She also acted as stand-by presenter for ABC News South Australia when the regular presenter were absent.

She then moved to the Seven Network in 2004. At 7 she became a main fill-in presenter of *Seven News Adelaide *, as well as a senior reporter. She also presented the news on *Sunrise * on two occasions including while the show was live in Disneyland. She began acting as substitute presenter on *Today Tonight * in 2005.

Following Leigh McClusky's announcement about her departure from *Today Tonight South Australia * on 17 August 2007, there was speculation about Mangiarelli being the replacement host. ^[2] This proved correct and Seven announced that Mangiarelli would be the new presenter, replacing McClusky (who had presented the show since its inception in 1995).

In July 2017, Mangiarelli began presenting the Adelaide edition of Seven Afternoon News, while retaining her duties presenting Today Tonight.
