State and federal leaders of government have shown their support for the local community, police force and emergency services following the Porepunkah shooting on Tuesday.

Suspected gunman Dezi Freeman, 56, remains on the run in the bush after he allegedly killed two police officers, Detective Leading Senior Constable Neal Thompson, 59, and Senior Constable Vadim De Waart, 35, and seriously injured another during a warrant search of his rural property on Rayner Track.

National coverage of the event has shown the impact felt far and wide, but particularly the local close-knit Alpine Shire and North East community.

Ovens Valley MP Tim McCurdy said the heartbreaking events which unfolded on Tuesday morning were beyond comprehension.

"The senseless and unimaginable loss of two dedicated police officers, along with another officer seriously wounded, is a tragedy that has shaken our entire community to its core," he said.

"I extend my deepest condolences to the families, friends and colleagues of the officers whose lives have been so cruelly taken.

"This is a dark day for Victoria Police, for our region, and for the whole of Victoria."

Mr McCurdy said on Tuesday we were reminded of both the fragility of life and the extraordinary courage of our police.

"Our community will stand united in mourning and in support of those who dedicate their lives to keeping us safe," he said.

Federal MP for Indi Helen Haines said the tragedy marked the most terrible of days for the community.

"This appalling event has shaken not only Porepunkah, but communities right across the North East, and indeed the nation," she said.

"While we may be geographically spread, we are close-knit, and in moments like this we feel the loss together.

"I want to acknowledge and thank the police and emergency services who are continuing to respond to this ongoing incident.

"I also thank the local community for their cooperation during the police response; in particular, the principal and staff of Porepunkah Primary School, who kept their students safe and calm during lockdown for many hours.

"As this is an ongoing situation I urge members of our community to pay attention to and follow the information and instructions provided by Victoria Police."

Dr Haines shared her condolences to the families of Det Led Sen Const Thompson and Sen Const De Waart.

"The hearts of the families of Detective Leading Constable Thompson and Senior Constable De Waart will be forever broken," she said.

"Their lives have been shattered, and they remain foremost in our thoughts as they face this tragedy and the unimaginable circumstances of their loss.

"We continue to pray for the recovery and healing of the officer who was injured in the line of duty, and for others at the scene whose mental trauma cannot be underestimated or ignored."

Victorian Premier Jacinta Allan said the government stood with Victoria Police every day they wear the uniform with pride.

"What has occurred in Porepunkah is shocking and utterly heartbreaking," she said.

"We stand with the community of Porepunkah – who are now carrying the weight of this horrific day… they will not carry that weight alone.

"Our thoughts are with the emergency services still responding to this unthinkable crime and our hearts are with the families, friends and colleagues of those who have been lost."

Prime Minister Anthony Albanese also responded to the shooting on Tuesday.

"Our thoughts are with the police for the work that they do each and every day," he said.

"The men and women who wear our uniform, wear the uniform of the police force take risks each and every day."

Victoria Police Chief Commissioner Mike Bush said on Wednesday morning the force had been overwhelmed with messages from across the country and beyond standing in solidarity with police.

"It's very comforting to know the public support our police," he said.

"All of my commissioner colleagues across the country and across the ditch have sent messages of support."
