There are ongoing concerns that NBN's fibre service will be more expensive than existing copper-based ADSL2+ connections.

Currently there are not enough safeguards to ensure consumers, particularly pensioners and small businesses, will not be sold short, according to Mazerski.

"There should be some policy decisions that say people such as pensioners have to be left alone in terms of price and should be given some sort of allowance to do the [NBN installation] work in their houses so they are not out of pocket or paying for something they don't want," he said.

Small businesses that rely on fax machines -- which operate on copper phone lines - should also be given allowances to upgrade their equipment, Mazerski said.

There should not be a forced fibre scenario, but if there is, customers should be properly compensated, he said.
