Beach-goers told to clear off as whale beaches itself

A dead whale has washed up on a beach on Victoria's Mornington Peninsula.

The Humpback whale washed up at Boag Rocks, near Gunnamatta beach, on Monday.

It's about nine metres long and could weigh up to 20 tonne, with authorities urging beachgoers to steer clear of the carcass until it's removed.

The beach remains open but people are warned the whale could attract sharks.
