In 1959 he was a signatory to the
 a statement protesting the dominance of
abstract expressionism. The manifesto's adherents have been dubbed the Antipodeans Group. His work is associated with dreamlike images tinged with mystery and foreboding. In 1960 he and his family lived in London after Blackman won a
Helena Rubenstein travelling scholarship, settling in Sydney upon his return five and a half years later.
 In 1970 he moved to Paris, when awarded the atelier studio in the Cité des Artes. He lived there for a year at the same time as John Coburn, and subsequently returned often, as Paris was an eternal source of inspiration.
After 27 years of marriage, Barbara Patterson Blackman and Charles Blackman divorced in 1978, largely because of his alcoholism. He married the young artist Genevieve de Couvreur, a 19-year-old friend of his children.
 She divorced him after 8 years, as his alcoholism grew deeper; and in 1989 he married a third wife, Victoria Bower, whom he also later divorced. He has six children, Auguste, Christabel, Barnaby,
Beatrice, Felix and Axiom, most of them artists and musicians in their own right.
