEO Chris Hancock.
During the past five months, the cables went into a period of acceptance and commissioning testing before going live and providing commercial service.
"Part of Google's global infrastructure investments to improve connectivity, we're excited that Indigo will enable faster and more reliable services for users, as well as boost business capabilities between South East Asia and Australia," said Ashish Ahuja, global network infrastructure at Google.
Combined, Indigo West and Central have 9,200km of two-fibre pairs which will be able to support up to 36 terabits per second.
"Indosat Ooredoo is excited with the commissioning of INDIGO. It will be diversifying our international connections across Australia and the fast-growing Southeast Asian market, serving demand increase of data traffic and expanding opportunities for our both customers, corporate and retails consumers," Indosat Ooredoo CTIO Dejan Kastelic said.
It supports our vision to become a leading digital telecommunications company by providing world-class data connectivity and also to support Indonesia’s digital economy growth.”
In April 2017, AARNet, Google, Indosat Ooredoo, Singtel, SubPartners and Telstra entered into an agreement with Alcatel Submarine Networks (ASN) to build the international subsea cable system connecting Singapore, Indonesia and Australia.
On the same day, publicly-listed Superloop announced plans to acquire SubPartners in a US$2.5 million deal.
