A diver is fighting for his life after a suspected shark attack off the coast of Albany on Saturday morning, prompting a major emergency response and renewed warnings for people in the area to remain vigilant.

The incident occurred shortly before 11:30am near Michaelmas Island, a popular island destination located off Albany's coastline. Authorities believe the diver was bitten by a shark estimated to be approximately 4.5 metres in length while in the water near the island.

Emergency services were immediately alerted after the attack was reported to the Western Australian Department of Primary Industries and Regional Development (DPIRD) at around 11:30am. Rescue personnel quickly mobilised to provide assistance to the injured man and coordinate a response to the serious marine incident.

Paramedics from St John Ambulance attended the scene and began treating the diver for critical injuries. Authorities have not yet released details regarding the extent of his injuries, but emergency officials confirmed his condition is life-threatening. Medical teams are working to stabilise the victim as efforts continue to provide urgent care.

DPIRD is assisting Western Australia Police with the investigation into the attack. Officials are gathering information about the circumstances surrounding the incident, including the species of shark involved and the events leading up to the encounter.

As a precaution, authorities have urged members of the public to exercise extreme caution in waters surrounding Michaelmas Island and nearby coastal areas. Beachgoers, divers, fishers, and recreational water users have been advised to follow any beach closure notices and remain alert to safety warnings issued by authorities.

The waters around Albany are known for their rich marine ecosystem and are home to a variety of shark species, including great white sharks. While shark encounters remain relatively rare compared with the number of people who use Western Australia's coastline each year, serious incidents can occur, particularly in offshore areas where larger shark species are known to travel.

Michaelmas Island is a popular destination for diving, fishing, boating, and wildlife observation due to its clear waters and diverse marine life. The area attracts both local residents and visitors throughout the year, making safety warnings following shark incidents particularly important.

Authorities have reminded the public that any shark sightings should be reported immediately to Water Police to assist with public safety monitoring and response efforts. Reports from witnesses and nearby vessels may also help investigators determine additional details about the incident.

The attack has sent shockwaves through the Albany community, with many residents closely following updates on the diver's condition. Emergency responders and marine authorities continue to monitor the situation while assessing any ongoing risks to water users in the region.

Further information is expected to be released as the investigation progresses and medical updates become available. For now, the focus remains on the diver's condition and ensuring the safety of people using the waters around Michaelmas Island and the wider Albany coastline.
