Duncan Moodie came to South Australia from South Africa in the late 1860s, living in Port Adelaide. Known as a 'character', he was dismissed from his work for the customs at the port, and began writing 'The Chronicles of the Customs'. This proved successful, and he started the weekly satirical paper The Portonian, with cartoons by J. Eden Saville, in 1871. Appearing soon after the demise of Eustace Reveley Mitford's journal Pasquin (1867-1870), The Portonian was successful for a while, but did not survive past 1879.
While in South Australia Moodie published a book of poems and The History of the Battles and Adventures of the British, the Boers and the Zulus, in Southern Africa from 1495 to 1879...also A Short Sketch of South Australia (1879). He was active in encouraging enlistment from Australia to boost the British forces in South Africa during the Transvaal War. He later published another volume of poetry, Southern Songs, in South Africa in the 1880s. Moodie left Australia for South Africa some time after 1882. He died at sea en route to England in about 1891.
