Look-alikes & how to tell them apart

Products often confused with or substituted for Australian King Prawns — and what to look for instead.

Imported Vannamei (whiteleg) prawns

Why confused: Pond-farmed in SE Asia. Visually similar once peeled.

How to tell: Australian prawns are almost always sold shell-on with intact head. Imports are typically peeled, deveined, frozen IQF. Labels must state origin.

Imported Black Tiger prawns

Why confused: Same species (Penaeus monodon) as farmed AUS Black Tigers.

How to tell: Australian product displays origin prominently and typically sells fresh-chilled. Imported is almost always frozen.

The risks of the imported version

Typically imported from: Vietnam, India, China, Thailand

Sulphite preservatives — major allergen, mandatory disclosure when used
Antibiotic and antifungal residues regularly detected at the border
Pond construction has driven mangrove loss across SE Asia
Documented forced-labour cases in parts of the Thai supply chain
