Marina Morgan, 29, and her new husband Robbie were on a dream holiday when their buggy overturned while trying to do a U-turn on June 20.
Morgan, who was driving, was uninjured but his new wife died at the scene.
The accident took place on Whitsunday Boulevard at the northern end of Hamilton Island, Queensland, Australia.
A doctor, an off-duty dentist and an off-duty firefighter all desperately tried to save her, performing 35 minutes of CPR, but nothing could be done.
The couple, from Strathfield in Sydney, had got married just 10 days previously.
“It was just a tragic accident with a golf buggy,” he said.
“There may have been some inexperience driving those type of vehicles while turning it has rolled on its side and the woman has fallen out and sustained life-threatening injuries.”
“It just appears inexperience in driving that type of vehicle, turned too quick and rolled on its side and unfortunately, it has ended up with this result.”
Inspector Cowan confirmed the woman was not wearing a seat belt at the time of the accident.
“It appears there was no seatbelt worn at this point in time; we come back to the Fatal Five but now is not the time to dwell on what they should have done.”
Inspector Cowan, confirmed Robbie did perform a U-turn, and that he may have performed the move because the vehicle’s battery was running low and he wanted to return to a charging point.
“While turning around the buggy went on its side. No collision, no other vehicles involved and no indication of dangerous driving or alcohol,” he said.
