New South Wales is facing a long wait to get a real NBN in place.

Key points:NBN Co is to have to make major changes to the state’s network by 2020The state’s Government is working to deliver a ‘one-stop-shop’ NBN by 2020New South Wales needs to deliver 100% of the network by 2025The Government is now working to find ways to help state governments build their own NBN network.

Key point:The State Government says it needs a ‘stretch of the NBN’ of at least two yearsThe Federal Government has already started laying the groundwork for the construction of a fibre-to-the-node network in New South.

“It’s not only about delivering the network.

We’ve got to get it to people in the state, and the first thing we need to do is to make sure we can get it done in a realistic timeframe,” State Premier Gladys Berejiklian said.”

If we don’t, it’s going to be a real problem.”

Ms Berejivian said she was “dissent” with the state Government’s approach to the rollout of the state-owned NBN Co, which she said had “failed in many respects”.

“We have a lot of work to do, and we have a long way to go,” she said.

In a statement on Monday, NBN Co’s chief executive Greg Hywood said the state would need “tens of thousands of new premises” to reach 100% fibre-optic by 2025.

“Our focus has always been to deliver the fastest, most reliable network possible, and it has been a challenge for us to deliver on that promise,” he said.

The State’s NBN rollout has been “fraught with difficulties” and the State Government is “working tirelessly” to get the NBN up and running, Mr Hywood added.

“We’ve made great progress, but we still have work to be done.”

The Federal government has already begun laying the ground for the NBN network, with a number of infrastructure projects being developed.

The Government’s first priority is to build fibre to the node network in the Northern Territory, which will deliver 100 per cent of its network by 2022.

“The Government has taken a few significant steps in the first few months of the year to get this done,” Mr Hywoods said.

New South Australia’s State Government has set aside $1.6 billion to fund the NBN, which is expected to cost about $500 million over the next four years.

It has committed $1 billion towards the Northern Territories project.
