Twelve years after Murray's induced birth, his mother miscarried another child. She died after the doctor failed to call an ambulance. Literary critic Lawrence Bourke writes that "Murray, linking his birth to her death, traces his poetic vocation from these traumatic events, seeing in them the relegation of the rural poor by urban élites. Dispossession, relegation, and independence become major preoccupations of his poetry". Beyond this, though, his poetry is generally seen to have a nationalistic bent. The Oxford Companion to Australian Literature writes that:
The continuing themes of much of his poetry are those inherent in that traditional nationalistic identity – respect, even reverence, for the pioneers; the importance of the land and its shaping influence on the Australian character, down-to-earth, laconic ... and based on such Bush-bred qualities as egalitarianism, practicality, straight-forwardness and independence; special respect for that Australian character in action in wartime ... and a brook-no-argument preference for the rural life over the sterile and corrupting urban environment.[7]
Of his literary journalism, Bourke writes that "In a lively, frequently polemic prose style he promotes republicanism, patronage, Gaelic bardic poetry, warrior virtu, mysticism, and Aboriginal models, and attacks modernism and feminism."
