New data on phone and internet complaints released

The Telecommunications Industry Ombudsman (TIO) has released its latest data on phone and internet complaints. A telecommunications expert is available to comment.

Associate Professor Mark Gregory, School of Engineering

“Overall, the number of complaints to the Telecommunications Industry Ombudsman (TIO) continue to decrease year-on-year.

“However, it is no surprise that there was an increase in telephone and Internet complaints associated with the recent Optus outage. The number of complaints between October and December 2023 increased by 13.4 percent compared to the previous quarter.

“The big telcos continue to account for most of the complaints during the quarter.

“For many consumers, the telecommunications issues are now lack of performance, and this metric is not adequately covered by the TIO scheme.

“The Government’s audit of mobile performance in regional and remote Australia is due to commence this year, and possibly will provide motivation for an expansion of the TIO’s role to include more performance-related issues.”

Mark Gregory actively participates in public debate covering telecommunications, digital security and the Internet. He currently works as an Associate Professor in the School of Engineering at RMIT University.
