Writer David Walker grew up in Melbourne, but has for many years lived in Canberra where he has been employed in various positions with the Commonwealth Public Service, while also working as a research physicist, a designer and developer of computer systems, and lecturer (in computing) at the University of Canberra.
Walker has been contributing short fiction, poetry and cartoons for various publications since the mid-1960s, including anthologies such as Under Twenty-Five (1966), The View from the Edge (1977), Singularities (1990), Off the Edge (1995) and Elsewhere (2003). He has also been published in the Canberra Times and Antipodean SF. Walker says of his own literary work: 'Most of my writing is satirical and often doesn't fit comfortably into the standard genres. Some can be labelled speculative fiction (because it is futuristic or set on other planets) but is sometimes accused of not being that, while others are more "finding out" stories, more akin to mysteries (though usually lacking dead bodies). I also draw cartoons.'
In addition to his fiction and poetry, Walker has published text books for computing studies.
