BRAG acquisitions are received in a number of ways; via the Cultural Gifts Program, by bequest, donations and purchase. In 2004, BRAG received a major bequest from the late Gwen Frolich consisting of 75 works valued at $1.5 million dollars. This remarkable collection, put together when Gwen worked at the Rudy Komon Gallery in Sydney during the 1960s, 70s and early 80s, features work by 30 Australian artists including David Aspden, George Baldessin, Charles Blackman, Leonard French and Fred Williams.
