[2] Iannotta played alongside Italy's Carolina Morace in Agliana's 1994–95 Scudetto winning team.
In 1996–97 Iannotta joined Cheryl Salisbury and Sunni Hughes at Panasonic Bambina of Japan's L. League.
Two broken legs, sustained seven months apart, derailed Iannotta's progress in Japan and she returned to Italy.
In 1998 she accepted a place on the Australian Institute of Sport Football Program, ahead of the following year's World Cup in the United States.
In July 2023, the Australian Broadcasting Corporation's digital sports journalist Samantha Lewis complained that footage of Australia's first Women's World Cup goal, scored by Iannotta, is not freely available but is "buried on a database at FIFA headquarters" which would cost "an unfathomable amount of money" to officially license.
