One SMART drumline failed to set off an alert at Whale Beach, Sydney on 15 March 2019. When the contractor arrived at the respective drumline for retrieval at the end of the day, a Smooth Hammerhead was found dead on the line (Table 1). The trigger was still intact and failed to dislodge.
All other sharks were released alive.
