Ross Streeter yesterday pleaded guilty to murdering his father and uncle on their remote sheep farm near Avoca earlier this year.
The 31-year-old Bendigo man had originally denied killing the brothers at the Natte Yallock farm house on March 14.
Streeter made a brief appearance in the Victorian Supreme Court where he entered the change of plea.
Streeter, the son of Douglas and nephew of John, was arrested in Avoca just metres from his father’s house on March 16 after a police investigation discovered the connection.
He was charged with two counts of murder.
The Melbourne Magistrates Court previously heard Streeter went to the family farm on March 14 and shot his uncle John.
He then left and went back to Bendigo, but returned later and shot his father Doug, the court heard.
Both men, aged in their 60s, were found dead by Doug’s wife just before 6pm.
The discovery of John Streeter’s wallet at a recycling plant in Bendigo the day after the murder led police to the son, who regularly helped his father and uncle on the merino sheep farm.
The wallet was believed to have been taken from the victim after the murder and dumped in a bin somewhere between the crime scene and the Bendigo area.
Before his arrest, an extensive police search of the 1600-hectare property north-east of Avoca discovered the gun believed to have been used in the double killing.
Taken to the Royal Melbourne Hospital after his arrest for treatment to non-life threatening, self-inflicted injuries, Streeter later made no comment when interviewed by police over the murders.
Streeter will appear in court again on December 2.
