AustLit

In December 1950, financed by proceeds earned from several months of farm labouring, Muirden published the first issue of the literary magazine, the Austrovert. Dissastified with what he believed was the lack of attention given to Australian literature by 'academics and litterateurs', Muirden hoped that the Austrovert would be a 'half way mark' between the daily press and the academy. The Austrovert appeared irregularly, but when Muirden moved to Darwin in 1953, he was unable to continue and the magazine ceased production.

Muirden subsequently pursued a career in journalism, writing for newspapers in Australia and the United Kingdom. Returning to Adelaide, Muirden became a long-serving press secretary to the Labor party in South Australia. He continued to write and review books for newspapers and magazines and edited a number of publications, including the Australian Humanist and the Labor Herald. He also published a number of books, the most significant being The Puzzled Patriots: The Story of the Australia First Movement (1968).

Muirden was elected secretary of the Australian Journalists' Association in 1989, but resigned shortly before his death from cancer in December 1991.
