Australian wild King Prawns from Spencer Gulf vs farmed imported prawns from Vietnam, India, and China.
How King Prawns compares to imported equivalents on key nutrients.
Vietnamese, Indian and Chinese farmed prawns are cheaper because of lower-cost ponds, lower wages, lower biosecurity bar and bulk frozen freight. Spencer Gulf wild prawns are wild-caught, MSC-aligned and never frozen at sea on the best vessels.

Methodology: Carbon range for imports is wide depending on whether ponds replaced mangrove (high) or rice paddy (lower).
Australia: Brief tow times; rapid chill at sea
Imported: Pond-grown; antibiotic residues sometimes detected
Australia: Low — covered by AFNS
Imported: Moderate — sulphite and species substitution documented
Australia: Vessel-to-plate
Imported: Limited; pond-level rare
Spencer Gulf prawns are world-class — sustainable, fresh, lower-carbon, and never use sulphites. Imports are cheaper but carry welfare, residue and ecosystem-conversion risks.
