Help Identify What These Are #natureismetal #keepnaturemetal #unidentified

Here's the description left on our submission page:

"These are two recordings of a surfline live webcam. This camera is facing Kirra point in the Gold Coast of Australia and was filmed around 6pm on the 7th of April 2024. The two recording were taken about 5 minutes apart and are in real time. You can see fluorescent lights (swimming)past the coast heading south. I’ve considered almost every possible thing from light reflections to ufos to marine animals but these things seem to be jumping in and out of the water at an abnormal speed I would love to know what you think these are. I’ve been racking my brain for a few days over this."
