ABC presenter Virginia Trioli returns to radio.

Popular ABC television presenter Virginia Trioli is returning to radio after five years as co-host of ABC News Breakfast.

In March, Trioli will begin hosting ABC Radio's flagship current affairs program AM, replacing Tony Eastley.

Eastley, who has presented AM for 10 years, will become a senior presenter at ABC News 24.

A new on-air partner for Trioli's News Breakfast co-host Michael Rowland is yet to be announced.

Trioli, a two-time Walkley Award winner, started her journalism career at The Age. She has also been a columnist for The Bulletin magazine and has hosted the drive shift on 774 ABC in Melbourne and the morning slot on 702 ABC in Sydney.

"I must admit to mixed feelings as I leave News Breakfast enormously proud of our five year-old program, the team and especially my colleague Michael Rowland, and our loyal, growing audience, and I thank them," Trioli said. "Now that my body clock is permanently set to a 3am alarm, the move seems just right."

Eastley, who is the longest-serving presenter of the 47-year-old AM program, previously hosted the 7pm ABC television bulletin in NSW and The World at Noon. He joined the ABC in 1979 after completing a cadetship with The Examiner newspaper in Launceston.

"Hanging up the AM mic is going to be hard after 10 years but I shan't miss those pre-dawn starts," Eastley said. "But new challenges beckon and I really want to be part of the ABC News 24 rolling news coverage."

The changes are among a few announced by the national broadcaster this week.

ABC News 24 presenter Scott Bevan will front a new prime-time program and anchor major news coverage across ABC News 24 and ABC1.

Tim Latham, executive producer of Fran Kelly's breakfast program on Radio National, has been appointed executive producer of Media Watch.

Dr Rebecca Huntley will host the Friday edition of Radio National's drive program, with Waleed Aly continuing to host the Monday to Thursday editions.
