There is little information on. predation on koalas Phascolarctos cinereus. Predators are considered to include dogs, dingoes, raptors and large goannas (Marchant and Higgins 1993, Martin and Handasyde 1999, Melzer et al, 2000). Martin and Handasyde (1999) report that the Geelong Field Naturalist Club often found the remains of young Koalas under the roost of a pair of Powerful Owls Nixon strenua. Barnard (1925) reports on the diet of Powerful Owls but does not find Koala amongst the possums, gliders, flying foxes and birds seen with the Powerful Owl. He does implicate the Wedge-tailed Eagle Aquila audax, however. Barnard (Le Souef 1918) reports seeing more than one Wedge-tai led Eagle "... eating a half grown koala .. , that they had evidently just Killed". Later he (Barnard 1925) reports seeing them "... kill native bears". We (Melzer) have received an account from Biloela (west of Gladstone QLD) of a young Koala being "snatched" from branches just above its mother by an unidentified raptor. Here we provide three additional accounts of predation, or attempted predation, on Koalas from central and south-east Queensland.
