A diver was attacked by a shark at Bruny Island, a popular tourist destination off the coast of Tasmania, sustaining an arm injury. The incident comes amid a string of beach closures along Tasmania's east coast after a series of shark sightings in recent times, heightening concerns about shark activity in the region's coastal waters.

Details of the attack itself, including the diver's condition and the exact circumstances, were not fully provided in the available report. The wider context is a run of precautionary beach closures along the east coast following multiple shark sightings, suggesting authorities have been on alert for increased shark presence in the area even before this latest attack occurred.
