Within Australia, koala over-abundance has become a serious problem in some areas resulting in signiﬁcant damage to native forests through defoliation. An overabundant Victorian koala population was surveyed for ticks in the autumn of 2016. During the survey 1036 ticks were collected from 158 koalas. All ticks collected were identiﬁed as Ixodes tasmani. Tick prevalence, infestation intensity and on-host sex ratios were calculated for the population. An overview of the ticks and mites associated with koalas in Australia is also presented.
