Craig came from Britain to the goldfields in Australia in 1851 'after reading Major Mitchell's interesting work on the climate and resources of Australia Felix' (My Adventures p. 1). By the time of the publication of his book, he lived in Invercargill, New Zealand.
According to information supplied to AustLit by his grandson Stephen Lipple,
Will Craig under that name, as Wil Kraig or his many pseudonyms contributed 2068 letters articles, editorials and occasional poems and advertisements to at least 29 newspapers and to the three magazines he briefly published. He was employed by nine newspapers, though his status with The Labor Call in Melbourne is unclear and no contributions from his pen appeared in The Truth (Melbourne) or The New Zealand Standard. It was his three Labour newspaper employers plus a fourth, The Labor Call, that rank as his most prolific publishers, printing 1818 items (90 percent) of Craig’s material. Of the four, the order was The Daily Post (1149), The Maoriland Worker (340), The Labor Call (270) and The Daily Herald (59). The much higher number in The Daily Post reflected the fact that it was a daily paper whereas the others printed weekly editions. The monthly Steads Review, then liberal in tone also published 72 of Will’s freelance articles. Most of these were attributed to 'Walter Greig'. The remainder of Will’s material mostly appeared in newspapers of Labour persuasion.
In 1927, he sent a copy of his book No More Poverty to Mary Gilmore, inscribed 'To Mary Gilmore, co-worker in The Cause, from Will Craig Melbourne, 29th November 1927': the inscribed copy is held in the Mitchell Library in Sydney.
