The Draughtboard shark is endemic to Australia, occurring from the central coast of New South Wales, around the temperate south of the country, including Tasmania, to south-eastern Western Australia.
It is a benthic species that occurs most commonly in continental shelf and continental slope waters down to at least 650 m, but is sometimes seen by divers in relatively shallow waters.
Females lay distinctive flask-shaped egg cases that have 19 to 27 strong transverse ridges. The egg cases are laid on the bottom where the tendrils attach to bottom-dwelling invertebrates and seaweed.
