i was working in national park on the mornington peninsula when i came across this, i was driving a tractor at the time a could not work out what it was because it had to tails from a distance, but on closer inspection it was a snake eating a snake. the snake being eaten was about the same length, as when i first saw them it was only in head dead. took about 10 mins to eat it and was to fat to move so i had to get a very very very long stick to help him along.
