and Dame
Enid Lyons (pictured together in 1955) are among the longest-serving prime ministers' wives, both holding the position for more than seven years. With a few exceptions, the prime minister's spouse has been by default a public figure, and the subject of media and societal interest. A spouse has no official title, but may be unofficially referred to as Australia's "
first lady" or "first bloke". The prime minister's spouse receives no official salary, and they have no official responsibilities, duties, obligations or staff. By convention, the spouse of the prime minister serves as the host of
The Lodge, the primary official residence of the prime minister, and
Kirribilli House, the secondary residence. The incumbent also assists the prime minister in welcoming foreign dignitaries to
Parliament House, on official state visits overseas and at various other locations during ceremonial events. Some earlier spouses stayed mainly at home and took little part in public life. Many were preoccupied with rearing children, most notably Dame
Enid Lyons (1932–39), who had 12 children (one died in infancy). However, most recent prime ministers' spouses have chosen to also be involved in charities or community organisations, working to raise public awareness, funds, and support for a range of causes. They generally assist their partners in political campaigns and participate in official duties that come with the position, such as hosting foreign dignitaries and, in particular, entertaining the spouses of dignitaries; accompanying the prime ministers on national and international trips; attending conferences and functions; and speaking in public, particularly in the prime minister's constituency. They have attended the opening of Parliament; visited
Buckingham Palace, the
White House, or the Japanese Imperial Palace; and been present at royal coronations and conferences. ==Careers and public office==
