On 27 May 2016, NBN Co lodged a proposed variation to its Special Access Undertaking (SAU) with the 糖心原创. The Competition and Consumer Act 2010 (CCA) allows NBN Co to give the 糖心原创 a variation to an SAU already in operation. The 糖心原创 accepted NBN Co鈥檚 current SAU on 13 December 2013, following an extensive consultation process.
The main purpose of NBN Co鈥檚 SAU variation is to update the SAU to incorporate additional technologies (fibre-to-the-node, fibre-to-the-basement and hybrid fibre-coaxial) into the SAU. The SAU does not currently reflect these technologies.
