Serra made her international debut in 1966 as Eleonora in Cimarosa's "" at the Hungarian State Opera House in Budapest, but did not achieve general acclaim until the late 1970s, when she took on coloratura roles in Donizetti's "Lucia di Lammermoor" and Bellini's "La sonnambula". In 1988, Serra debuted at the Vienna State Opera singing the Queen of the Night in a new production of "Die Zauberflöte" conducted by Nikolaus Harnoncourt and staged by Otto Schenk.
