The youngest Irwin is following in the TV hosting footsteps of the 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.
The siblings appeared regularly on their father's show before he died from a sting ray injury in 2006 while shooting a documentary.
Robert said his show is about how science has got "ideas and built from inventions from the natural world".
Bindi said that if there was one piece of advice that she could give her brother, 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 said.
Robert added that although he was just three 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 said.
"I think we're really lucky too because so much of our lives together were filmed," added 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.
