It's a fair way from the sea, but hundreds of seagulls have descended on Dandenong, as if in a scene from Hitchcock's horror film The Birds.

The marine birds have been found nesting on roofs in the outer south-eastern Melbourne suburb, potentially causing thousands of dollars damage to businesses.

Greater Dandenong City Council mayor Jim Memeti​ said he had been living in the area for 40 years but had never seen it like this before.

"We have got hundreds and hundreds of seagulls," he said.
