Marshall was Head of printmaking at Sydney College of the Arts from 1977 to 1989 before moving to Victoria where she taught at RMIT, Monash, Ballarat and La Trobe Universities. Since 1994 she has maintained a productive relationship with the Printmaking department at Tasmanian School of Art, Hobart, working and exhibiting with Milan Milojevic and Barbie Kjar. From her annual pilgrimages to Tasmania she became increasingly pre-occupied with the sea and its tempestuous nature. She has produced significant bodies of work based on the carved figureheads in Maritime Museums and their earlier prototypes from Antiquity.A studio residency at the British School Rome led to a study of Ancient Roman floor mosaics, fountains and sculpture.
Since 1975 she has had 35 solo exhibitions and participated in over 80 group shows throughout Australia in Europe and Japan. She was one of the inaugural artists at the Power Institute, Cite International des Arts in Paris in 1974 and also the inaugural winner of the Silk Cut Award for linocut in 1994 and the ANL Maritime Art Award, in 2005. In 2008, she was the recipient of an Australia Council grant to the British School in Rome.
Her practice as a printmaker has been governed by the conventions of mark making, and she is recognised nationally and internationally for her distinctive cutting and engraving methods and style. Her painting is characterized by a strong chiaroscuro, repetition of mark making and shifting patterns of light and shadow. In her imagery ,she continues to explore the sea, representations of water, storms, shipwrecks, fabulous sea monsters and fountains.
Jennifer Marshall’s paintings, prints and artist’s books are highly regarded. She has exhibited throughout Australia and in Japan, France, Italy, Poland and the UK. She is represented in major State and Regional Art collections as well as numerous private and public collections and her work is included in the archive of the Glasgow Print Workshop .
