Neil Balnaves AO, a long term Mosman resident, made a pledge in 2010 to donate a million dollars worth of paintings from his personal art collection to the Mosman Art Gallery and municipality. The Balnaves Gift is unquestionably the most important donation ever to be received by Mosman Council featuring sixteen Australian Impressionist and early twentieth century artworks significant to the Mosman including key works by Arthur Streeton, Conrad Martens, Will Ashton, Henry Fullwood, Elioth Gruner, George Halstead, James Ranalph Jackson, Matthew Charles Meere, Adelaide Elizabeth Perry, Sydney Long, Ethel Carrick Fox and Margaret Preston.
