NSW koala baseline survey 2025 - acoustic data

The statewide koala baseline survey is a standalone snapshot of the occurrence, distribution and relative abundance of koalas in NSW in 2025. The baseline survey covers the plausible range of koalas in NSW and over 1,000 sites were sampled across land tenures using heat-sensing drones and passive acoustic recorders. The survey also provides a baseline population estimate from which to evaluate koala population trends over time. \r\n\r\nThis dataset comprises point data of koala presence and absence derived from raw acoustic data, captured from passive acoustic recorders in koala breeding season.
