The species has also been recorded from Jervis Reef near Badu Island, approximately 90 km N of the tip of Cape York Peninsula.
Inhabits shallow, coastal areas in seagrass beds and occasionally on rocky and coral outcrops.

Body & tail slender, tapering posteriorly; snout rounded anteriorly, nostrils terminal with small nasal barbels; interdorsal space relatively long, much greater in length than forst-dorsal-fin base, ~12.1% TL; snout-vent length ~30.1% TL.
Dorsal fins relatively large and angular, about equal in size; first dorsal fin hieght 7% TL; second drosal fin height 7.8% TL; caudal fin with a pronounced subterminal notch but without a ventral lobe.

Etymology

The species was named in honour of Edward Hallstrom, a former Director of the Taronga Zoological Park in Sydney, Australia.
