ABSTRACT Aim Freshwater ecosystems cover less than 3% of the Earth's surface, yet support nearly 10% of all known animal species, majorly represented by freshwater fishes and amphibians, both of which are highly threatened groups. Geographically isolated freshwater species, such as those inhabiting islands, are at high risk. Australia, with nearly 9300 islands, is home to diverse island freshwater fauna. However, the lack of published literature on their island occurrence, threats and management impedes effective conservation across islands. We aim to describe the distributional patterns of amphibians and freshwater fishes on islands and analyse the island characteristics that influence these patterns. Location Australia's Islands. Methods We compiled the first database of occurrences of amphibians and freshwater fishes across Australia's islands. Utilising the database, we used regression analysis to examine the main drivers of distributional patterns, species richness and species composition on Australia's islands. Results We found that 102 amphibians and 95 freshwater fishes occur on Australia's islands. Fifty‐five fishes were obligate freshwater species, 21 were euryhaline and 19 were diadromous. Although freshwater fishes showed lower richness on islands than amphibians, potentially due to lower survey efforts, fishes had a higher proportion of threatened and alien species. Islands with more precipitation that are closer to the mainland hosted higher amphibian richness, which likely retained mainland amphibian assemblages or were more easily colonised. In contrast, larger islands hosted higher freshwater fish richness, where diverse habitats were likely to sustain more species. Main Conclusions Using the new database compiled, we found that occurrences of amphibians and freshwater fishes on islands were influenced by climate, island size and distance from the mainland. This provides a baseline for follow‐up studies on phylogeny and biogeography. This research contributes to future conservation of amphibians and freshwater fishes on islands by revealing islands of potential conservation concern and lays the groundwork for future spatial prioritisation work.
