He reportedly died overnight yesterday on board a flight home from Belgium where he had received an honorary doctorate from Belgian Francophone Universite Catholique de Louvain (UCL).
Talk Radio 702 quoted his ex-wife Alta Brink confirming he had died yesterday evening.
Winner of several book awards and nominated three times for a Nobel prize, Brink was a literature professor at the University of Cape Town.
Among the most widely-known of his works was his 1979 novel "A Dry White Season" which was made into a film starring Marlon Brando.
Brink was a key member of the Die Sestigers literary movement of the 1960s that campaigned against the apartheid government using the Afrikaans language.
