Country Fire Authority district 17 operations manager Dale Russell said crews were called to Wawunna Road, Horsham, at 9.26pm.

He said there were three small fires that started near the railway line underpass.

“The total area of the three fires was about a hectare,” he said.

“The cause was illegal fireworks, so police are now investigating the incident.”

Mr Russell said crews were able to get the fires under control fairly quickly. 

Firefighters also attended a small blaze at Noradjuha on Sunday.

Mr Russell said the fire was near the town’s recreation reserve and crews were able to contain it quickly.
