Australia baffled as unidentified mystery object washes up on beach

Police have been baffled by a mysterious "unidentified" dome that washed up on a West Australian beach.

The giant metal object was found by locals at Green Head beach, about 250km (155 miles) north of Perth.

State and federal authorities are investigating the item, which is not currently believed to be from a commercial aircraft.

It is being treated as hazardous, and police have requested people keep a safe distance.

"We want to reassure the community that we are actively engaged in a collaborative effort with various State and Federal agencies to determine the object's origin and nature," police said in a statement.

Green Head beach residents said the cylinder was about 2.5m wide and between 2.5m and 3m long, Australia's public broadcaster reported.
