During his directorship, the NGA gained government support for improving the building and significant private donations and corporate sponsorship. However, the initial design for the building proved controversial generating a public dispute with the original architect on moral rights grounds. As a result, the project was not delivered during Dr Kennedy's tenure, with a significantly altered design completed some years later. Private funding supported two acquisitions of British art, including David Hockney's "A Bigger Grand Canyon" in 1999, and Lucian Freud's "After Cézanne" in 2001. Kennedy built on the established collections at the museum by acquiring the Holmgren-Spertus collection of Indonesian textiles; the Kenneth Tyler collection of editioned prints, screens, multiples and unique proofs; and the Australian Print Workshop Archive. He was also notable for campaigning for the construction of a new "front" entrance to the Gallery, facing King Edward Terrace, which was completed in 2010 (see reference to the building project above).
