The registered nurse has crucial preventative, therapeutic, sociocultural, and advocacy roles in promoting quality holistic patient-centred palliative care. This paper examines, describes, and analyses this multifaceted role from an antipodean perspective. We conducted systematic searches using PubMed, Google Scholar, government guidelines, authoritative body regulations, quality control guidelines, and government portals pertaining to palliative care nursing in Australia. This paper relies upon the information garnered from publications, reports, and guidelines resulting from these searches and analyses. The fundamental principles and guiding values of palliative care (and nursing) and the raison d’etre for palliative care as a discipline are underscored and expanded on. Australian Clinical Practice Guidelines (CPGs) pertaining to palliative end-of-life (EOL) nursing care and associated services are discussed. The relevant NMBA nursing standards that RNs need to have to administer opioids/narcotics in palliative care are summarised. The identification of patients who need EOL care, holistic person-centred care planning for them, and consultative multidisciplinary palliative clinical decision making are discussed in the palliative care context. Several components of advance care planning apropos health deterioration and conflicts are discussed. Several aspects of EOL care, especially palliative nursing care, are analysed using research evidence, established nursing and palliative care standards, and the Australian EOL CPGs.
