One of the Boomerang pilots I've interviewed talks about crocodiles when he was based at Horn Island in the north of Australia - the'd be sunning themselves on the water's edge unaware a fighter was about to pounce. When you hit them with the machine guns they'd jump into the air and land in the water. When hit with a burst of 20mm cannon fire they'd instantly be turned into flying pieces of meat.
For reference here is a shot of a Boomerang to refresh your memory:

Another famous crocodile hunter turned documentary maker died a couple of days ago in a vehicle accident oh his property. Malcolm Douglas was well known and very well liked here.
