In a statement, the company said 70% of new plans being taken up were either 50Mbps or higher.
Orders for the higher speed plans had almost tripled, from 16% to 44%, NBN Co said, without specifying the figure on which these percentages were based.
It also claimed that "average bandwidth network congestion reduced from more than five hours to less than 30 minutes per service, per week compared to this time last year (excluding Sky Muster satellite)".
“It’s important for people connecting to the NBN Co access network to understand how to pick a speed tier and retail plan that suits their needs.
“We recommend people talk to their internet provider about the actual speeds they are likely to experience, particularly during peak times and choose a plan that supports the number of people, usage habits and devices in the home.
“Our latest progress report shows in the last year we have also improved our ability to work with internet providers to restore faults on the network within our agreed time frames by 30%. We know there is more work to be done and will continue to collaborate with the industry as the rollout gathers pace.”
