During research at the National Archives of Australia in Canberra, three issues of the Caritas Croata bulletin published in Sydney in 1951, 1952 and 1953 were found. The bulletin is not mentioned in other sources, and was the subject of an investigation by the Australian authorities as a foreign language publication. In addition to the surviving copies, the National Archives of Australia also held documents related to the investigation (NAA: A6122, 306).
The three colors are available in the Caritas Croata virtual collection in the Croatian Emigrant Press repository.
