Ms Walters will fly to Australia tomorrow for a sit down interview with Steve Irwin's wife and eight-year-old daughter for a one-hour special to be aired on the network next week.
"I'm going to go to Brisbane, Australia, to do an interview with Terri Irwin and with their little girl, Bindi," Walters announced on her morning talk show The View.
The interview is a worldwide coup following the freak September 4 stingray death of Irwin on the Great Barrier Reef.
"His wife has not talked to anyone about this," Ms Walters said.
Ms Walters said topics she will discuss with Terri include what her relationship was like with her husband and how she was informed of his death.
"It's an assignment I'm absolutely thrilled to have."
"I think people want to know more about him … it was a tragic case."
The one-hour special will be aired in the US on September 27 and should reap huge ratings for ABC as Irwin — through his Crocodile Hunter documentaries — was a much-loved TV star in America.
