A Surf Cam in Western Australia Caught Something Large Moving Through the Water. Nobody Agrees on What It Is.

Swellnet operates a network of surf monitoring cameras along the Australian coastline. Their camera positioned at Scarborough, Western Australia, was rolling on a moody, rainy Saturday morning in late March 2026 when it caught something large moving through the water offshore. The footage is grainy. The object is a large black mass, distinctly organic in appearance, moving through the lineup at a pace and in a manner that prompted Swellnet’s own staff to share it publicly and ask for help identifying it. NUFORC has also fielded reports from the area. The footage has spread across surf, cryptid, and paranormal communities, with proposed identifications ranging from whale shark to oarfish to something without a name. It has not been definitively identified.

Swellnet posted the footage to their social media accounts with a caption that reflected their own uncertainty: “Our Scarborough surf camera captured this incredible specimen swimming on a moody, rainy Saturday the weekend just gone. In the office we’re thinking it’s a shark, and with the incredible size, a possible whale shark? If it’s a white, it’s an absolute submarine.”

The “submarine” comparison is the operative detail. Whatever is in the frame is large. Not ambiguously large — visibly, undeniably large, in the way that makes people stop scrolling.

The footage captures a dark, elongated mass moving through the water near the surface. It does not have the lateral tail movement of a shark. It is not kelp — it moves too deliberately and too quickly. It passes through the frame on what appears to be a purposeful trajectory. On Swellnet’s standard surf cameras, the field of view covers enough of the lineup to establish scale context, and the object fills a substantial portion of that frame.

What Viewers Said

The clip traveled quickly. Comments from the surf community split into the predictable clusters: the rational, the cautiously speculative, and the immediately cryptid-inclined.

Among the more considered responses: “It’s not a shark — no side to side movement at all.” This observation is significant. Sharks swim via lateral body undulation, a motion that is distinctive and visible even in grainy footage. The object in the Swellnet clip does not demonstrate that motion. This either rules out sharks or indicates the footage quality is too low to resolve it, depending on who you ask.

The oarfish theory was the strongest conventional candidate circulating in the days after the post. Oarfish — the world’s longest bony fish, reaching up to 11 meters in some documented cases — are rarely filmed in the wild. They inhabit deep water and surface only occasionally, often when disoriented or dying. One commenter specifically noted the recent passage of Cyclone Narelle through Western Australian waters as a possible explanation for an oarfish appearing in shallow coastal waters: “Consensus is that it is an oarfish, maybe disoriented after Cyclone Narelle.”

Whale shark was the other serious candidate. Whale sharks regularly appear in Australian waters and can reach 12 meters or more in length. At the scale suggested by the footage, a whale shark is plausible — but whale sharks are filter feeders that swim slowly near the surface with a distinctive back-and-forth body motion. Whether the footage shows that motion is contested.

The NUFORC Connection

The National UFO Reporting Center received a separate but related report from the Scarborough area in the same timeframe — a sighting of an “alien orb caught studying wildlife.” The proximity of the two reports, combined with the timing after Cyclone Narelle, has not gone unnoticed in fringe communities, though no link between the two events has been established.

What the footage shows is a large, unidentified organism moving through coastal water on a rainy Saturday morning off Western Australia. Swellnet’s cameras keep rolling regardless of what swims past. Most of the time it is nothing unusual. This time, it was something that nobody in the room could name.
