The ACCC hinted that the non-NBN fibre networks could be transferred to the NBN when it issued its prices for non-NBN high-speed Internet services on Friday.
The determination covered Telstra's fibre network at its South Brisbane exchange area and estates with Velocity fibre.
The ACCC said that Telstra’s fibre networks were subject to different pricing arrangements due to the cost of separating these networks from Telstra’s legacy network systems "and the prospect that the fibre networks may be transferred to the NBN".
The source, who has spent 40 years in the telecommunications industry working on the technical side of things, said he was aware of five communities at the northern end of the Gold Coast who had Velocity fibre.
In the past, the ACCC has also earned criticism for deciding that there would be 121 points of interconnect to the NBN, with smaller ISPs saying that this favoured the larger companies in the space.
