West Australian Police Commissioner Chris Dawson says officers were called to the property at Osmington, northeast of Margaret River, about 5.15am on Friday.

“Police are currently responding to what I can only describe as a horrific incident,” he told reporters in Perth.

“This is a significant tragedy.”

Dawson would not confirm if it was a murder-suicide.

“It’s not appropriate for me to speculate on any further matters,” he said.

“I can only say at this point in time we have no information to raise concern about wider public safety issues.”

Dawson said the bodies of two adults were found outside near a building, while five were discovered inside. He said they appeared to be residents.

Two firearms were found at the scene, and victims suffered gunshot wounds.

“It appears that gunshot wounds are there but I don’t want to go further than that,” Dawson said.

“We are trying to locate other members of the family and friends.

“I’m not in a position to release any further details of the identity of the deceased.”

Perth homicide detectives are helping local police in the investigation and are expected to remain at the property for several days.

A police chaplain is there to support officers.

“Regrettably, these tragedies do take their toll,” Dawson said.

He said the small Osmington community would be reeling but was confident it would rally together.

“This devastating tragedy will no doubt have a lasting impact on the families concerned, the whole community, and in particular, the local communities in our South West.

“Naturally, we will be asking for anyone who does know anything about this matter to contact police.”

Osmington only consists of a handful of roads, farms, vineyards, holiday chalets and a small Anglican church.
