JASURAUS was a 5.332 Gbit/s, 2,800 km optical submarine telecommunications cable that connected Port Hedland, Australia, to Jakarta, Indonesia, with a further interconnection to the APCN and which was decommissioned in 2012.

JASURAUS was conceived in 1995 as an additional link from Australia to provide telephony services connection to the world, with a design life of 25 years and at a cost of A$160 million. The name was derived from a concatenation of the original planned sites of 'Jakarta' - 'Surabaya' - 'Australia'. However the Surabaya landing was abandoned before project commencement, though the name remained.

At time of being ready for service in 1997, the main cables linking Australia to the world were Tasman2 (Sydney to Auckland connecting with Pac Rim East and continuing to Hawaii) and Pac Rim West (Sydney to Guam). Each system consisted of two fibre pairs delivering a total of 560 Mbit/s bandwidth per system. Jasuraus was designed to deliver a dramatic increase in network capacity, and was able to carry nearly 60,000 phone calls simultaneously at a data rate of 5.332 Gbit/s.[1]

JASURAUS was overtaken in 2000 by the 40 Gbit/s SeaMeWe3 and 320 Gbit/s Southern Cross Cable Network, just 3 years after start-up. The new systems provided stiff competition for JASURAUS, due to their higher bandwidth and easy access to systems located in the United States, and ongoing economic concerns proved to be an issue for the primary operators Telstra and Optus throughout the life of the cable.

While JASURAUS was capable of supporting an upgrade to 20 Gbit/s, such agreements would have required consensus from the JASURAUS operators and APCN's owners. Proposed upgrades were further hampered due to the high cost charged by Telstra to third parties for the provision of IP transit and Leased line services from Port Hedland to Perth, which resulted in decreased demand from carriers as there was no alternative communications path out of Port Hedland.

In the absence of upgrades beyond its initial bandwidth, JASURAUS saw minimal further use. Its remaining years were spent largely idle, with the cable retained as a backup link out of Australia and as an additional source of connectivity for AARNet.[2][3]

According to industry sources,[4][5] JASURAUS was decommissioned in 2012.[6]
