This audit would assess the effectiveness of NBN Co Limited’s (NBN Co’s) strategies to manage its transition from building to operating the national broadband network (NBN).

While NBN Co will continue to have a build commitment for new developments and complex connections, construction of the NBN ‘volume rollout’ was scheduled for completion by June 2020, followed by a further 18 months for completing the migration from previous infrastructure to the NBN. The transition of NBN Co’s operating model from network construction to one focusing on ongoing network operations was identified as a key risk in the NBN Co’s Corporate Plan 2020–2023.
