A man who murdered his partner and his two children has been increased to a minimum prison term of 36 years, but relatives of the victims say that the sentence will never be enough.

Steven Graham Peet pleaded guilty to the 2016 assassinations of Adeline Yvette Wilson-Rigney and her children Amber, 6, and Korey, 5, on a property north of Adelaide.

He received a mandatory life sentence in prison and the Supreme Court imposed a period of 30 years without parole.

But after the Crown argued that it was inadequate, the Criminal Court of Appeals extended it for six years.

Steve Egberts, the grandfather of Korey and Amber, says he is still upset when describing the phrase as manifestly inadequate and out of step with public opinion.

"I do not think this is enough for what he did to those little children," Egberts told reporters.

& # 39; The way he killed those children is beyond comprehension. There are three murders in cold blood.

"This was more than horrible what he did to those children."

The bodies of Mrs. Wilson-Rigney and the children were found with cable ties around the neck and hidden under clothing and bedding and, in the case of the child, under a tent for children's games.

Looking for a longer term in prison, Public Prosecutor Adam Kimber said Peet had taken the time to consider his own interests between the murder of his partner and the murders of the two children.

After killing his mother, the court learned that Peet had made the children eat breakfast, allowed them to watch television and went out to smoke a cigarette.

"When faced with the possibility of discovery, he chose to kill," Kimber said.

But defense attorney Bill Boucaut said Peet's guilty plea indicated a deep sense of pain and regret for what he had done.

In his reasons for increasing Peet's term of imprisonment, Chief Justice Chris Kourakis, Judge Sam Doyle and Judge Martin Hinton said that the starting point for the minimum period should be 39 years with the right of 33 years. at some discount for your guilty pleas.

But they said that reducing it below 36 would not "justify the dignity of the victims."

"It is true that it is very far away, but three people, including two very young children, were killed."
