Specialist police have exploded a dangerous device found on a popular beach on Queensland's Sunshine Coast.
Video shows the device exploding on the empty beach by the water.
The Department of Defence has confirmed the device was a "marine marker" – a smoke-and-flame pyrotechnic device commonly used in search and rescue operations, anti-submarine warfare and maritime research.

"Defence can confirm a Marine marker was located in the vicinity of Peregian Beach, Sunshine Coast on 22 August 2025," a spokesperson said.
"Defence assessed the unexploded ordnance (UXO) at the scene. The UXO was assessed as unsafe for transport and were disposed of onsite.
"Defence routinely assists state and territory policing agencies in the safe recovery or disposal of suspected unexploded military ordinance found in public areas."
It is not clear how the device came to be on the beach or how it was found.
Police made an emergency declaration under the Public Safety Preservation Act (PSPA) and cordoned off a large area surrounding the device at 12.30pm.
The PSPA has since been revoked and the area declared safe.
The exclusion zone encompassed David Low Way from Podargus Parade to Woodland Drive, including Martin Street, Avocet Street, Peregian Esplanade, Parakeet Crescent, Egrer Street, Teal Street, Currawong Crescent, Osprey Avenue, Tern Street, Garnet Street, Ibis Street, Pelican Street, and Kingfisher Drive.
