The national broadband network will make Australia the world's first fully-connected continent, according to the man in charge of the rollout.

"By 2020, we'll be the first country of our size to make broadband access universal," NBN Co chief executive Bill Morrow says in a speech to be delivered on Friday.

"In the next three years, NBN will put Australia ahead of the world for high speed, universal broadband access."

The federal government has committed to ensuring the network provides download rates of at least 25 megibts per second for all Australians, which is well below current world standards, though many users will have access to much greater speeds.

Mr Morrow said companies should be considering how to make the most of the NBN to grow thier operations, urging them to get their "NBN strategy in shape".

"How can you ensure the NBN network is the catalyst for your business, and not just the catalyst for your competition," he says in the speech to be delivered at an Australia-Israel Chamber of Commerce lunch in Sydney.

"This is the conversation we need to be having right now."

NBN Co recently outlined its latest corporate plan, including a 25 per cent increase in its 2020 revenue target to $5 billion.

The improved revenue forecast was attributed to an expected 30 per cent jump in data consumption and strong take-up by businesses as the NBN roll-out gathers pace.

NBN Co is on track to connect eight million premises by 2020, up from three million now.
