There were three wallabies, including one that looked like a juvenile. They were eating grass very on the shore, close to Lake Tarourga's blocked mouth. In checking my photos later I could see that two of the individuals, including the possible juvenile, had some growths around their eyes, with the juvenile possible having a milky white eye. (I have zoomed in on the faces of the two individuals that I noticed had the growths.) The probable adult seemed to have an advanced condition with the bottom eyelid possibly very exposed. I didn't seem them scratching at their eyes or appearing irritated by them, although they did seem to keep their eyes half-closed at times but that could have been the sun. I thought the group was calm because they were not concerned by my presence and kept eating, even though I was only about five metres away, however, I am wondering if the eye problem indicated an illness that made them lethargic. They later hopped away, casually but they seemed confident enough to move, although the juvenile took a while to follow the older animals.
