  abstract = {{I}n understanding the impact of commercial whaling, it is important to estimate the mixing of low latitude breeding populations on {A}ntarctic feeding grounds, particularly the endangered humpback whale populations of {O}ceania. {T}his paper estimates the degree of genetic differentiation among the putative populations of {O}ceania ({N}ew {C}aledonia, {T}onga, the {C}ook {I}slands and {F}rench {P}olynesia) and {A}ustralia (western {A}ustralia and eastern {A}ustralia) using ten microsatellite loci and mt{DNA}, assesses the power of the data for a mixed-stock analysis, determines ways to improve statistical power for future studies and estimates the population composition of {A}ntarctic samples collected in 2010 south of {N}ew {Z}ealand and eastern {A}ustralia. {A} large proportion of individuals could not be assigned to a population of origin (> 52%) using a posterior probability threshold of > 0.90. {T}he mixed-stock analysis simulations however, produced accurate results with humpback whales reapportioned to their population of origin above the 90% threshold for western {A}ustralia, {N}ew {C}aledonia and {O}ceania grouped using a combined mt{DNA} and microsatellite dataset. {R}emoving the {C}ook {I}slands, considered a transient region for humpback whales, from the simulation analysis increased the ability to reapportion {T}onga from 86% to 89% and {F}rench {P}olynesia from 89% to 92%. {B}reeding ground sample size was found to be a factor influencing the accuracy of population reapportionment whereas increasing the mixture or feeding ground sample size improved the precision of results. {T}he mixed-stock analysis of our {A}ntarctic samples revealed substantial contributions from both eastern {A}ustralia (53.2%, 6.8% {SE}) and {N}ew {C}aledonia (43.7%, 5.5% {SE}) [with {O}ceania contributing 46.8% (5.9% {SE})] but not western {A}ustralia. {D}espite the need for more samples to improve estimates of population allocation, our study strengthens the emerging genetic and non-genetic evidence that {A}ntarctic waters south of {N}ew {Z}ealand and eastern {A}ustralia are used by humpback whales from both eastern {A}ustralia and the more vulnerable breeding population of {N}ew {C}aledonia, representing {O}ceania.},
