UPDATE: EIGHT homes and up to 1000 livestock are now believed to have be lost following a grassfire in Victoria's central west.
The lossese are expected to climb as emergency services continue mopping up after the blaze.
A Country Fire Authority (CFA) spokesman said police had confirmed that the number of homes destroyed by the 1150-hectare blaze had doubled from four to eight), including the 120-year-old Carngham Station homestead.

The number of livestock lost was between 600 and 1000, but losses could increase as emergency services continue assessing damage after the blaze, which saw the farming community of Carngham evacuated yesterday.
The CFA spokesman said two hay sheds had also been confirmed as destroyed as well as 12 pieces of farming machinery.
CFA operations officer Ian Morley said a farmer's ute being used for harvesting operations in a paddock was believed to have sparked the blaze, which was brought under control on Tuesday night, allowing residents to return to their homes.
Investigations were continuing, but the cause was believed to be accidental, he said.
Mr Morley said cooler conditions today had brought relief to firefighters who would work through the day to build mineral earth breaks to fully contain the fire ahead of warmer temperatures forecast for Friday.
At least six people, including a Carngham father and son who suffered radiation burns to their face and hands, were admitted to the Ballarat Base Hospital for treatment.
A 6651-hectare bushfire at Kentbruck in Victoria's far southwest continues to burn, but is not threatening any communities.
The CFA said light rains overnight allowed firefighters to take a well-deserved break from fighting the blaze, which started in pine plantation on Friday.
They will resume backburning today in anticipation of wind changes and pending warmer temperatures, a spokeswoman said.
