A section of Wagga about eight kilometres across and six kilometres north to south, including parts of Tolland, Bourkelands and Tatton, is listed by NBN Co as 'build commenced'.

However, the estimated completion date for fixed-line services has been moved from September 2019 to as late as June 2020.

Springvale resident David Schulz said fibre optic lines had been installed in his area, including up most of his driveway to an NBN-branded cable pit.

"They have sent me a lot of emails but I haven't been connected yet," he said.

"I'm not that bothered as I've heard people say the NBN isn't all it's cracked up to be."

One Kooringal business manager, who asked not to be named, said the situation was "terrible".

They said the business had been told their copper-line phones would be turned off in September but had been given no date for when the NBN would arrive.

An NBN Co spokesperson said the network was being rolled out "as quickly and efficiently as possible".

"Construction to connect more than 7000 homes and businesses in parts of Kooringal, Lake Albert, Bourkelands, Tatton, Tolland and Springvale is underway and are expected to be able to be able to connect progressively from January next year through to June," the spokesperson said.

The spokesperson said building the NBN was "one of the most complex and ambitious initiatives to be undertaken in Australia".

"While we would like to connect everyone at the same time, the sheer size of the country and the complexity of the build means that this is not possible and we ask the community for its patience as we make the transition from the old to the new network," they said.

Though the Kooringal and Lake Albert suburbs will see its new internet service connected later than other Wagga areas, many households will receive faster connections via the new 'Fibre to the Curb' technology.

Fibre to the Curb allows shorter distances between individual houses on existing copper wires and connections to the fibre optic network.

An NBN Co spokesperson said the Kooringal, Springvale and Lake Albert areas would receive a "a mix of Fibre to the Node and Fibre to the Curb technologies".

Fibre to the Node connections, which are common in other areas of Wagga, involve connecting individual household copper phone lines to green metal cabinets placed on nature strips every few hundred metres.
