The short version
Key points
- Around 622,000 premises remain on fibre to the node and are scheduled to be upgraded to fibre to the premises by about 2030.
- The fibre upgrade is estimated to cost approximately $3.8 billion.
- Only about $1.723 billion of that cost has been recognised as prudent for future recovery through wholesale prices.
- NBN Co has received government support of up to $3 billion, while NBN Co is contributing about $800 million.
- The upgrade is expected to reduce copper-network operating costs and avoid some future replacement expenses.
Why the NBN cost is being reviewed
NBN Co is continuing the final stage of its network upgrade, replacing remaining fibre-to-the-node connections with fibre to the premises. The transcript says approximately 622,000 premises are still on fibre to the node, with the work expected to be completed by around 2030.
The total cost of the upgrade is estimated at about $3.8 billion. NBN Co sought to classify the spending as prudent investment, which would allow the cost to be recovered through regulated wholesale prices in the future.
The limit on future price recovery
NBN wholesale prices are currently broadly constrained to inflation-linked increases, but the transcript says NBN Co will be able to begin recovering some costs through wholesale prices after mid-2032.
The Australian Government and the ACCC have limited the amount of the fibre-to-the-node overbuild cost that can be treated as prudent. Rather than allowing the full $3.8 billion to be recovered, about $1.723 billion can potentially be included in future pricing. The rest will not be used as a justification for later wholesale price increases under this decision.
Internet providers purchase NBN services at wholesale prices, so changes to those prices can ultimately affect household and business broadband bills. The decision does not prevent all future price increases, but it limits the amount associated with this specific upgrade that can be recovered from customers.
Why the decision was made
The network upgrade is already receiving substantial public support. The transcript refers to government funding of up to $3 billion, with NBN Co contributing about $800 million. Limiting future cost recovery is intended to reduce the risk of customers effectively paying again through higher broadband prices.
NBN Co argued for no cap, or at least a higher cap, on the amount it could recover. Its position included the view that competition and customers’ willingness to pay would discourage excessive price rises. The ACCC and government position described in the transcript instead places a defined limit on the recoverable amount.
The background to fibre to the node
Australia’s NBN originally included a plan to deploy fibre to the premises more broadly. Following a change of government in 2013, the network adopted a mixed-technology approach that relied heavily on fibre to the node, alongside technologies including hybrid fibre coaxial and fibre to the curb.
The current replacement program means some of that earlier fibre-to-the-node investment is being followed by another major construction project. The transcript describes this as a consequence of choosing technology that was expected to be faster and cheaper to deploy at the time, but which now requires substantial upgrading.
Potential savings from replacing copper
The upgrade is not only about improving access to full fibre. The transcript says copper-based fibre-to-the-node infrastructure degrades by around 4% to 6% per year in performance and may eventually struggle to meet the minimum 25 Mbps speed standard in some areas.
Replacing the remaining fibre-to-the-node connections is expected to reduce maintenance requirements. Government estimates cited in the transcript include approximately $85 million in annual operating savings and more than $300 million in avoided future copper upgrades. These savings may help offset some of the project’s cost over time.
TechManPat’s conclusion
I see the cap as a reasonable safeguard against customers being charged twice for the same network transition: first through public funding and NBN Co’s contribution, and later through higher wholesale prices. The fibre rollout should continue, but limiting recovery to about $1.723 billion recognises that not every cost from the earlier fibre-to-the-node path should automatically be passed on to broadband users.
