A family of seven including four children was found dead with gunshot wounds on Friday at a rural property in southwest Australia in what could be the country's worst mass shooting in 22 years, police and news media said.
Seven people who were killed in a suspected murder-suicide are all from the same family.
What they found was the bodies of two adults outside, and another adult and four children inside the converted shed.
Police are treating it as a murder-suicide and said they are not looking for any suspects. The bodies of Peter and Cynda Miles were found Friday at their farm in Osmington, near Margaret River, Wester Australia.
Commissioner Dawson wanted to "strongly emphasise that police do not believe any other person is involved in this crime".
The others are believed to be their 35-year-old daughter Katrina Miles and her four children - daughter Taye, 13, and sons Rylan, 12, Arye, 10, and Kadyn Cockman, eight.
"We will investigate this awful crime", said Dawson, noting that this event is "a bad tragedy".
Another local woman who was a friend of both Katrina Miles and Cynda Miles, who did not want to be named, described Katrina as a dedicated and attractive mother to her equally handsome children.
"I actually spoke to him the night before the incident", said Richard Dosser, who lives about two kilometres down the road.
In Osmington that in Western Australia, was discovered seven bodies, four of them children.
"What I will confirm is that at 05:15am yesterday morning, police received a triple zero emergency call from a male person", he said.
A neighbor, Meg Janes, told Perth Now she heard the gunshots and assumed someone was shooting kangaroos but said in hindsight it was likely something far more sinister.
There's an eerie feeling about the tourist town of Margaret River.
He said police thought the call was made from the property, but said it was a "complex criminal investigation".
He also said the father of the children has been contacted and that police were helping him during this hard time. They all resided at the property, he said.
Much tougher gun laws were enacted as a result of the horrific 1996 mass killing, as well as a near-ban on automatic and semiautomatic weapons.
"Cynda was a well-loved and very active member of our community. she had a deep commitment to the environment and she will be so sadly missed".
Red Cross counselling services remain available to the public at the Margaret River Community Centre, where friends have also been placing floral tributes.
