Father of three David Hogbin from NSW was identified on Tuesday as the victim of a 4.9m crocodile attack near Cooktown in far north Queensland.
Queensland Police confirmed human remains were found inside a crocodile after it was humanely killed on Monday.
Rangers had targeted the crocodile with a distinctive scar near its snout as an extensive three-day search for Dr Hogbin.
He had been fishing with his wife and three boys at Annan River Bridge on Saturday afternoon when he fell into the water, failing to resurface.
The reptile was located in a creek 4km upstream from the attack.
"Dave was having an incredible time on a 4WD and camping trip in far north Queensland with his wife, Jane, his three beautiful boys and Jane's family," friend Alex Ward wrote on GoFundMe.
"While walking along an established path on a riverbank, it is believed a portion of the bank gave way, causing Dave to fall into the river with a known crocodile.
"One small consolation is that none of Dave's children witnessed this event."
The GoFundMe has raised more than $10,000 as of Tuesday afternoon.
Police are working with wildlife officers as investigations continue amid reports crocodiles have been fed by humans at the spot.
A report will be prepared for the coroner.
