Swimmer Fatally Attacked by Bull Shark in Georges River, Sydney

A well-documented early 20th-century bull shark attack in a tidal river 10–12 miles from the sea, featuring a sustained multiple-bite assault with detailed forensic documentation by Dr. Arthur Palmer and preserved in the Coppleson Archives, giving it strong scientific and archival significance.

On the afternoon of January 28, 1906, William Joseph Dobson, a 33-year-old ironmonger from Petersham, was spending leisure time with companions at Georges River near Como, New South Wales, approximately 10 to 12 miles upstream from the sea. At approximately 2:10 p.m., Dobson entered the river alone for a swim while his friends remained on the bank. Within moments of entering the water, Dobson cried out for help. His companions rushed to the water's edge to find him engaged in a desperate struggle with a large shark. The animal was clearly visible as it repeatedly threw itself out of the water in aggressive attacks. The water around Dobson quickly became stained with blood as the shark continued its assault. Despite catastrophic injuries, Dobson fought to reach shallow water. His companions waded in to assist him, and together they managed to drag him onto the bank. The injuries he sustained were extensive and fatal: his right forearm was severed, with a deep wound at the elbow; his abdomen bore shark teeth marks with soft tissue torn away from his ribs to his chest on the right side; his left ankle was fractured with a large associated wound; and his right foot was severely bitten. William Joseph Dobson died within minutes of being removed from the water. Medical examination was conducted by Dr. Arthur Palmer. The attack is believed to have involved a bull shark, though the species was not definitively confirmed at the time. This incident remains one of the documented fatal shark attacks in New South Wales waters during the early 20th century.
