He was 44. Prior to giving birth to Grace in March on her 1-year wedding anniversary with husband Chandler Powell, Bindi told Entertainment Tonight that her father likely would have been a loving grandfather. "He would've been a good, good grandpa. Yeah, he really would've been," said the Crikey! It's the Irwins star in February. "I don't think we would've ever seen our daughter. He would've just whisked her away into the zoo and it would've been perfect." As she noted in Saturday's tribute, Bindi is giving her daughter a glimpse at who her grandfather was through family photos and videos.

"It's really special." Later that month, Bindi said her daughter's nickname, Baby Wildlife Warrior, was a tribute to her father in an interview with The Bump. "My dad was the first person to create the term 'Wildlife Warrior.' Being a Wildlife Warrior means to stand up and speak for those who cannot speak for themselves," the Animal Planet star explained.
