Australian Story host Caroline Jones AO has announced she will step aside from her role after more than 50 years at the ABC.

Jones, who first joined the ABC in 1963, has contributed to and presented Australian Story since its launch in May 1996.

"This is not an easy decision for me," she said.

"The ABC is in my DNA. So is Australian Story, and that will not change."

She said it had been a "joy and privilege" to work on the program "and with the generous Australians who tell us their stories, giving profound insights into the complexity of our human condition in a speedily evolving world".

"I'm far too busy to retire, but now there are some other loyalties claiming my attention, and I move on to the next phase of my life with gratitude. There's always another adventure ahead."

Jones was the first female reporter on Australia's first national nightly current affairs program, This Day Tonight. She was also the first woman to anchor Four Corners.

"Caroline is simply a legend of Australian journalism, a trailblazer, an inspiration and a role model for so many women in the media," Director of News Gaven Morris said.

"We will miss her deeply at the ABC."

Jones has received numerous awards for her work, including a Logie Award and Walkley Award.

In 1998, she was made an Officer of the Order of Australia and in 1997 she was voted one of Australia's National Living Treasures.

Jones will not be replaced as presenter when Australian Story returns to air on February 6, 2017.
