Available wild-caught, these are two almost identical species; Hyperoglyphe antarctica being the main commercial species. Both are caught by droplines and longlines (as well as bycatch of trawling) in marine waters off northern NSW, Queensland, southern WA and Tasmania, as well as Lord Howe and Norfolk Islands.

The main commercial fishery occurs on the continental slope between Sydney and Adelaide (including Tasmania). They are found at depths of 200-600m, remaining close to the seabed during the day and moving up towards the surface at night. Immature fish tend to be found closer to the surface.
