Police are investigating the deaths of a man and an infant at a tourist attraction in Williamstown, South Australia.
Emergency services were called to a "serious incident" at around 4.30pm involving a man and a baby girl at the The Whispering Wall, which is located in the Barossa Reservoir.
Police said emergency services were called after witnesses saw a man and infant go over the edge of the 36-metre high wall and fall to the ground.
On Wednesday night, SA Police confirmed in a statement both the baby and the man had died.
"When patrols arrived, they found a deceased man and an infant who was unresponsive. Paramedics worked on the infant but sadly, she died at the scene," police said.
"Detectives from Barossa CIB and Major Crime Branch, along with forensic crime scene investigators, have attended the scene to examine the circumstances surrounding the incident."
Police said a report is being prepared for the coroner and no one is being sought over the deaths.
The Whispering Wall is a popular tourist attraction known for its "unique acoustic effects".
"Words whispered at one side can be clearly heard at the other, more than 100 metres away," it says on South Australia's page on the Whispering Wall.
"Children in particular love visiting the wall and testing its abilities."
