The Institute of the Sisters of Mercy of Australia and Papua New Guinea (ISMAPNG) is involved with eleven fully sponsored and two co-sponsored secondary schools in Victoria, South Australia and Western Australia.

Mercy Education is the delegated authority responsible for operating the schools and assists the Institute Leader in fulfilling her role as one of the Governors of the co-sponsored schools. Mercy Education Limited also supports the works and promotes the Mercy ethos in the Mercy schools across Victoria, South Australia and Tasmania.

The governance role of the Board of Mercy Education is confined to the sponsored schools and sets policies, appoints Principals, approves senior leadership positions and fulfils due diligence in the area of finance and audit management, capital development, risk management and litigation.

The existence of the Mercy Education Limited gives strength, support and solidarity to each of the member Mercy schools and its community.
