Ram pressure stripping (RPS) is a hydrodynamical mechanism that can strip ISM material from galaxies as they move through the hot intracluster medium permeating galaxy clusters. Signatures of RPS can be seen in ionised gas emission through the kinematics as well as emission line ratios. A key observational indicator of a ram pressure stripped galaxy is an ionised gas tail of the stripped material. Additionally, galaxies affected by RPS usually have a truncated gas disk compared to the stellar disk. This is because the removal of the ISM as a result of RPS can act to quench star formation. In order to gain a deeper understanding of the RPS process, we perform a detailed analysis of two galaxies from galaxy cluster Abell 119 that were selected from the SAMI Galaxy survey as they showed evidence of quenching due to RPS, 9011900166 and 9011900084. Previous investigations using data from the wide-field IFU KOALA instrument on the Anglo Australian Telescope revealed an ionised gas tail for both galaxies but only ...
