Shark attacks, deep sea fishing and six hour swims. With the Australians dominating the pool in Tokyo, this week The Betoota Advocate interviews two people who have travelled the world swimming a bit deeper below the surface. Free diver, Julia Wheeler and Navy rescue diver Paul De Gelder are the hosts of Dirt Down Under. It’s a podcast that focuses on the intensity of the ocean, and what’s being done to save it.
