Damien Mills, a 35-year-old mortgage broker, drowned in the Indian Ocean after falling off a charter boat returning from Rottnest Island on 31 October 2014. While intoxicated, he was likely knocked overboard during rough conditions near the Windmills area during the return journey. Despite passengers and crew observing rough seas and passengers falling, no one witnessed his fall. The critical failure was the absence of a proper final headcount upon returning to Fremantle Harbour at 4:00 pm—had his absence been detected immediately, rescue services would have had a 99.9% probability of finding him alive. The vessel operator conducted incomplete and potentially inaccurate headcounts without proper documentation. Improved maritime safety procedures, specifically mandatory multiple headcounts and proper crew supervision of intoxicated passengers in rough conditions, could have prevented this death.

Coroner's recommendations
AMSA to promote the conduct of multiple headcounts (at least two) for charter operations through industry committees, publications, safety awareness bulletins, and SMS workshops to ensure safety standards are maintained
Operators of small charter vessels should incorporate mandatory multiple headcounts into their Safety Management Systems as part of risk assessment processes
Crew should conduct proper final headcount before passengers disembark to detect missing persons immediately
Charter operators should provide safety briefings before return journeys advising passengers of expected conditions and requirement to remain seated
Crew should maintain proper supervision of intoxicated passengers during rough sea conditions, remaining on deck to monitor passenger safety
Organisers of group events on charter boats should consider implementing buddy systems to ensure all participants are accounted for
Public education campaigns should emphasise the significantly increased survival chances when wearing lifejackets in open water, as the Department of Transport currently promotes
AMSA should maintain clear compliance presence with focus on headcount procedures for high-risk charter operators conducting regular reviews of safety standards
