In 1943 he started work as an assistant research officer with the CSIR Division of Fisheries at Cronulla,
New South Wales, Munro continued to work at CSIRO as a research scientist until his retirement in 1984, but continued to work as an Honorary Research Fellow at CSIRO until shortly before his death. Earlier, Munro had worked to document the poorly known fish fauna off northern Australian and
New Guinea, and from 1948-1950 he participated in fisheries surveys in the region to document the fish fauna. Munro published almost 100 papers related to ichthyology and fisheries research, including the significant monographic works "The Marine and Freshwater Fishes of Ceylon" (1955) and "The Fishes of New Guinea" (1967), the first thorough treatments of the fishes from these regions. ==See also==
