Hammerhead sharks (family Sphyrnidae) are among the world’s most threatened shark groups, with fisheries interactions remaining a major conservation concern due to their life-history characteristics, coastal habitat use, and sensitivity to capture stress. In 2024, all hammerhead shark species became ‘no-take’ in Queensland, requiring mandatory release of all individuals captured in the East Coast Inshore Fin Fish Fishery (ECIFFF). However, little is known about the outcomes of these interactions or whether no-take regulations are effectively reducing fishing-related mortality. This study presents the first fishery-wide assessment of hammerhead shark interactions following implementation of no-take regulations, using Fisheries Queensland eFisher logbook data from October 2024 to October 2025. A total of 1,674 hammerheads were reported across the five ECIFFF management regions, comprising great hammerheads (Sphyrna mokarran; n = 863), scalloped hammerheads (S. lewini; n = 734), winghead sharks (Eusphyra blochii; n = 40), and smooth hammerheads (S. zygaena; n = 37). Reported captures were dominated by great and scalloped hammerheads, with substantial variation in discard outcomes among species, regions, and months. Scalloped hammerheads were the only species reported alive following capture, with approximately half of individuals recorded alive, whereas all reported great, smooth, and winghead sharks were recorded as dead. Reported species composition also highlighted ongoing challenges with species identification, particularly among morphologically similar hammerhead species. These findings provide the first assessment of hammerhead shark discard outcomes in Queensland’s ECIFFF following implementation of no-take regulations, demonstrating that mandatory release alone may not eliminate fisheries impacts. The results highlight priorities for improved species identification, reporting practices, and validation of post-release survival to inform future bycatch mitigation and evaluate management effectiveness.
