Mt Duneed is a low hill to the south of Geelong – you can see it as you head to the beaches at Torquay. It has a nest of towers on top because it's the highest point in the vicinity. Such an innocuous-looking hill, but actually a volcano that had quite an impact on the countryside.
Once there was a large, shallow embayment on the coast to the east and south of Mt Duneed, and lava from the volcano flowed into and filled the bay. Thompsons Creek now flows along the southern edge of the basalt and out to sea at Breamlea, and the Barwon River and Lake Connewarre are to the north. Just to the north of Breamlea the basalt meets the sea, one of the few places in Victoria that that happens, at a place called, imaginatively, Black Rocks. Surfers like the waves nearby, off the sandy beaches at Bancoora and 13th Beach, and Hooded Plovers attempt to nest on the sand there every year with little success because of human and animal traffic, but at Black Rocks the waves crash in onto the basalt.
