Police were unable to locate any witnesses to Miss Wilson's last movements but Coroner Cana na Nagara considered it most likely she had been walking her dog along the boardwalk, or grass verge that separated the boardwalk from the steep bank of medium to large sized rocks.
"For some reason Miss Wilson left the boardwalk and grass verge, and either stood at the edge of the band of rocks, or made her way down it."
"Then, whether as a result of feeling dizzy, fatigued or having a cramp in her leg, she slipped or lost her balance and fell head first between the rocks, and a large limestone rock rolled onto her chest and restricted her ability to breathe."
Miss Wilson's dog, named Louis, was running loose in the area and eventually alerted a passing pedestrian who, reaching the edge of the rocks, saw Miss Wilson's legs and initially thought she was lying on the rocks.
However drawing closer he saw a large rock was pinned to her chest; her body upside down with her legs higher than her head.
He tried to move the rock but was unsuccessful so returned to the walkway to call emergency services.
While waiting for them to arrive he flagged down four other passers by who returned to Miss Wilson and managed to remove the rock so that it was not resting on her.
"They checked Miss Wilson, and all agreed that she had passed away. This was confirmed by Emergency Services staff on their arrival."
Miss Wilson's cell phone, keys and a plastic toy used for throwing balls for dogs were found directly underneath her.
Following a post mortem examination it was confirmed by Dr Kate White that the cause of death was traumatic asphyxiation.
The findings concluded her death was a result of an accident and was satisfied there were no suspicious circumstances.
Coroner Cana na Nagara extended her heartfelt sympathies to Miss Wilson's family and friends for their loss.
