Thick and VERY tough outer layer (also called a 'test' for sponges?)
Once again multiple species on the jetty pylons.
Middleton Point at low tide. River Murray flood waters have resulted in large number of dead fish, bivalves and other marine invertebrates washing onto the beach. The bivalves and marine invertebrates normally inhabit the littoral sand zone but could not survive the large influx of Murray water into the ocean.

Exceptionally low tide on sand bar near intertidal rocky reef and Posidonia australis beds.
Can you help with an ID @renecampbell?

This sponge extended for about 1 metre along the underside of a rock ledge.
There were other smaller clumps nearby.
About as large as I've seen them,if suggested genus is correct. Not the size of a golfball, more that of a large grapefruit.
Specimen found washed up on Henley Beach. Historically called Aplysilla rosea. Very common sea sponge on jetties and pylons in South Australia. Photo by Rina Aleman.
