A new plan to install an underwater ‘super-cable’ for high-speed internet traffic is expected to bring faster internet speeds to Western Australia.

The new line, capable of transmitting data at near light speed, is expected to be 40 times more efficient than its 20-year-old predecessor, allowing for the simultaneous streaming of millions of movies.

Connecting Perth to Singapore, the installation of the new underwater cable will commence in March with an expected completion date of mid-2019.
