A six-year-old boy is among two people dead after a fire razed a home in regional Victoria.
The child and a 33-year-old man died at the Cunninghams Road in Tyaak property, after fire engulfed the house about 11.40pm on Saturday.
A 34-year-old man was taken to hospital and remains in a critical condition, police said on Sunday.
Police believe 13 people were staying at the holiday property and a number of people were taken to hospital with injuries.
Three adults went to hospital in a serious condition and one was in a stable condition, Ambulance Victoria said.
Four children were also taken to hospital with serious conditions.
It is understood some other people were assessed at the scene.
Sixteen CFA units were sent to the property, with a number of other support vehicles. Police, SES and Ambulance Victoria were on also scene.
"It took approximately an hour and a half to get the fire under control,” CFA commander Charles Cleary said.
Seymour Sergeant Daniel Raynor says the Arson and Explosives Squad is investigating the cause of the deadly blaze.
"Detectives are still speaking to those family members (in hospital) to try to ascertain the exact occurrences," he told reporters in Tyaak.
"Obviously given the extremely tragic circumstances and the situation that we now have, those conversations and those investigations, I dare say, will be ongoing for some time."
