Australian police have named the suspect in the fatal shooting of two police officers in the Australia Alps as Dezi Freeman.

On Wednesday morning, Victoria Police said the 56-year-old is heavily armed and "still at large", almost 24 hours after officers tried to execute a warrant at his rural property and were fired upon.

"We are pouring every resource into the search for this person", Chief Commissioner of Victoria Police Mike Bush said.

He said this is "not a hostage situation" - addressing previous reports by local media - and said that Mr Freeman's partner and children are safe.
