Biography

Felix Albert Fernau (1873 - 1916) was born in Belgium, of Belgian and English family, and studied at University College, London. He seems to have travelled a great deal, and worked in various occupations in Morocco and Argentina before taking up teaching English in South America, France and Belgium before returning to England to take up a call to ministry. He trained at St. Aidan's College, Birkenhead in Cheshire, and was ordained in England by the Bishop of North Queensland.
After assisting with care of passengers during an on-board epidemic as a chaplain on an immigrant ship to Australia, he served in Charters Towers and then took up missionary work in New Guinea, leaving there in poor health before taking up a curacy at St. John's, Launceston from 1902 to 1906. 
During his time at St. John's, there was an outbreak of smallpox. At Fernau's later farewell from St. John's, Canon Beresford said that he "...was conscious that their sympathy with Mr Fernau was largely the outcome of his heroic conduct during the outbreak of small-pox two years ago. It spoke well for the faith which they professed that the Rev. Father O'Mahoney and Rev. Mr Fernau and Dr. Barnard, together with a large band of nurses, showed that they were willing to attend the sick and minister to the dying." This was in accord with his earlier ministry to the sick during the voyage to Australia.
After leaving St. John's, he was appointed assistant curate at All Saints Hobart, an appointment which may have been short-lived, because he went on to serve as superintendent of a leprosy quarantine hospital on Peel Island in Moreton Bay (off Brisbane).
In 1912, he returned to church ministry, first as a mission chaplain, then as rector of Childers until 1915 when he requested to move to the Bush Brotherhood. This took him to Charleville, but the following year, he died as a result of burns that resulted from him re-entering the burning rectory twice. It was not circulated at the time why he had re-entered the burning building, but according to the linked Anglican Focus article, notes on a photo found in the Bush Brothers records said he was trying to rescue his dog.
