More unauthorised works have damaged a public beach in Frankston South, as separate enforcement action against a man who admitted building an illegal seawall nearby drags on.

Video captured on Sunday shows an excavator tearing up rocks on the Port Phillip Bay shoreline, south of Olivers Hill.

The Department of Environment, Energy, and Climate Action (DEECA) confirmed to The Age on Tuesday they had not permitted any works on the stretch of Crown land.

“We have been on site to gather evidence,” a spokesperson said.

The Age contacted several property owners and spotted an excavator on a vacant seaside block nearby, but was unable to confirm who was behind Sunday’s digging.
