Taken during my PADI Open Water course at the Busselton Jetty - Canon IXUS 4 in dive casing. Although there's heaps to see and photograph down there, this was really delightful, me peering into a hollowed out post and this friendly little chap peering back out at me.

Taken by Suzie Lack at Mills Reef, Darwin Harbour. We think this is a Loggerhead Turtle. He was happily munching on barnacles and oysters amongst the artifical reef structure.

Not sure exactly what this is, some form of soft coral (I believe that it stings - not silly enough to test the theory). In the back ground there is a stinging hydroid (almost fern like) these I know sting - photo from GBR off Port Douglas.
