Liturgy texts for the Australian solemnity of Mary McKillop are available. I know I don’t have many readers from Oz, but a few notable things: Entrance and Communion antiphons, but nothing for “Offertory”/Preparation of Gifts.
Rome affirmed a request by that nation’s bishops:
The Congregation for Divine Worship and the Discipline of the Sacraments has approved a request from the Australian Catholic Bishops Conference that the liturgical observance of St Mary of the Cross MacKillop be raised from a “feast” to a “solemnity.” Each year on the 8th of August the “feast day” of Mary MacKillop has traditionally been marked in parishes and a special Mass is often said, particularly in places where the Sisters of Saint Joseph have a presence.
And a liturgical reminder of what the elevation to solemnity entails:
A solemnity will mean that the Mass of the day will include a first reading as well as the second reading. It will also include the Gospel, the Gloria and the recitation of the Creed. This honour is a recognition that the story of and devotion to St Mary MacKillop has a prominent place in the Catholic community in Australia.
