We reached Jenolan caves in late afternoon, and were so awed by our one-hour tour of Chifley Cave that we decided to stay overnight and visit another cave the next day. In the evening, we walked over to Blue Lake, a small, dam-created body of water just outside the main entrance to the cave complex. I had overheard someone say you could see platypus in the lake, and that turned out to be true. I’m told that platypus are ordinarily very shy, but this one must be accustomed to tourists. The evening chorus of birds and insects was delightful, I captured that, knowing that not much of what I was seeing would be visible in the video.
