A council in eastern Victoria has issued a warning about potentially dangerous pine cones falling from a tree in the town of Warragul.

The 120-year-old heritage-listed bunya pine in the grounds of the Courthouse Hotel has been dropping huge pine cones.

The Baw Baw Council says they weigh up to 10 kilograms each.

Mayor Diane Blackwood says the cones are potentially lethal.

"These things are enormous," she said.

"They are the size of a watermelon, falling literally out of the sky from potentially 20 metres high.

"So you wouldn't want to be under one, I tell you."

The area was cordoned off while council workers removed the remaining pine cones.
