Telstra is progressively losing ground to its competitors on the NBN network in regional areas, according to data released by the Australian Competition and Consumer Commission.

The ACCC’s fifth quarterly NBN Wholesale Market Indicators Report indicates that NBN Co was supplying a total of 2.07 million broadband wholesale access services at March 31, an increase of 365,853 from the previous quarter.

Almost 1.2 million wholesale access services were in regional areas, compared to 733,880 in areas designated “metro” and “outer metro”.

“The NBN rollout to date has largely been in regional areas. Competitors to Telstra are supplying 46pc of services in the regions, compared with traditional market shares for broadband services where Telstra often had well over 60pc market share,” said ACCC chairman Rod Sims.

Sims also said that the 25/5 Mbps NBN speed tier remained the most popular, making up 55pc of the total services acquired.
