Knowledge about the breeding location and abundance of migratory and non-migratory seabirds has been used over the past decade to address fundamental questions in marine research. Up to date, no consistent sea bird breeding data is present for the Australian offshore islands. Here, we present a collated and homogenized data collection of records made on breeding populations from Australian offshore islands. Records were collected from all available sources spanning a timeframe from 1902 – 2023. Record numbers were manually quality checked and locations adjusted based on original comments and satellite imagery. We present data of 1043 locations situated in Australian offshore waters, including Norfolk Islands and the Subantarctic islands. Breeding numbers of any additional, non-seabird species are also given.The data set is designed to be used to inform conservation and planning and serves as a base line for future research.
