The company charged with building the national broadband network will adjust to any changes the federal opposition makes to the project if it wins the September election.

Opposition Leader Tony Abbott and communications spokesman Malcolm Turnbull have outlined major changes to the government’s plans for the NBN.

The opposition believes its plan will deliver a faster and better NBN that will cost $30 billion, compared to $37.4 billion under the government’s plan to provide fibre optic cable to homes.

NBN Co head of products and sales John Simon says that while the company has not started considering the implications of a coalition government, it would work closely with whichever major party wins the election.

“We implement policy so whatever the policy will be of the party that wins the election we will work closely with them,” he told delegates at the CommsDay summit on Tuesday.

“From my personal perspective, it is not about the technology – you can build broadband networks using different technologies.

“You just need to understand the implications of those technologies based on the policies that you want.”

Mr Simon said there were about 50,000 premises that had signed up for a broadband internet plan delivered by the NBN through either fibre, fixed wireless or satellite.

Of those whose NBN service was delivered by fibre, about one third of users were choosing the highest speed plan with a download speed of 100 mega bits per second.

Another third chose broadband plans between 25Mbps and 50Mbps, while the remainder took out the lowest speed 12Mbps plan.

“That’s well above the model we have in our corporate plan,” Mr Simon said.

The coalition plan was for download speeds of between 25 and 100 Mbps by the end of 2016 and 50 to 100 Mbps by 2019.
