Crab ID?

[ChrisReefer02]

Hey everyone, need help identifying this crab, was sold to me as a emerald crab, I have some doubts. Emeralds crabs are pretty hard to find in Australia, soo thought I would take the chance and buy it, just seeing if anyone can confirm if its a emerald crab, or a pest crab.
Thank you in advance

This a completely non expert opinion, but from someone that has a lot of emerald crabs, the end of the claws on all of mine look more like suction cup’s/scrapers. Those look very pointed, so I can say that they don’t look like any of mine. I hope you better a more scientific answer from others on here.
