Questions Raised About NBN Co’s Fibre ARPU Forecasts

NBN Co’s forecasts for average revenue per user (ARPU) growth up to FY33 are being evaluated. HoustonKemp, a consultancy working with the ACCC, has voiced skepticism about these estimates, potentially jeopardizing certain of NBN Co’s upgrade investments.
Examination of NBN Co’s Spending
The consultancy analyzed NBN Co’s expenditures from the last three years and projected for the following three, determining whether they were “prudent and efficient.” HoustonKemp contested several aspects of network enhancements, proposing that portions of the copper network could have been retained longer without updates.
Issues Concerning Fibre Upgrades
HoustonKemp highlighted concerns that NBN Co’s investments in the fibre network are outpacing customer needs, questioning the validity of the anticipated ARPU increase for fibre subscribers. Their evaluation proposes that the expected ARPU rise may be exaggerated.
ACCC’s View on NBN Co’s Capital Spending
The ACCC has signaled its intent to approve a reduced capital expenditure for the upcoming three years relative to what NBN Co proposed. The ACCC’s preliminary assessment indicates a total forecast capital expenditure of $6.9 billion for the 2027–29 period, which is 18.2% lower than NBN Co’s initial proposal.
Investments in Technology
HoustonKemp found no issues with NBN Co’s intended spending on technology, including AI and automation, confirming that the technology investment plan emphasizes cost effectiveness.
Conclusion
NBN Co is facing examination over its anticipated ARPU growth, with apprehensions regarding the prudence of swift fibre upgrades. While the ACCC recommends lower capital expenditures, the majority of NBN Co’s spending has been approved as effective.
