The Australian Labor Party will not make any quick changes to the rollout of the national broadband network if it comes to power in the Federal Election later this year, but will take a "responsible" approach to the project.

The Australian Labor Party has described as "ridiculous" a claim made by the government that the NBN Co — which released its half-yearly results on Monday — was continuing to exceed its targets.

Testing of broadband speeds by the ACCC has shown that fibre-to-the-premises and hybrid fibre coaxial connections deliver about 86% to 87% of plan speeds during busy hours — 7pm to 11pm — compared to about 79% for fibre-to-the-node connections.
