Juvenile white sharks (Carcharodon carcharias) occupy nearshore coastal waters along eastern Australia, often overlapping with beach goers. Understanding how these sharks behave in shared spaces is central to managing coexistence. We deployed animal-borne camera and accelerometer packages with towed satellite tags on 20 juvenile white sharks off New South Wales to characterise their fine-scale behaviour and habitat use. From 68.5 h of video footage across 11 sharks, white sharks spent most of their time along the seafloor in sandy, low-complex habitats. While sharks encountered potential prey frequently, pursuits were highly selective and predation attempts rare. We then applied hidden Markov models to 2,087.5 h of accelerometer and movement data from 18 sharks to identify three behavioural states: directed linear swimming, area-restricted search (ARS), and looping. All three states were performed by all sharks but were not explained by body size or sex. Spatial, temporal, and environmental drivers were explored using binomial generalised additive mixed models which showed that time of day, temperature, and terrain were all significant drivers of behavioural performance. High-activity bursts (VeDBA > 0.25 g, > 4 s) were most associated with ARS and daylight. Linear swimming occurred primarily from dusk to dawn, while looping occurred during the day. Area-restricted search was the most variable state, occurring both horizontally along the seabed and vertically through the water column, likely searching for and tracking prey. Looping was performed at the surface during the day, with 56% of circling bouts sustaining one rotational direction before switching to other, which is consistent with uni-hemispheric sleep common in birds and marine mammals, where circling direction reflects the resting hemisphere. Together, these approaches move beyond describing where juvenile white sharks occur to revealing what they are doing in shared coastal waters.
