There is a little talk of it here https://www.mackayandwhitsundaylife.com/article/remembering-...
I had seen him get bitten by a bunch of different snakes during his time demonstrating dangerous animals to my school on different occasions, he was always very kind and educational.
I believe he had was also involved in milking snakes and making antivenom, but the specifics evade me.
I believe he went to many different schools educating the small townships of the Australian outback (Imagine more than 20 less than 30) and always had time to answer my stupid questions as a child.
This part of my local culture will be missed.
