A WA woman who died after going into cardiac arrest while in jail for unpaid fines was only afforded the opportunity for "lifesaving CPR" because of her cellmate's "heroic" actions, after the prison's nurse rushed to her cell with an empty oxygen tank, the state's coroner has found.
Cally Graham died at the age of 31 in February 2017, six days after she arrived at the then-privately operated Melaleuca Prison in the southern Perth suburb of Canning Vale.
