100 years old and not hurt anyone?

You've got to respect that!

Foxy,

As far as is known; a local policeman said it was probably too old and slow to catch humans.

A mate of mine had a 4 m croc ram his dinghy & snap at the outboard motor for quarter of an hour. He didn't venture out in the dinghy for 4 years until the croc was captured.
Last year we visited several creeks along the coast north of Cooktown & we saw an average of one 4m croc every kilometre.
There aren't enough crocodile farms to accommodate big crocs were they to be captured.
One can only guess how many people got taken before it was realised that big estuarine crocs venture many kilometres upstream in freshwater creeks & before there was cattle & other introduced animals for the crocs to feed on.

I saw a preview of "Ä Current Affair" coming up.
It's going to be about a womman who has three
crocs as pets. Is that even possible?

Foxy,

Depends on the size and the species, actually, I like crocks, a crocodile steak is good eating.
