Her debut occurred in 1973, on the stage of the Baltic State Opera House in Gdańsk, in the title role of Carmen, and her fame and prestige began accordingly. Initially, her activity was centered locally in Gdańsk, where she kept her position as the leading soloist in the Baltic State Opera, making also frequent guest visits to other opera houses.

Her first appearance outside of Poland took place in Basel, when she sang the role of Amneris in Aïda, in 1977. Soon after, with her international career established, she gave a farewell performance in Gdańsk on 15 July 1979, as Dalila, no longer singing regularly for the Baltic State Opera, eventually moving out of Poland and establishing her permanent residency in Vienna, her career centered from now on at the Staatsoper. From there, she made frequent guest visits to sing on stages of various opera houses around the world, including her native country, particularly at the Teatr Wielki, Warsaw. On 16 September 1979 she made her American stage debut in the San Francisco Opera, as Laura in La Gioconda, which was telecast "live" around the world.
