Kramer, and his family, moved to Alice Springs in 1923. In 1925, he was appointed
Missionary for Central Australia by the
Aborigines' Friends' Association where he helped local
Arrernte people living in the town while also making frequent 'bush trips' in the cooler months by camel-team and motor car; taking with him food and medicines. according to traditional law led Kramer to demand the prosecution of the killers for murder, leading to debate on the applicability of white law to traditional violence. The men were tried but acquitted by a Darwin jury. In the early 1930s Kramer's relationship with the Aborigines' Friends' Association began to fracture and, with the increasing European population following the completion of the railway, forcing Aboriginal people out Alice Springs and attendance at the church went from 50 Aboriginal people to less than 10. It was for these reasons, and his increasingly poor health, that in 1934 Kramer retired and he and Euphemia returned to Melbourne where both continued to campaign for Central Australian Aboriginal welfare. == Later life ==
