In September 2002 O'Shea received an honorary Doctor of Science degree from the University of Wolverhampton, for "services to herpetology".

Originally from Wolverhampton, Mark O'Shea moved to Shropshire in 2001. Since 1980, O'Shea has conducted herpetological fieldwork in over 30 countries on six continents but he has special interest in the Australo-Papuan region. He has worked in Papua New Guinea since 1986 when he first visited the country as a member of the scientific directing staff of Operation Raleigh. He continued fieldwork in the country as a member of the Oxford University Nuffield Department of Clinical Medicine snakebite research team throughout the 1990s, and now researches there under the auspices of a fellowship from the Australian Venom Research Unit (AVRU), based in the Department of Pharmacology at the University of Melbourne. In 2006 O'Shea designed a set of six postage stamps called "The Dangerous Snakes of Papua New Guinea", for Post PNG. The launch of these stamps coincided with the snakebite workshops and fieldwork O'Shea and his colleagues from AVRU were conducting in that country.

O'Shea is a Fellow of the Royal Geographical Society and The Explorers Club of New York. In November 2000 he received the Millennium Award for Services to Exploration (Zoology) from the British Chapter of The Explorers Club. The other recipients were Brian Jones (Aerospace), F.

O'Shea's Big Adventure, or OBA, known as O'Shea's Dangerous Reptiles on Channel 4 in the UK, chronicles his many field excursions to find reptiles around the world. The programs were divided into four series, The Americas, Australasia & Pacific, South & Southeast Asia and Africa & South America. The first two series each contained 13 half-hour films, the latter two each comprised four one-hour films. They were filmed between 1999 and 2003 and have been aired worldwide.

In 1997 and 1998, respectively, O'Shea made two films: Giant Snake in Venezuela and Black Mamba in South Africa.
