If Blood Should Stain the Wattle is a 1947 Australian novel by Ailsa Craig.
It was described as "A story of domestic conflict in a country setting. Told with quiet, but compelling power in the manner of Daphne du Maurier."
The novel was serialised in the Sydney Morning Herald.
The Argus said "would be better if some of the propaganda were more subtle."
The Weekly Times said Craig's "style is impressive and she writes convincingly about country scenes with which she is familiar."
The Age said "This book makes entertaining reading, although it is written fulsomely, with some characters trite and others unconvincing."
The novel was turned into a radio serial by the ABC in 1949.
