The wife of Dezi Freeman has urged her husband to surrender as the manhunt continues for the accused double cop killer.
Freeman, 56, fled into the bush on Tuesday following a deadly ambush at his property in Porepunkah, about 300km north-east of Melbourne.
Amalia Freeman, 42, released a statement via lawyers on Sunday urging her partner to turn himself in.
She also shared her condolence for the families of the two slain cops Detective Leading Senior Constable Neal Thompson and Senior Constable Vadim De Waart.
'We echo the requests of the Victoria Police for the swift and safe conclusion of this tragedy,' Ms Freeman said.
'I lend my full support to Victoria Police in their search for my husband and will co-operate with Victoria Police in any way that I can.
'Please Dezi, if you see or hear this, call 000 and arrange a surrender plan with the police.'
Tough conditions have impacted search efforts in recent days with thunderstorms, lashings of rain and hail battering the rural town.
Temperatures plunged below 6C early Saturday, with wind gusts of more than 60km/h in Porepunkah after blizzard-like conditions.
Snow was predicted down to levels of 700m.
More than 450 police officers have been deployed to Porepunkah as part of the search, which has included examining disused mines, caves, and dugouts in and around the rural community.
Victoria Police issued a statement on Saturday afternoon to announce the relocation of its forward command post from Feathertop Winery just outside Porepunkah to a government office in the town of Ovens, about 12km away.
'The new site is a fit-for-purpose facility and will best support Victoria Police's operational activity moving forward,' the statement said.
'We would like to reassure the community that police are not leaving the area.'
Freeman's wife and 15-year-old son were arrested on Thursday night following an operation at an address in Porepunkah before they were interviewed and released, pending further inquiries.
'There may or may not be charges that follow,' Victoria Police Chief Commissioner Mike Bush said.
Police helicopters and drones have been circling the area for days in the hope of catching a sign of the fugitive's whereabouts.
Freeman, who has bush survival experience, was last seen in dark green tracksuit pants, a dark green rain jacket, Blundstone boots and reading glasses.
Meanwhile Detective Thompson and Sen Const De Waart will be farewelled with full police honours next week at Melbourne's Victoria Police Academy in Glen Waverley.
Senior Constable De Waart's service will take place on September 5.
Detective Thompson will be farewelled on September 8.
The pair were killed while serving a warrant on Freeman for alleged child sex offences.
A third officer who was shot in the thigh remains in hospital.
Players, umpires and officials from local sporting associations wore blue arm bands during this weekend’s finals in honour of the two fallen officers.
