Portrait of King O’Malley, c.1885
As a young man, O’Malley gained experience in banking and in insurance and land sales. It was also then that he became interested in politics. Working his way across the country, at the age of 29 years, O’Malley left the United States of America for Australia. He settled in Tasmania, quickly establishing himself as a successful insurance agent. Toward the end of 1892, O’Malley left Tasmania to spend a brief period in Western Australia, primarily in Kalgoorlie, which was at that time experiencing a gold rush. It was there that he laid the foundations for his considerable estate. With his wealth he began developing an extensive property portfolio in metropolitan and country Victoria.
O’Malley later settled in Adelaide where his strong interest in politics led to him gaining a seat in the South Australian Parliament. He soon became widely known, not only for his flamboyant manner, but also for promoting social reform, demanding justice for low-income earners and supporting the rights of women.
