Eyewitness account

Eyewitnesses told Mothership that the collision occurred when a boat "speeding" off the lagoon collided with another that was engaged in fishing.

The collision caused five members of the fishing vessel to be thrown overboard.

Of the five thrown overboard, eyewitnesses say that three appeared to emerge without serious injury, with a fourth appearing to be limping and the fifth not emerging from the water.

One eyewitness also told Mothership that one member of the vessel appeared to be "concussed" in the aftermath of the collision, and "was unable to react".

Authorities arrived about 10 minutes later to assist with recovery and rescue efforts.

MPA has issued navigational broadcasts to vessels in the vicinity to keep a lookout for any person in the water.
