Walshe works across video, performance, and writing, often engaging with Irish history and contemporary politics of land and sexuality. Much of their work is informed by their queer identity and explores questions of intimacy, kinship, and marginalised sexualities in relation to Irish society. Their 2020 film
The Land Question was produced for
EVA International and has been described as a significant work within their practice, combining archival material with contemporary narratives to examine land ownership, inheritance, and sexuality in Ireland. The work has also been discussed in academic contexts:
John Roberts (philosopher) noted how
The Land Question unravels colonial narratives of enclosure and confinement in Ireland. Walshe's work has been exhibited at venues including
Project Arts Centre and
Temple Bar Gallery and Studios in Dublin, and internationally in group shows. In 2024 they represented Ireland at the
Venice Biennale with a major commission presented in the Irish Pavilion. == Writing ==
