The Coral Sea Cable System (CS2)


The Coral Sea Cable System will link both PNG and Solomon Islands back to the major East Coast Internet Hub at Sydney.  Each country will be able to use 2 fibre pairs on the system from their respective capitals, Port Moresby and Honiara to Sydney, yielding each country up to 20 Terabits/s.

The Landing Party selected for the Sydney Landing is Telstra and the system will be installed in their Paddington Exchange in Sydney. The submarine cable will make landfall at Tamarama Beach in Sydney’s Eastern suburbs and utilise Telstra land duct across Sydney to Paddington. The physical cable will have a 4 fibre optic pair core sheathed in the one cable from Australia over 2500 km to a Branching Unit in the Coral Sea, where the 4 pair core is then split into two cables each containing 2 fibre pair cores that make their way to Landing Stations in Port Moresby and Honiara.

The project is being co-funded by the Governments of the Commonwealth of Australia, PNG and Solomon Islands under the terms of an MOU signed on 11th July 2011. Australia is grant funding 66.7% of the total cost with the remainder being contributed by Solomon Islands and PNG.

Vocus Communications are the prime contractor under an Engineering, Procurement and Construction Contract (EPC) that was signed on June 18th 2018. Vocus Communications sub-contracted Alcatel Submarine Networks (France) to construct and install the cable system. The project is currently in construction phase and is expected to be completed by the end of December 2019.

The Solomon Islands Government contribution is being made through The Solomon Islands Submarine Cable Company Limited (SISCC). SISCC signed the Solomon Islands Landing Party Agreement with the Commonwealth of Australia on 13th June 2018. Under this Agreement, SISCC are constructing all the landing party infrastructure in Solomon Islands ready for the installation of the cable. An equivalent Landing Party Agreement for PNG was signed between the Commonwealth of Australia and PNG DataCo.

The CS2 cable will be owned and operated by a Special Purpose Vehicle Company based in Australia. It will be owned equally by The Commonwealth of Australia, SISCC and PNG DataCo. PNG DataCo and SISCC will each be granted Indefeasible Rights of Use (IRU) over 2 fibre pairs for the full lifetime of the Cable system (25 years).
