The long-awaited event in Gungahlin will be accompanied by fanfare and Labor politicians.

Today's roll-out will be in Palmerston, with work in the central business district of Gungahlin due to be completed by Christmas.

Although the NBN Co's website has shown for months that work had commenced in Amaroo and Ngunnawal, the contractor had not begun laying the fibre optic cable for the high-speed network.

A recent update by the company said work would be completed in those suburbs by May next year.

Labor Senator Kate Lundy said with the fibre hauling commencing today, NBN Co forecast that construction activity should be complete in the central business district of Gungahlin as well as nearby suburbs by the end of the year.

The federal government has given more than $1 million to Gungahlin Library through the ACT government to ensure local individuals and businesses can access training opportunities and connect with local services using the NBN in publicly available facilities.

Member for Fraser Andrew Leigh said he was particularly excited about the opportunities the NBN opens up in education.

''With superfast broadband, students will be able to video link with schools overseas and share classroom experiences to learn other languages in real time,'' he said.

''Businesses will be able to upload and download enormous files quickly.

''It means the person running the small production company can email a draft version of an ad, rather than posting a DVD or waiting until a meeting to screen it.''
