A strange barnacle-covered object discovered on the southern end of Wongaling Beach has sparked plenty of curiosity among locals, with the mystery item believed to be part of a device used by commercial fishing vessels to locate fish at sea.
Mission Beach’s Linden Carney who came across the circular object shared photographs online asking if anyone knew what it could be, prompting several suggestions however, its appearance and identification markings suggest it may be a satellite tracking buoy associated with a drifting Fish Aggregating Device, commonly known as a FAD.
Photographs show the identification number ISL+274267 on the object, although exactly where it came from, who owns it and how far it travelled before reaching Wongaling Beach remain a mystery.

FADs are used by commercial fishing vessels to help locate fish such as tuna, which naturally gather around floating objects in the ocean. Drifting versions can be fitted with satellite tracking equipment and, in some cases, sonar, allowing fishing crews to follow the device and detect fish gathering beneath it.
Judging by the marine growth covering the Wongaling Beach find, the unusual object certainly appears to have spent some time at sea before its arrival on the Cassowary Coast, and it’s not the first mysterious object to turn up on a nearby North Queensland beach in recent months.
In early July, six large spherical metal objects washed ashore at Forrest Beach, near Ingham, attracting national and international attention. Authorities established a safety exclusion zone while the objects were investigated, with the Australian Space Agency later saying they appeared consistent with pressure vessels from a space launch vehicle.
While the Wongaling Beach discovery appears to have a much more earthly explanation, it has once again sparked plenty of curiosity about what can travel across the ocean before eventually finding its way onto Far North Queensland's shores.
