Four people have died after a mid-air collision between two helicopters near Seaworld on Australia's Gold Coast.
Queensland Police say initial investigations suggest the crash happened as one aircraft was taking off and the other was landing.
Those who died were travelling in the same helicopter. Three other passengers are in a critical condition.
Five of the six people on the other aircraft, which made an emergency landing, suffered minor injuries.
The Australian Transport Safety Bureau (ATSB) is investigating the collision, which happened at about 14:00 local time (04:00 GMT).
The two aircraft came down near a tourist strip known as Main Beach, about 75km (47 miles) south of Brisbane.
Gary Worrell of the Queensland Police Service told reporters the four deaths and three serious injuries had all occurred in the same aircraft.
"It's a difficult scene," he said. "Due to the area it's located, on the sand bank, it was difficult to gain access, to get our emergency services to the scene to manage it appropriately."
