HONG KONG (AP) -- The youngest Irwin is following in the TV hosting footsteps of late "Crocodile Hunter" Steve Irwin and big sister, Bindi.

Nine-year-old Robert Irwin will co-host "Wild But True" on Discovery Kids Asia, exploring parallels between nature and science.

He calls it a "really, really cool concept" for a television show. "... it's about how science has gotten ideas and built from inventions from the natural world," he said.

The siblings appeared regularly on their father's show before he died from a sting ray injury in 2006 while shooting a documentary.

Bindi Irwin also has television shows of her own and a few film credits. She says Robert doesn't need tips about being in front of the camera, but if there was one piece of advice that she could give him, it would be something from their father.

"I think that the greatest tip that dad gave myself when we started filming is that he said, 'When you talk to the camera, just talk to it like you're talking to a person, because that's what you're doing, you're speaking to people in their living rooms,'" she explains.

Robert says although he was just 3 when his father died, he has vivid memories.

"He was really, really passionate in every single thing that he did. I think it's really important to carry on for what he did, so I'm really glad that that's what we're doing," he says.

"I think we're really lucky too because so much of our lives together were filmed," adds his mother, Terri. "We've got that family opportunity of always filming together, so we can look back on good times anytime we want."

"Wild But True" is set to premiere across Asia in the third quarter of 2014.
