Hanging Roots in Olwolgin Cave

  About the dive Olwolgin Cave is located on the Roe Plain, Western Australia, not far from Burnabbie Cave. As I posted previously, the Roe Plains caves are quite different from the white walled, blue water, big tunnels of the better known Nullarbor Plain caves. The first thing you notice is the yellowish tint to the water (but not to the walls) and the narrow, twisting, multilevel nature of the cave. With the water level close to the surface, tree roots from the desert above intrude into areas of the cave. However, the Roe Plains cave also have unique salinity characteristics. Instead of a single halocline with a distinct mixing zone between layers of fresh and salty water, like might [read more…]

Bathtub in Warbla Cave

About the dive Warbla Cave is a scientific reference cave located on the Nullarbor in Western Australia which is closed to general access. With pure white walls and interesting formations, not to mention the colonies of bacteria found in protected areas, it was a dream cave for photography. A scientific permit is required for entry, along with excellent fitness to transport our dive gear through the cavernous dry cave area. Ducking under a low ledge towards the end of this huge space, we negotiated a steep slope of dried bat guano to get to the water. This scientific trip was set up to replicate and measure some of the variables that had been studied in 2000. Our goals included setting [read more…]

Wreck of the George Kermode

About the wreck The George Kermode was a bucket dredge of 1,380 tonnes, known as the Sit William Matthew when she was built in 1914 for the Ceylon Government, Colombo. After being acquired by the Australian Government in 1917 and then the Melbourne Harbour Trust in 1941, she was scuttled on April Fool’s Day 1976, off the southern coast of Phillip Island. She lies upside-down in about 20m of water, coming up off the bottom to nearly 12m in some places. Being so shallow compared to most of the wrecks accessible out of Port Phillip Bay you get plenty of time to explore. The Kermode is broken up in the middle, with big buckets lying out on the sand in [read more…]

Cathedral in Piccaninnie Ponds

About the dive Piccaninnie Ponds is one of my favourite sites for cave photography. As well as the crystal clear water and very white rock, there’s the novel aspect of being able to get natural light in the shot. The main drawback is that, once inside the Cathedral, you don’t have very long to experiment before silt starts to drift down off the roof. Naturally, taking advantage of the opportunities is also dependent on the sun coming out to play. I previously talked about a photo taken in the Chasm of Pics, looking up through the scalloped limestone walls. Swimming forward from here divers move under a limestone ceiling, and enter the Cathedral. Large rocks sit across the path between [read more…]
