Taxonomy

Scottish-Australian naturalist William John Macleay described the species as ''Raja australis'' in 1884, from specimens collected from a trawl off the south head of Botany Bay. He was excited by the find of a skate species in Sydney waters and wondered about its potential as a food item. He observed, "As an article of food, skate has never been much in favour here, in fact, except in French cafés and places of that kind." It was placed in the genus ''

Distribution and habitat

The Sydney skate is found on the continental shelf off the east coast of Australia, at depths of . Once one of the most abundant skate species the continental shelf off Eastern Australia, the Sydney skate has drastically declined in numbers. Skate species declined in trawl catches off the New South Wales central and south coast by 83% between 1976/1977 and 1996/1997. It is one of four species identified as threatened with extinction by trawling in a 2021 report.
