Abstract: <jats:title>Abstract</jats:title><jats:p>Genetic variation, and the way in which it is partitioned among populations, has implications for a species' survival and evolutionary potential. Such information is particularly important for the successful conservation and management of species that have experienced past human impacts and potential losses of genetic diversity. Overharvesting of the Australian fur seal <jats:italic>Arctocephalus pusillus doriferus</jats:italic> in the 18th and 19th centuries resulted in severe population reductions and elimination of an estimated 17 of 26 colonies. Currently, the subspecies is recovering and <jats:italic>c</jats:italic>. 20 000 pups are produced annually at 13 colony sites, most of which are situated in Bass Strait in south‐eastern Australia. Genetic analysis of samples collected from pups captured at nine colonies revealed no difference in allelic diversity or heterozygosity at five microsatellite loci and no differences in haplotype diversity within a 344 bp region of the mitochondrial DNA control region. There was some evidence for isolation by distance but the program <jats:sc>structure</jats:sc> predicted a single cluster of individuals. Gene flow among colonies appears to be substantial at present, indicating that the Australian fur seal is currently a single, panmictic unit.</jats:p>
