P.L.C flourished under Carson's leadership, and the Spreydon property soon proved too small. Margaret Ann Cameron, the owner of the Fairholme Homestead on the Range in East Toowoomba, soon expressed to the Church her desire to establish a girls' school, having previously taught her daughters and other children in Glen Innes, New South Wales during the 1860s. Cameron passed ownership of her property to the Presbyterian Church, and under a new constitution, Carson, together with the College board, opened the Presbyterian Girls' College, Toowoomba in the Fairholme property with 59 students. The relocation of the school was achieved over two stages: the primary departments moved in July 1917, and the rest of the school in January 1918. The motto which was used at The Presbyterian Ladies College Limited, "Ardens sed Virens" ("Burning yet Flourishing") was adopted for use at Fairholme.
