Estates of under 100 premises — approximately half of the greenfield market, according to NBN Co — will likely receive copper wiring from Telstra, which remains provider of last resort for smaller estates. Quigley said fibre provision to ineligible greenfields would fall under the standard rollout timetable.

NBN Co has provided specifications for the infrastructure required for fibre deployment, but is yet to recommend suitable conduits and pits for installation, instead providing “generic dimensions” to developers.

Quigley said he didn’t the company would not buckle under influx of submissions.

“We’re trying to make sure we keep this process as straightforward and simple as possible for the developers and we’ve been working very closely with them for some time,” he said. “I think it’s fair to say they’re pretty happy with the outcome and the way this will be carried out.

“We don’t yet have a network out there, so this is not an easy job to do.”
