After a few more years in France, Boz left for Australia in 1951. There, he was eventually hired by Air France to head its local office, and Boz's literary activity abated until his retirement in 1974. Afterwards, he republished some of his old work in photocopy and contributed to Romanian cultural activities in his adopted country. Never a declared opponent of the regime, his work was nonetheless unwelcome in Communist Romania, and had to wait until after the 1989 Revolution to regain critical favor. During the 1990s and until soon before his death, Boz contributed material to a Romanian magazine. In 2000, a short novel of his dealing with the war years saw publication.
