New subsea cable to improve Australia–Thailand internet traffic

A new subsea cable called TalayLink is being built to connect Australia and Thailand. The goal is to expand international internet reach and provide a more stable connection in Asia Pacific and beyond.

The name comes from the Thai word for “sea.” TalayLink will link to the interlink cable announced last year under the Australia Connect initiative. It will take a route through the Indian Ocean, west of the Sunda Strait, rather than following the crowded paths where most cables already run. The new route is meant to give Thailand another connection point and support future data centres and a cloud region planned for the country.

Alongside the cable, there are plans for two new connectivity hubs – one in Mandurah, Western Australia, and another in South Thailand. The hubs are meant to support the region’s long-term internet capacity needs and help deliver digital and AI services by handling tasks like cable switching, content caching, and colocation.

The Mandurah site will serve as an alternative landing point to Perth, which is where most subsea cables in Western Australia currently come ashore. In South Thailand, the project will move faster through a partnership with colocation provider AIS, which already has infrastructure in place.

The TalayLink cable will serve as a pivotal piece of digital infrastructure, enhancing Thailand’s connectivity and resilience. Together with Google’s upcoming Google Cloud region and data centre in Thailand, these forward-looking investments will significantly expand the regional network and computing capacity, while firmly positioning Thailand as a important digital gateway for next-generation cloud and AI innovation in Southeast Asia.

“The Thailand Board of Investment (BOI) is fully committed to supporting Google’s investment in Thailand, fostering the growth of the nation’s digital economy, and advancing digital skills to ensure inclusive and sustainable development,” said Narit Therdsteerasukdi, Secretary General, Thailand Board of Investment (BOI).

Once TalayLink and the hubs are running, they will help strengthen internet networks in Australia, Africa and Southeast Asia. Together with earlier hubs planned for the Maldives and Christmas Island, these links will add new ways to connect in the Indian Ocean and onward to the Middle East.

The projects also support goals set in Western Australia’s digital future plan and the Thai government’s push for economic transformation through AI and wider digital access. The company behind the work says it aims to help drive economic and social growth in Australia, Thailand and Southeast Asia by building stable and reliable internet infrastructure.
