Based in the seaside town of Queenscliff, Victoria Australia, Mary learnt to scuba dive in 1983.  Since then she has logged over 2000 dives.  Her passion for underwater photography has led her to most locations along the south-east and east coastlines of Australia, as well as Bali, New Zealand, the Caribbean and many Pacific islands.

Her dedication to her work has seen her published in many publications including Sportdiving Magazine, Dive Log Australia, Scuba Diver, Underwater Geographic, Dive Log New Zealand, Ocean Action, numerous conservation publications and calendars, Melbourne’s two largest newspapers and the prestigious American title: National Geographic. Readers saw her shot of an uninvited five metre great white shark approach within touching distance to inspect her for lunch, but then decide it wasn’t hungry.  There was no shark cage and there was no waiting around for a second shot.

In 1995 Mary received Best Of Show at the Kodak Oceans New Zealand Photographic Competition with a single entry.  Then in 1998 Mary accepted an invitation to display her work in an exhibition entitled “Unique South” at the Treasury Gallery Melbourne.  In November 2011 for three months, Mary's work highlighting Port Phillip Bay's marine environment was part of a photographic exhibition at the National Wool Museum in Geelong.

As a Victorian marine wildlife photographer, Mary feels priviledged living on the shores of Port Phillip Bay.  In her opinion Australia's best diving due to its diverse and dynamic habitats.
