  abstract = {{G}roups or aggregations of animals can result from individuals being attracted to a common resource or because of synchronised patterns of daily or seasonal activity. {A}lthough mostly solitary throughout its distribution, white sharks ({C}archarodon carcharias) seasonally aggregate at a number of sites worldwide to feed on calorie-rich pinnipeds. {A}t the {N}eptune {I}slands, {S}outh {A}ustralia, large numbers of white sharks can be sighted throughout the year, including during periods of low seal abundance. {W}e use a combination of photo-identification and network analysis based on co-occurrence of individuals visiting the site on the same day to elucidate the population structure and aggregatory behaviour of {A}ustralia's largest aggregation of sub-adult and adult white sharks. {W}e photo-identified 282 sharks (183 males, 97 females, 2 unknown) over a 4.5-year period ({J}une 2010-{N}ovember 2014) and found that white sharks did not randomly co-occur with their conspecifics, but formed four distinct communities. {T}endency to co-occur varied across months with males co-occurring with more individuals than females. {S}ex-dependent patterns of visitation at the {N}eptune {I}slands and resulting intraspecific competition likely drive the observed community structure and temporal variability in co-occurrences. {T}his study provides new insights into the aggregatory behaviour of white sharks at a seal colony and shows for the first time that white shark co-occurrence can be non-random.},
