Prior to the strike, Don McLeod apparently wrote voluminous letters to the writer and Australian Communist Party member Katherine Susannah Prichard who lived in Perth (though these do not seem to have survived) as well as long letters to the anthropologist A.P. Elkin on the other side of the continent (which have survived).
