There maybe an element of truth is what he says, although his motives are opposed to ours.

There was a recent TV doco about elephants being trans-located into Pilensberg National park RSA and a lot of suspicious rhino deaths began to occur. National parks rangers found that the lack of mature bulls had unbalanced the social order and it was adolescent male elephants doing the killing.

There is no doubt that the croc. pop. in NT and Qld has grown. An holistic approach to entire croc population management would work allowing trophys to be taken.

I don't mind Bob Irwin. He was working with crocs for financial gain long before his son gained popularity.
