This collection of photographs illustrates the life of Rev Isaac Neilson Whyte and Dr Mary Grace Whyte durng their service with the Australian Presbyterian Board of Missions in the New Hebrides, 1952-1957. With their children Michael, Robyn, Alistair and Peter, they were based in the village of Wintua in the South West Bay region of Malekula. Mary Grace and Neilson arrived in Wintua shortly after a hurricane had been through and destroyed much of the village infrastructure. In the years that followed, Wintua was rebuilt with the help of people from neighbouring villages, who helped to build a new church, mission house, district school and a small hospital. Rev Whyte was often away from Wintua, visiting other villages in his mission jurisdiction. He visited Big Nambas territory, which had in the previously been hostile to Europeans, and helped bring about a peace agreement between village leaders. Mary Grace practised medicine in Wintua and surrounding villages.

This collection of photographs depicts village and church life in South West Bay. It shows the reconstruction of the village, family photographs, Rev and Dr Whyte giving medical care and travel between villages by launch and canoe. There are also photos of a Big Nambas village and the Leviamp peace talks, as well as family photos taken on return to Australia.
