Police have pulled two people from the water after a boat they were on went up in flames in Melbourne's Port Phillip Bay.
Fire crews were called to the emergency about two nautical miles off Elwood Beach, in the city's south-east, just after midday.
Fire Rescue Victoria (FRV), Border Force and Victoria Police were all involved in the emergency response.
FRV commander Kieran Lenehan told ABC Radio Melbourne firefighters extinguished the blaze, but the boat sank due to extensive damage.
"Fire Rescue Victoria are still on scene and working with Ports Victoria and private contractors to ensure any debris or any contaminants are being contained and managed correctly," he said.
More to come.
