  abstract = {{U}nderstanding the biological connections between populations is essential to wildlife management and conservation. {G}enetic studies play a central role in characterizing these connections, but typically require stratified sampling regimes to assess the spatial extent and strength of gene flow, and the relative influences of sex and ontogeny on patterns of connectivity. {Y}et, this can be challenging in some study systems, particularly in large marine species such as sharks, where genetic studies often rely on opportunistic and/or sampling conducted over large spatial scales. {W}e demonstrate the importance of stratified sampling to identify previously undetected genetic structure in tiger sharks ({G}aleocerdo cuvier) off eastern {A}ustralia, where panmixia has been previously reported. {W}e performed population genomic analyses on 414 tiger sharks, representing males and females and both juvenile-subadult and adult-life stages, and 21 locations spanning approximately 3000 km of eastern {A}ustralia and the {I}ndo-{P}acific region. {S}imilar to previous studies, we demonstrate a lack of overall genetic structure across the sampling area; however, our analysis shows evidence of spatial autocorrelation and local genetic structuring in juvenile-subadult female tiger sharks. {T}hese results point to potential influences of sex and ontogeny on patterns of population genetic structure and connectivity in {A}ustralian tiger sharks. {W}e discuss these findings in the context of essential habitats supporting tiger shark populations and risks of overstating the strength of biological connections among shark populations in the absence of appropriate sampling regimes.},
