AI-generated summary

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.

Contributing factors

  • intoxication from alcohol consumption
  • rough sea conditions during return journey
  • inadequate crew supervision of passengers
  • failure to conduct proper final headcount upon return
  • absence of lifejacket
  • low railings on vessel
  • passengers sitting on esky near edge of boat
  • loud noise from engines and music preventing communication
  • distraction of crew and passengers by other falling passengers

Coroner's recommendations

  1. 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
  2. Operators of small charter vessels should incorporate mandatory multiple headcounts into their Safety Management Systems as part of risk assessment processes
  3. Crew should conduct proper final headcount before passengers disembark to detect missing persons immediately
  4. Charter operators should provide safety briefings before return journeys advising passengers of expected conditions and requirement to remain seated
  5. Crew should maintain proper supervision of intoxicated passengers during rough sea conditions, remaining on deck to monitor passenger safety
  6. Organisers of group events on charter boats should consider implementing buddy systems to ensure all participants are accounted for
  7. Public education campaigns should emphasise the significantly increased survival chances when wearing lifejackets in open water, as the Department of Transport currently promotes
  8. AMSA should maintain clear compliance presence with focus on headcount procedures for high-risk charter operators conducting regular reviews of safety standards
