A handwritten note written by legendary conservationist Steve Irwin has recently been discovered.
In the letter, Steve opens up to his parents about how he is only just beginning to understand the meaning of life, and how to be happy.
"Probably one of the most unfortunate things in a 'Bloke's Life' is that it takes over 30 years to realise how essential you have been to build my character, my ethics and, most importantly, my HAPPINESS," penned Steve.
"At 32, I am finally starting to figure it out. In good times and in bad, you were there.Your strength and endurance to raise me will not go unrewarded. My love for you is my strength!
"For the rest of my life I will reflect on the unbelievably GREAT times we've shared and will continue to share. You're my best friends!"
The touching letter was written only four years before Steve was to be blessed with two children, his beloved Bindi and Robert.
This Sunday marks the 10 year anniversary since Steve was tragically killed by a stingray, when his children were only eight and two years old.
The uncovered letter has now been published in his fathers memoir, The Last Crocodile Hunter: A Father and Son Legacy.
