Something in the water

It appears the first pair of Freshwater Crayfish we saw a month ago were just the trend setters. Now we are regularly seeing 8+ Crayfish . These guys-girls range in size from about 15 to 40cm. They all just hang out in the creek, but sometimes if they get too close to one another there is a bit of pincher action. It appears that these freshwater crustaceans are in fact mating. Two months ago we noticed the Great Barred Frogs two at a time - if you know what I mean. Occasionally we get a bit close to campers and also hear some sounds we would prefer not to hear. There certainly seems like there is something in the water at Nightcap National Park.
