In 1879 Sladen migrated to
Australia, his uncle, Sir
Charles Sladen, being the 6th
premier of Victoria. Although he studied law at the University of Melbourne (LL.B. 1882), intending to eventually enter politics, his uncle was reaching the end of his career and losing influence, and he had no real interest in law. In 1883, he became the first
professor of history in the new
University of Sydney. Because of his lecturing in the "Oxford fashion" and the tenuous status of his subject in the curriculum, he "made little impact"; in 1884 he and his wife left Australia. Sladen considered himself first and foremost an anthologist; in 1940, he referred to himself as "an editor of anthologies" in the foreword of a book by his friend Ella Grainger. When Ella Grainger, by then married to
Percy Grainger, returned to England for a visit, Sladen was "rejoiced to find that she had brought with her a collection of poems ready for publication". ==Personal life==
