Victorian authorities confirmed they received reports of property losses from a fire near Ouyen, in the far northwest of the state, on Sunday night.

"Our thoughts are with the community around Hattah in the northwest of the state," she told reporters in Melbourne's west on Monday.
State Control Centre spokesman Luke Heagerty said wind blowing in contrasting directions caused the fire to break its containment lines.Â
"A couple of breakaways have been able to run freely through the national park itself but once it's reached the private property, we've been able to slow it down," he told AAP.
The Little Desert fire covers 84,000 hectares, while dual fires burning in the Grampians total 46,000 hectares.
