Police officer rescues dolphin stranded in low-tide on Gold Coast beach

Police officers are used to putting their lives on the line to protect others, but what about when they put themselves in the ocean to save a different type of mammal?

A Gold Coast officer has done just that, wading into the shallows to help a dolphin that had become trapped.

Video, exclusive to 9NEWS, shows the man, who is fully dressed in his entire uniform,  thigh-deep in the ocean attempting to coax the dolphin back into deeper waters.

“How could it get stuck there?” onlookers can be heard saying.

After a few moments, the officer gives the dolphin one last push and it swims off, as he throws his hands up in the air, jubilant.
