She soon met John Kennedy, her future husband, who was fifteen years older than her.

Kennedy campaigned on a platform of city beautification, the preservation of Queens Domain as an open space, and pro-business policies. She wrote at the time, "We need to beautify our carparks—eliminate every possible ugliness... Add to the beauty of our streets by stepping up our tree-planting program and general beautification." Doone Kennedy was elected Lord Mayor in 1986, becoming the first woman to hold the office. She championed beautification programs and city development throughout her five consecutive, elected terms as Lord Mayor.

Doone Kennedy consistently won all five of her mayoral elections with approximately 65% of the vote.

She was the longest serving Lord Mayor in Australia at the time of her retirement from office in 1996. Doone Kennedy remained the only woman to serve as Lord Mayor of Hobart until Sue Hickey's election in 2014. In 1994, Kennedy was awarded the Officer of the Order of Australia.
