The grieving father of four children killed in a mass murder-suicide in Western Australia says he still loves the man suspected of taking their lives.

Aaron Cockman broke his silence on Sunday, telling the media he feels "tremendous sadness" for his children but isn't angry at their grandfather Peter Miles.

Cockman found comfort in the fact all his children "died peacefully" in their beds on Friday.

"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," he said.

"I don't feel angry ... Peter's an awesome man."

Cockman's daughter Taye, 13, and sons Rylan, 12, Arye, 10, and Kadyn, 8, were all found dead inside a property in Osmington, northeast of Margaret River. Katrina, the children's mother, and her parents Cynda and Peter were also found dead at the scene.

Cockman's youngest son Kadyn was in his mother's bed and was found dead with her.

Three firearms have been seized from the property, all belonging to Peter Miles. Police are treating the incident as a murder-suicide and aren't looking for any further suspects.

Cockman said he believed the murders were premeditated.

"Peter didn't snap, he thought this through," Cockman said.

"I still love who Peter was. If it wasn't for him, I wouldn't have Katrina, I wouldn't have her kids."

Cockman said while he felt deep sadness for his children,  he didn't want anyone to feel anger about the situation.

"So it's not some random guy off the street who's taken them away from me -- he gave them to me and now he's taken them away.

"If it had to happen, there is no better person than that."

Premier, Police Call The Incident A 'Tragedy'

Western Australian Premier Mark McGowan said this was one of the worst tragedies the state has seen.

"Can I especially commiserate with those people who have endured the unendurable," McGowan said at Osmington on Sunday.

WA Police said they received a call on Friday morning about 5.15am. When police arrived they found seven bodies -- two adults outside the property and the five remaining bodies inside the home.

The Osmington shooting is believed to be the biggest mass shooting since the 1996 Port Arthur massacre where Martin Bryant killed 35 people.

WA Police Commissioner Chris Dawson called the incident a "devastating tragedy".

"[It] will no doubt have a lasting impact on the families concerned, the whole community and, in particular, the local communities in our south-west," he said on Friday.

The local government has established sessions with psychiatrists at the Margaret River community resource centre which are available for members of the community. Mourners are also able to offer their condolences at the centre.
