Dusty Sands wrote in the video description: “Dropping my GoPro off the side of a jetty in Port Noarlunga.
We looked back at the footage and kinda got freaked out when we saw it. We tried dropping the GoPro in at the same spot a few more times but it never showed up again.”
The mysterious object resembled a sea mine, leading many viewers in the comments to urge Dusty to report the find to local authorities.
One commenter wrote, “Strongly suggest reporting it to the coast guard, that looks like a live naval mine that could be dangerous if disturbed.”
Others expressed similar concerns about safety and the potential risks posed by the object, emphasizing the importance of notifying officials to ensure public safety.
Since the object was not spotted again in subsequent drops and no incidents have been reported at the jetty, it appears no immediate danger is present—at least for now.
