## 2 Materials and Methods  
Between May and October 2016, White Sharks were captured on SMART drumlines deployed off the east coast of NSW, Australia, at Ballina (\(-\)28.8 S 153.6 E), Evans Head (\(-\)29.1 S 153.4 E), Coffs Harbour (\(-\)30.3 S 153.2 E), Crowdy Head (\(-\)31.8 S 152.7 E), and Tuncurry (\(-\)32.2 S 152.5 E, Figure 1).  
On each fishing day, SMART drumlines were deployed during daylight hours \(\sim\)500 m from shore, following the same configuration used in [PERSON] et al. [52] and [PERSON] et al. [54]. Once an alert of capture was received via phone call, text message, and email, a research vessel traveled to the SMART drumline. When the SMART drumline was retrieved, the trace was immediately attached to a longer rope so the shark could be secured to the side of the vessel using an additional cross-pectoral fin rope to support the body and a tail harness, thereby minimizing potential injuries associated with pressure or crushing. Each shark was secured within five minutes of its arrival.  
Data collected included biological data of sex and lengths (precaudal--PCL, fork--FL, and total--TL to the nearest cm), technical parameters of time of capture and release (h.m), and release location coordinates. All sharks were tagged with dorsal fin-mounted satellite-linked radio transmitting (SLRT) tags following the methods of [PERSON] and [PERSON] [44]. These tags transmit the shark's position to the Advanced Research and Global Observation Satellites (ARGOS) system whenever the dorsal fin breaks the surface of the water. These positions are classified on a scale of decreasing accuracy using seven location classes of 3, 2, 1, 0, A, B, and Z, with class 3 being the most accurate with an error of <250 m, class 2 of 250-500 m, and class 1 of 500-1500 m. Location classes 0 to B provide estimates > 1500 m, while class \(Z\) indicates no position [55].  
Each shark was also tagged with a uniquely numbered identification tag (spaghetti tag, Hallprint, South Australia) to enable individual identification if they were recaptured by other fishers. These tags were inserted into the musculature at the base of the first dorsal fin. As part of a larger research project, acoustic transmitters with transmission intervals

of 40-80 s and a 10-year battery life were surgically implanted into the abdominal cavity following the general procedure described by [PERSON] and [PERSON] [48]. These tags were monitored by an array of 21 Iridium satellite-linked acoustic receivers, which effectively detect tagged sharks in near real-time ([33,56] Vemco VR4-Global--\"tagged shark listening station\"). These tagged shark listening stations were deployed 500 m from shore in 8-16 m of water, with the hydrophone 4 m below the surface. They are designed to detect tagged sharks in the vicinity of up to 400-500 m [57], but shorter-range limits of 150 to 300 m have also been observed [33,50].
