just remember that Croc's were hunted ruthlessly, in Northern Oz, right up till the late 60's, when they made it illegal.
Now the numbers have skyrocketed, and the young males ( the big ones ) are being chased out by even biggeer ones.
I am not sure just how far South they have come. but it is a long way.
They are slowly making their way South, towards Brisbane.
