Corletto started playing netball at aged 10 in home town of Kerang. She made her Commonwealth Bank Trophy debut at the age of 16 for the Melbourne Phoenix, where her style of defence saw her named Netball Australia's best new talent. She was selected in the Australian open squad at the age of 17. In 2005 she captained the Australian U/21 team to a bronze medal at the World Youth Championships, while on the comeback trail from a stress fracture in her foot.
In 2007 Corletto was recruited from the Melbourne Phoenix to cross-town rivals, Melbourne Kestrels. Also that year, she was named in the Australian national team to tour England in a tri-series. However, after injuring her ankle in the first minutes of the season opener, the local derby between Phoenix and Kestrels, she was forced to pull out, with Melbourne Kestrels team-mate Rebecca Bulley called up in her place. But a few months later Corletto went on to make an impressive debut for Australia against Jamaica, and played goal defence during a subsequent Australian series win against New Zealand. In November 2007, she won her first ever world championship title, as the youngest member of the victorious Australian team.
In 2012 it was announced that Corletto would be playing for the New Zealand team the Northern Mystics for the 2013 season, following her husband Daryl Corletto who re-signed with the New Zealand Breakers. After the 2014 ANZ Championship season Corletto signed with Australian team the NSW Swifts after her husband picked up a job with his former ANBL club in Melbourne.
