Guerilla Bay

Guerilla Bay

Guerilla Bay

From the ancient pacific

Guerilla Bay is one of the most hidden, sheltered and picturesque bays in Eurobodalla, and has been formed in some of the oldest rocks – dating back 510 million years – along Eurobodalla’s coastline.

These exciting rock formations and features are layers of chert and slate, and were initially laid down in the ancient Pacific Ocean, before becoming part of the Gondwana continent possibly during an interval of subduction.

A subduction zone is an area where tectonic plates move together, or converge, with one plate overlapping and overriding the other; they can sink to great depths in the Earth’s mantle at a 25 to 90 degree angle. Through the high temperatures and pressures associated with this process, seabed sediment is converted to rock. Although plate movement only occurs at a rate of centimetres per year (comparable to fingernail and toenail growth rates), an active zone such as in Japan or New Zealand, can cause tsunamis and earthquakes.  Through plate movement sediments and rocks can be carried long distances to become part of land masses.

Squeezed, bent and broken after they formed, possibly as a result of compressive movement within the ancient subduction zone, these Guerilla Bay rocks now consist of a mix of fragments called tectonic melange. Also contained in these chert rocks are tooth-like microfossils (less than 1mm) from the gut of extinct eel-like animals, however a microscope is needed to see these minute fossils.

How to get there: Guerilla Bay is 13km south of Batemans Bay and accessible from George Bass Drive. Drive south along the Princes Highway to Mogo, turn left into Tomakin Road, and left into George Bass Drive. Or take the scenic coast route from Batemans Bay along Beach Road to George Bass Drive via Batehaven, Lilli Pilli, Malua Bay and Rosedale. From George Bass Drive, turn east into Burri Point Rd which takes you to Guerilla Bay. There is a small car park, a few picnic tables but no other amenities.

Things to do: Guerilla Bay is suitable for swimming, snorkelling and kayaking in calm seas and is the starting point for the 1.5km Banksia Walk to Burrewarra Point. The kids will love the rock pools and climbing the rocks.
