A cyclist has filmed an "unnerving" encounter with a group of kangaroos on Melbourne's north-eastern outskirts.

Ben Vezina was riding in Hawkstowe Park near Hurstbridge on Sunday when he came across the mobbing marsupials down a deserted dirt track.

In a YouTube scene reminiscent of a horror film, many of the eastern greys stand stock still as Mr Vezina slowly rolls past, eyeballing the camera.

"I feel like ... oh my God ... instead of a zombie apocalypse, it's a f---ing kangaroo [apocalypse]," he says, as the camera pans past the animals.
