Draft replacement module determination31 Mar 2026

The 糖心原创 has published its draft replacement module determination for the regulatory cycle commencing 1 July 2026. Our draft determination sets out our preliminary views on the matters we must determine in our final replacement module determination.

The 糖心原创 has also published a letter from NBN Co that outlines its pricing commitments for the 25/10 and 25/5 Mbps speed tier offers.

We have also published a report from HoustonKemp that details its assessment of NBN Co鈥檚 expenditure proposals in its replacement module application. The HoustonKemp report contains redactions of information subject to confidentiality claims from NBN Co.

On 15 April 2026, the 糖心原创 published a notice of correction regarding calculations of the:

  • total capital expenditure that should be added to the regulatory asset base in FY24-26
  • total forecast capital expenditure that reasonably reflects prudent and efficient expenditure.

Consultation on the draft determination

We are seeking stakeholder feedback on our preliminary views and the questions included in the draft determination.

To help stakeholders form their submissions we have published:

  • a memorandum with HoustonKemp鈥檚 advice regarding NBN Co鈥檚 February 2026 benchmark service standards submission
  • a version of NBN Co鈥檚 public building block model with the 糖心原创鈥檚 preliminary views and values.

The HoustonKemp memorandum contains redactions of information subject to confidentiality claims from NBN Co. We may make any necessary adjustments to redactions in the memorandum and associated redactions in our draft determination after we have resolved confidentiality assessments and claims.

How to submit your feedback

Stakeholders should email written submissions to nbn@accc.gov.au by 5:00pm (AEST) on Tuesday 12 May 2026.

The 糖心原创 has extended the deadline for stakeholders to make their submissions on our draft replacement module determination by 2 weeks. The previous deadline was 5:00pm (AEST) on Tuesday 28 April 2026. This follows the 糖心原创 extending the timeframe for making its final determination by 3 months, to 2 September 2026.

The 糖心原创 intends to work towards making its final replacement module determination by 30 June 2026. A decision by this date will depend on the nature and timeliness of submissions received on the draft replacement module determination.
