The Darwin-Jakarta-Singapore Cable (DJSC) system is subsea cable connecting Australia (Perth, Darwin, Port Hedland, Christmas Island), Indonesia and Singapore.

The DJSC system is created by linking two existing cables: the Australia Singapore Cable (ASC) to the North West Cable System (NWCS), with an addition of 1000km cable from Port Hedland to the main trunk of the Australia Singapore Cable (ASC) and additional cost of AU$100million.

DJSC, ASC and NWCS are owned and operated by Australian operator Vocus. 

The DJSC system delivers 40Tbps of capacity between Australia and Asia, unlocking Darwin as a major new data hub for the Asia-Pacific and opening up the Pilbara mining region for low-latency connectivity into Singapore.

The DJSC system will interconnect with the in-progress terrestrial cable from Geraldton to Port Hedland under Vocus’ Project Horizon.
