Distribution by collection data
It is usually found on rocky or soft bottoms at depths between 22 m and 103 m.
It has a high edibility rating. Angler, David Moore stated that "A 'family fight' ensued over the last fillet left on the plate! The flesh was white, moist and flaky. It drew comparisons with the way smoked cod comes apart on the fork. It was both attractive to the eye and delicious. It was up against snapper and pearl perch and was “better than both” as voted by a family of four that eat a lot of fish."
