OMG Starfish heaven. That's a beauty. I don't recall seeing startfish like these on Australia's east coast, although the warm current most likely has something to do with that. They might be here, but I haven't seen them. I wonder if Mark and Leuba have down Melbourne-way. Bass Straight is much colder, and probably more like Pacific northwest waters.
