No I am not an expert but lived in the region for over 23 years and spent much time snorkelling (mainly in Kuwait). I imagine that the HMC would have anti-venom.
I always wore a steel handling glove when collecting oysters and was told that if you offer a fist to the sea snake it's head isn't big enough to bite the fist.
Try to push it away with open fingers and it will bite you on the skin inbetween the fingers.
Never had the need to try it though.
