Twenty-nine species in five genera of deep-water Galatheidae are reported from southern and eastern Australia increasing the known Australian galatheid fauna from 55 to 74. Species of Paramunida and Agononida are reported for the first time from southern Australia, with a new species of each described, P. antipodes and A. procera. Seven new species of Munida are described (M. aequalis, M. asprosoma, M. chydaea, M. endeavourae, M. isos, M. kapala, and M. spinicruris) increasing the number of known Australian species from 12 to 19. Four new species of Munidopsis are described (Ms. kensleyi, Ms. proales, Ms. tasmaniae, Ms. treis) and three species are newly recorded from Australia (Ms. centrina, Ms. dasypus, Ms. subsquamosa) increasing the known fauna from 11 to 18. Previous records of Ms. dasypus are based on Ms. kensleyi, but we include the first reliable record of M. dasypus from Australia. Previous records of Munida japonica from Australia are referable to M. rogeri Macpherson. Previous Australian records of Munida microps Alcock are referable to two new species, M. endeavourae and M. isos. Previous Australian records of Ms. dasypus are referable to Ms. kensleyi. Raymunida formosanus Lin, Chan & Chu is reported for the first time from Australia. Alcock s (1894) Munida squamosa var. prolixa is recognised as a distinct species of Agononida.
