Bindi Irwin realizes that everyone handles loss in their own way.

The "Dancing With the Stars" champion was at the AACTA Awards in Australia on Wednesday, where she spoke to media about her family's complicated relationship with Steve Irwin's father, Bob, who Bindi says became reclusive after his son's tragic death in 2006.

"Everyone deals with grief differently," she claimed of her estranged grandfather. 'When my dad passed away he chose to distance himself from everything that dad loved the most."

"At the moment we’re really just respecting his wishes because he hasn’t had anything to do with us for a long time and he decided his own path," she added to her claim. "There was one year where we sent birthday presents to him and he opened them up and he sent them back."

Meanwhile, the rest of Bindi's family appears closer than ever. The 17-year-old recently returned to Australia to celebrate her brother Robert's 12th birthday, before reuniting with her dancing partner, Derek Hough, this week. ET caught up with the two on Tuesday while they reconnected.

"I miss you the most," Bindi told Derek of her time on "DWTS." "It was a long time and then all of a sudden you get home and you're like, 'My big brother isn't here anymore.' It was really quite strange for sure."

"Dad forever lives with me and I think it's the same for myself and my whole family," she said. "No matter where I go in life, I think his strength and determination is what keeps me going."
