"I don't think it should be a cookie cutter [strategy] and I don't think fibre is for everybody," he said.

Installing fibre in Greenfield estates make sense since there are no existing customers to disrupt, but areas with high numbers of pensioners should be considered, according to Mazerski.

"You look at each area and you do an analysis to decide whether the cost outweigh the customer nuisance," he said. "You might have some instances where it costs more not to shut the copper down but because of certain situations and to please a large group of customers, it makes to just do it that way."

Mazerski claims NBN Co has not done enough to engage with customers to find out what they want.

He proposed doing surveys or polls on customers to find out who actually wants or needs a fibre broadband connection.
