Thanks to Marcus Leach for the initial sighting of what is assumed to be a Flatworm. It was 25mm long as seen in the first image. In the fourth image the head end is on the right.
It is great to see this species again. I saw one specimen many years ago in the Victorian Eastern Highlands. It was originally described from the Burnett River area and Cooran in SE Queensland, but possibly has a disjunct distribution. Excellent photos showing the eyes very clearly.
The habitat was a tiled path through a residential garden, with a lawn on one side of the path and shrubs on the other side. The garden is surrounded by other residential properties with no bushland nearby. There are usually quite a few flatworms on the path in the early evening, especially after rain, but this is the first one of these we've seen. Hope this helps. Tim
