Victoria Police’s chief commissioner Mike Bush has re-asserted his vow that his force will not give up until fugitive and suspected murderer Dezi Freeman is found.

Commissioner Bush was among a large contingent at last Monday’s National Police Remembrance Day service in Melbourne, where he paid homage to the 178 officers who have died at work in the force’s history.

A service was held at the police command centre at Ovens, which continues to coordinate Australia’s largest manhunt for Freeman.

The two officers he allegedly shot and killed at his Porepunkah property on 26 August - Detective Leading Senior Constable Neal Thompson and Senior Constable Vadim de Waart-Hottart - were a significant focus for the force at local services.

Commissioner Bush said the search for Freeman is ongoing, with around 40 square kilometres of bushland searched since the armed fugitive disappeared into land adjoining Mount Buffalo National Park - which remains closed to the public.

Commissioner Bush said more than 200 officers remain involved in the ongoing search, which entered its sixth week on Tuesday.

“At the height we had nearly 500 officers up there conducting the search, investigating and providing reassurance to the community,” he said.

The large-scale search has received assistance from multiple interstate, national and international authorities.

Commissioner Bush said the public had provided around 1400 pieces of information to police.

“None of them have led to any positive leads, but we explore them all,” he said.

A $1 million reward remains on offer for information leading to Freeman’s arrest.

Previous travel restrictions through Porepunkah were lifted two weeks ago and visitors have started to slowly filter back into the area.

A Victoria Police spokesperson said restrictions were constantly being assessed.

Police advise that if you see Freeman, call 000 immediately but do not approach him as he was still considered heavily armed and dangerous.

Anyone with other information is urged to contact Crime Stoppers on 1800 333 000, submit a confidential report online at www.crimestoppersvic.com.au or visit your local police station.
