Moore met and married theatre impresario J. C. Williamson in the U.S. and became popular as an actress in their production of Struck Oil, which premiered in 1873 and was revived many times.

She continued a busy acting career in Australia and on tour worldwide, ending her marriage with Williamson and later marrying actor Harry R. Roberts.

Sullivan was born in San Francisco, California, in 1851 to Irish parents; her father, who died when she was eight years old,[2] was from Dublin, and her mother was from Galway.

[5] In 1876 Struck Oil played for 100 nights at the Adelphi Theatre in London and was followed for a similar period by Arrah-na-Pogue, with Williamson as Shaun and his wife as Arrah.

[7] She was versatile, and after her husband had become a member of the firm of Williamson Garner and Musgrove and had practically given up acting, she appeared in sensational drama.

Back in Australia she played a starring season between 1908 and 1912, occasionally reviving Struck Oil with her husband as John Stofel and making a film of the same name, which was released in October 1919.

[19] That year, she celebrated the fiftieth anniversary of her first appearance in Australia,[20] and in 1925 retired to California to live with her sister, Mrs Comstock.

[citation needed] Moore died at San Francisco after having an operation to remove her leg, following a cable car accident on March 15, 1926, aged 74.
