Critical reception
The Australian novelist Christina Stead recommended Hay's 1918 novel and noted that Patrick White also admired it:

I have just finished a truly remarkable novel...: The Escape of the Notorious Sir William Heans (and the Mystery of Mr. Daunt)... by author William Hay..., writing about the penal settlement days in Tasmania (one of our worst convict settlements, that of Port Arthur). Given to me by friend-novelist Patrick White: he so greatly admires it that he "keeps buying it and giving it away." This magnificent writer is a most serious deepdyed scholar, student of the epoch and his work is a sort of epic, an Inferno, not the usual horror-story of beatings and killings in prison... an ascent from Avernus. (...) One of his wonders is his extraordinary use of the human face as a stage for conflicting emotions — often all at once!

Tributes
The 3rd issue of 1946 of the Australian literary magazine "Southerly" was devoted to the works of W. G. Hay.
