In June 2018, Tiatia was awarded the Ravenswood Australian Women's Art Prize, the richest professional art prize for women in Australia. The award, valued at $35,000, was granted on the basis of Tiatia's video installation "The Fall", a production inspired by the Fall of Singapore. In a single take, the five-minute film uses a cast of 30 performers, playing 60 characters, to tell the story of the 1942 battle in a full 360-degree navigation of the space, ending with Tiatia and her camera crew's own image. While the work was commissioned by the Australian War Memorial with the intention of telling a specific historical story, Tiatia also considered "The Fall" an opportunity to hold a mirror up to modern political turmoil. She wanted the project to be a reminder of the failings of history, and hoped that audiences would gain a new understanding of alternate historical outcomes as a part of their examination of the project.
