People who complain about not being able to get connected to the national broadband network should be sent to the back of the connection queue, according to NBN Co non-executive director Michael Malone.

Mr Malone  –  founder of internet service provider iiNet, which was acquired by TPG in 2015 – was referring to "NBN Service Class 0" customers. They are stuck in broadband limbo because of an arbitrary decision set in law that prevents Telstra from connecting customers who should have already been connected to the NBN but haven't been.

"If I was running NBN and they [complaining Service Class 0 customers] went to the media, I would put them to the back of the queue. Personally, that's what I would do," Malone said, adding that Service Class 0 issues would all get resolved and that people should be patient.

"iiNet used to get 20,000 support calls a day and very few ended up on the front page," Mr Malone said.

"NBN is installing 45,000 customers per week and that will double in the next 12 months," he added, noting that the NBN was always going to suffer from "faults along the way".

"Think about how you would roll out the network if you needed to hit 10 million households," he said. "What are you going to do first? You do all the easy ones first and then the others."

While he said Telstra and NBN needed to resolve the Service Class 0 problem soon, Mr Malone agreed that people should be able to connect to existing ADSL while problems remained.

"I don't understand why they [Telstra] can't connect you to the DSL they had yesterday," he said. "There's no reason why they can't."
