Landcom's Ashton Grove estate has been revealed as one of the first greenfields sites to receive an active National Broadband Network service.
Fibre rollout in the estate, located at East Maitland in the NSW Hunter region, had already begun.
NBN Co had previously been tight-lipped about which of the approximately 1,600 applications it had received from housing developers would be first to get fibre infrastructure.
The first active broadband services in new housing estates were to be trialled from August 8.
It was not the first time a Landcom estate had been involved in an NBN-related project.
Last year, the developer's Parkbridge estate in Sydney's west was chosen by the NSW Government for a six-month trial of apps that could take advantage of 100 Mbps speeds.
Parkbridge had been cabled by Opticomm.
"Our Parkbridge estate was selected to test the federal government's National Broadband Network (NBN)," the company said in its 2009/10 annual report.
"It was chosen because it is the one of the few areas in Australia which is already 'NBN ready', thanks to Landcom's foresight in laying optic fibre conduits in the early stages of the development."
