Her father is born in South Africa, to an Irish father and an English mother, and had worked with Micheál Mac Liammóir at Dublin‘s Gate Theatre.

Cusack’s first acting roles are at the Abbey Theatre in Dublin. In 1975, she moves to London and joins the Royal Shakespeare Company (RSC) starring in Dion Boucicault‘s London Assurance in the West End. Her work with the RSC continues with an award-winning performance as Celia in As You Like It which includes the Clarence Derwent Award and her first Laurence Olivier Award nomination.

Cusack makes her Broadway debut in 1984 performing in repertory with the Royal Shakespeare Company. Starring opposite Derek Jacobi, she plays Roxane in Anthony Burgess‘s translation of Edmond Rostand‘s Cyrano de Bergerac and Beatrice in William Shakespeare‘s Much Ado About Nothing, directed by Terry Hands. Much Ado is first produced at the Royal Shakespeare Theatre in Stratford-upon-Avon in 1982–83, then moves to London’s Barbican Centre for the 1983–1984 season where it is joined by Cyrano, before both plays transfer to New York‘s Gershwin Theatre from October 1984 to January 1985, for which Cusack received a Tony Awards nomination for her performance as Beatrice, and costar Derek Jacobi wins the award for his Benedick. The production of Cyrano de Bergerac is later filmed in 1985.

The production also features Niamh’s husband, Finbar Lynch, as Solenyi and Lesley Manville as Natasha. The production wins the three real-life sisters the Irish Life Award in 1992.

One of Cusack’s best known stage roles is Our Lady of Sligo by Sebastian Barry in 1998, in which she plays the principal role of Mai O’Hara in performances in Ireland, on Broadway and at the National Theatre.
