The three year roll-out plan includes areas where the network is active, where construction is currently underway and where work will commence within the next three years. The estimated number of premises covered in this roll-out plan has increased by over 2.7 million premises on the figures released in the January update to the one year roll-out plan.
Most of the growth in premises covered in the roll-out plan comes in areas where work has already started.
This is because NBN Co has said it needs to manage the roll-out of the network as efficiently and cost-effectively as possible, and deploy contractor resources in a logical, sequential way.
It is estimated that the average time from work commencing to NBN services being available is 12 months.
NBN Co is also building fibre infrastructure in over 230 new developments spread across 180 locations nationally and comprising over 21,000 premises.
