Australian Competition and Consumer Commission Rod Sims told The Australian that this was more than a health check and the sector was in a state of flux and uncertainty.
NBN prices have been a constant source of complaint and there is often a blame game indulged in by the NBN Co and retail service providers when there are problems with a connection.
Sims said that there were other things, such as the impending entry of 5G, the Internet of Things and its spectrum needs and whether Australia had the right investment for the anticipated growth in data use.
He said that the moves by Vodafone in the NBN market and TPG Telecom's entry into the mobile market were positives.
But, he said, there was a need to examine whether the ACCC's existing regulatory mechanisms were enough to manage a changing industry.
Sims said that there was a limit to the extent that the ACCC could make the NBN Co disclose wholesale speed information.
“NBN Co’s data is all about measuring speed at the access level. It doesn’t measure what the box the RSP is putting on the NBN provides, it doesn’t measure the contention from the ISP," he said.
“The data is important to us but there’s no point putting that data out to the public,” he said.
With regard to the legal dispute between the ACCC and Vodafone over mobile roaming — the telco has questioned the process followed to determine whether to declare mobile roaming — Sims said while there was "some validity in Vodafone saying that there’s a vicious cycle in play that entrenches Telstra’s monopoly … but it doesn't determine the debate".
