The Commonwealth Bank will be a key part of the NBN’s rollout, providing finance and technology assistance to build the next generation of telecommunications infrastructure.

The Bank will provide funding of up to $200 million for the NBN, as well as other support such as providing a range of technologies, technology services and other services to support the rollout.

The NBN is a national fibre-optic network that uses satellites to transmit high-speed internet to the entire country.

The project is expected to cost about $60 billion.

The announcement comes just weeks after Communications Minister Mitch Fifield announced the Commonwealth will fund $1 billion of the project.

The bank has previously backed the Government’s plans for the rollout, which were announced in May.

The $1bn has been secured through an arrangement with Australian Communications and Media Authority, which manages NBN Co’s telecommunications services.

The new funding, however, comes after the Government announced the completion of its first rollout.

On Friday, Fifield said the Government will spend $1.6 billion on the project, which will be completed by December 2021.

“We’re going to do a very successful NBN rollout.

We’re going in the right direction,” he said.

“And the next thing is the $1billion, so that we can have that final piece of the puzzle.”

The rollout is due to be completed within two years.
