Police in Western Australia are investigating the discovery of what appears to be human remains stuffed into a plastic bag that washed up on a beach on Rottnest Island.
The grim discovery was made on late on Sunday afternoon at Porpoise Bay, on the southeast of the island, with police immediately called in to investigate fears the bag contained a body.
A WA police spokesman said officers are "fairly convinced" the remains in the bag are human, with a pathologist due to be called in to confirm the find.
The pathologist will examine the contents of the bag either late on Sunday night, or first thing on Monday.
Rottnest Island, situated 18km off the coast of Perth, has been a popular holiday spot for West Australians for generations.
