Spouse of the governor-general of Australia

The spouse of the governor-general of Australia (or vice-regal spouse) generally assists the governor-general in welcoming ambassadors and foreign dignitaries and their spouses, and in performing their other official duties. The governor-general's spouse traditionally participates in celebratory occasions and state visits and trips, attends social and state functions and major events, often to accompany the governor-general, and, as a patron of various voluntary associations in their own right, works to promote the activities of those associations.
