Papers relating to North Stradbroke Island reflect Kath's involvement in issues such as opposition to sand-mining on the island, and opposition to a proposed bridge connecting North Stradbroke Island with the mainland. There is research material, publications, and correspondence.

Moongalba was established on North Stradbroke Island, by Kath Walker as a cultural education centre in 1971 with the aid of the Aboriginal Arts Board administration grants. It was visited extensively by school children, as well as teachers, students, academics, writers and others. Kath Walker was initially granted a twenty-five year lease to the land by the Redland Shire Council; this was later extended to her lifetime. However, she was never granted legal title to the land, despite the support of many influential people. In 1979 Kath Walker prepared a submission to the federal Department of Aboriginal Affairs, requesting financial assistance and support in obtaining title to the land. Her application was never answered.
