Tragedy in Margaret River

Major Crime officers are en route to the crime scene

An emergency call was made to police around 5.15am by a man at the home, and Police say that call lasted around two minutes.

When police arrived on the Osmington property, they discovered all seven people had died of gunshot wounds.

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.

Mr Cockman said he would never forgot his children's personalities.

"I have lived in the Margaret River area all my life and welcome all enquiries".

"Four young children, [a] mother and a grandmother being killed in this way is just a terribly distressing and sad thing, and I think we all feel it keenly", he said.

"Police do not believe any other person is involved with these crimes", he told reporters.

"We are treating this as a matter in which clearly six persons are the subject of a homicide crime scene".

Police would not comment on the possibility of murder-suicide, but said they are not looking for a suspect.

"Small rural communities are very tight-knit, this will have mental health consequences and I would encourage anyone who feels they need help to seek it from their GP", Dr Gannon said.

The WA premier was on Sunday questioned about "nasty comments" since made overseas, including from the USA, that question whether Australia still remains an example of "excellent" gun control after the mass shooting.

Cynda Miles worked for a local community group, according to neighbours and public records.

Detectives are expected to spend several days at the property. The family were well known and well liked in their community.

She described the family as "lovely people".

Margaret River's main street, a cafe worker said, "they have got it wrong".

One woman was located inside the family's home and five people - including a woman and all the children - were found in a "converted shed structure", Dawson confirmed.

While the Margaret River community is resoundingly resilient and pro-active in this arena, and vital support mechanisms for the family members directly affectedhave been swiftly put in place, it is now apparent that no one was able to reach in to the core of this family's private pain. "How the hell Peter did that I still can't figure out, but if someone did it ... he did a good job, he did a really good job".

Speaking outside the Margaret River police station Cockman said he felt "tremendous sadness" over the death of his children.

Despite all of that resentment and anguish, he says he still loves Cynda too.
