Just six years earlier, Bindi Irwin also lost her grandmother Lyn, who died in a car accident.
And on Thursday, the 19-year-old paid tribute to her late family members on what would have been a shared birthday for the mother-and-son duo.

‘I promise to do my best to make you proud’: Bindi shared another heartfelt post earlier this month after watching never-before-seen footage of her late father Steve Irwin
Earlier this month, Bindi shared another emotional tribute to her dad, after watching never-seen-before footage of the late Crocodile Hunter.
Bindi claimed she’d only seen the clip for the first time the week prior and said: ‘I don’t think I’ll ever be able to describe the amount of emotion in my heart once the video ended.’
The brief video showcased a sit-down interview with Steve, who gushed about his two children and his hopes for them to take over his wildlife conversation work.

When asked on tape if there was anything that would make him want to give away what he was doing, he responded without hesitation: ‘Yes, there is! When my children can take the football that I call wildlife conversation and run it up.’
‘When they’re ready to run up our mission, I will gladly step aside,’ he said, getting visibly teary as he passionately spoke of his young children.
‘And I guarantee you it will be the proudest moment of my life! My job will be done and then, and only then, will I know that I have achieved my ultimate goal – to be able to stand aside and let them run up my mission,’ Steve said with a wavering voice as he appeared to hold back tears.

‘My dad. My superhero. I promise to do my best to make you proud and ensure your legacy lives on forever,’ she vowed.
