N1 - Funding Information:
This work would not have been possible without the generous funding provided by Holsworth Wildlife Research Endowment (grant HLS-18-005) and the Stuart Leslie Bird Research Award provided by Birdlife Australia (grant FOST-18-416). We thank the AWSG, VWSG, Friends of Shorebirds South East (FOSSE), Rosalind Jessop, and the late Dr Clive Minton for their help with this project; assistance with permits, access to captured birds, and a deep understanding of the behaviour and movements of the shorebird species in Roebuck Bay have proved invaluable. We are enormously grateful to Stoate family of Anna Plains Station for hosting part of the field work. We acknowledge the Yawuru People, via the offices of Nyamba Buru Yawuru Limited, for permissions granted to AWSG to capture birds on the shores of Roebuck Bay, the traditional lands of the Yawuru people. We also acknowledge the Karajarri and Nyangumarta people for permission to catch birds to be sampled for this project on the shores of 80 Mile Beach, traditional lands of the Karajarri and Nyangumarta people. Open Access publishing facilitated by Federation University Australia, as part of the Wiley - Federation University Australia agreement via the Council of Australian University Librarians.

N2 - Antibiotic resistance is an ongoing threat to both human and animal health. Migratory birds are a potential vector for the spread of novel pathogens and antibiotic resistance genes. To date, there has been no comprehensive study investigating the presence of antibiotic resistance (AMR) in the bacteria of Australian shorebirds or terns. In the current study, 1022 individual birds representing 12 species were sampled across three states of Australia (Victoria, South Australia, and Western Australia) and tested for the presence of phenotypically resistant strains of three bacteria with potential to be zoonotic pathogens; Escherichia coli, Enterococcusspp., and Salmonellasp. In total, 206 E. coli, 266 Enterococcusspp., and 20 Salmonellasp. isolates were recovered, with AMR detected in 42% of E. coli, 85% of Enterococcusspp., and 10% of Salmonellasp. Phenotypic resistance was commonly detected to erythromycin (79% of Enterococcusspp.), ciprofloxacin (31% of Enterococcusspp.) and streptomycin (21% of E. coli). Resident birds were more likely to carry AMR bacteria than migratory birds (p ≤.001). Bacteria isolated from shorebirds and terns are commonly resistant to at least one antibiotic, suggesting that wild bird populations serve as a potential reservoir and vector for AMR bacteria. However, globally emerging phenotypes of multidrug-resistant bacteria were not detected in Australian shorebirds. This study provides baseline data of the carriage of AMR bacteria in Australian shorebirds and terns.
