Seven people - including four children - have died in Western Australia in what police are describing as a "mass tragedy". 

The Western Australia police commissioner Chris Dawson confirmed that four children and three adults have been killed in a suspected mass shooting in the southwest of the state, 9 News reported. 

Police were called to the scene of an Osmington property at 5:15am (local time) Friday morning.

"Police are currently responding to what I can only describe as an horrific incident in Osmington, 20km north-east of Margaret River," the police commissioner said. 

"It is early in this investigation. Based on what we do know, this is clearly a tragedy."

"At about 5.15am this morning, police were called to a rural property on the outskirts of this property at Margaret River."

Mr Dawson said the bodies discovered at the scene had "gunshot wounds" and firearms were found at the scene. 

Police are not looking for a suspect, Mr Dawson said. 

"We don't have any information to raise further public concern about that element."

None of the victims have been identified yet. Mr Dawson said the police are "trying to locate other members of the family and friends."
