In Present Tense: Anna Schwartz Gallery and Thirty-Five Years of Contemporary Australian Art by Doug Hall we published on page 163 certain matters about Mark Schaller. We now accept that those matters contain several false claims against Mr Schaller. In particular, we acknowledge that Mr Schaller is not homophobic, did not use the language credited to him towards Ashley Crawford and did not throw beer cans at Mr Crawford. We unreservedly apologise to Mr Schaller and his family for the damage caused to his reputation by that passage in the book.
