Nearly 60% of the 5.2 million Australian households connected to the NBN at the end of March are on plans that offer 50Mbps or higher download speeds, the Australian Competition and Consumer Commission says in its quarterly Wholesale Market Indicators Report.

A day before it was scheduled to announce its decision on the proposed merger between TPG Telecom and Vodafone Hutchison Australia, the Australian Competition and Consumer Commission has been forced to announce it is opposed o the merger.

Most NBN users experience less than one outage of 30 seconds or more a day, but Optus customers on average had to suffer through more than 1.5 outages each day, according to the Australian Competition and Consumer Commission's fifth report on NBN speeds.
