Look-alikes & how to tell them apart

Products often confused with or substituted for Australian Western Rock Lobster — and what to look for instead.

Imported warm-water lobster / slipper lobster
Why confused: Sometimes sold as generic 'lobster' in frozen form.
How to tell: Australian Rock Lobster is sold alive or whole-cooked. Labels are explicit — 'Southern Rock Lobster' or 'Western Rock Lobster'.
Imported Maine / Canadian lobster
Why confused: True-claw lobster (Homarus americanus); confused by consumers unfamiliar with Australian spiny lobster.
How to tell: Australian rock lobsters have no large claws. If it has massive front claws, it's a cold-water Atlantic lobster.

The risks of the imported version

Typically imported from: Canada, USA, Cuba

  • MSC equivalence not always present in imported origins
  • Frozen-thawed product common — texture suffers
  • Live transit by air freight is high carbon
