[5] A formative experience for Bull was being able to work with many of the artists who visited the Western Front, including Al Neil, Margaret Dragu, General Idea, Marshalore, Clive Robertson and Robert Filliou.
In 1980 Craig and Bull embarked on an extended trip around the world, meeting artists, learning and performing in Japan, Indonesia, India, Cameroon, France, Austria and Croatia (Yugoslavia).
Along similar lines, a series of conferences organized by Littoral (Lancashire UK) enabled artists to work directly with sheep farmers and others living in agricultural communities.
In 1998, along with Zheng Shengtian, Bull organized the Jiangnan Project, a dozen exhibitions in Vancouver devoted to telling the story of modern and contemporary art in the Shanghai region of China.
[7] As director of Centre A until 2010, Bull worked with curators Steven Tong, Sadira Rodrigues, Alice Ming Wai Jim and Makiko Hara to produce over 100 exhibition projects by Canadian and international artists.
In 2015, a survey exhibition, "Hank Bull: Connexion" was organized by Confederation Centre Art Gallery, Charlottetown, curated by Joni Low and Pan Wendt.
Based on Bull's personal art collection and his extensive archive of props, costumes, videos, books and correspondence, the exhibition travelled to five public galleries across Canada.
