A crime scene was established and police are now working to figure out further details, including whether the matter is suspicious.

Anyone with information is urged to contact police.

In January, human remains were found in the backyard of a Victorian holiday home on Phillip Island during plumbing works.

The plumbers were digging a trench to replace a sewer pipe when one of the workers made the shocking discovery about 50cm below the surface.

“He just pulled a bit of sand out and emptied his bucket, and that’s when he saw the human head,” witness Riley Weinzierl told 7NEWS at the time.

“The rest of them stopped excavating at that point and had a look around in the sand, and there were a few more bones and things.”
