This is the first fossil I have in my collection from Australia. It's a brachiopod called Epacrosina fulva and has some cool bryozoan epibonts on the surface.
Here are a couple of closeups of the Bryozoans. You can also see a barnacle spat or two on there. Based on how they grew on the brachiopod, the growths look post mortem as the Bryozoans seems to grow over the lips of the two shells on the anterior.
The specimen above came from the Pliocene aged Whalers Bluff formation near Dartmoor, Australia.
