At around 6.45pm on Monday evening, fire brigades from Caldwell, Bunnaloo and Tantonan were called to a haystack fire on Caldwell Line Road.

When they arrived, a haystack containing 800 bales of export oaten hay was fully alight.

Crews quickly jumped into action, unable to save the stack, but instead protect other surrounding stacks, a hayshed and a nearby crop.

With the fire doused and protective measures in place, brigades returned to base.

However, the next morning the same brigades received an emergency call to the same property.

The hayshed, which contained the same hay, had self-combust and was in danger of spreading to haystacks and surrounding crops.

Brigades implemented earth breaks and other protective measures whilst extinguishing the shed.

Thankfully, there was no further escape.

Firies are, and will continue to, monitor the property with fingers crossed there are no more incidents of self-combustion.

RFS Mid-Murray Zone are pleading with farmers to check their hay's moisture content as a southerly wind change is set to sweep in on Thursday, bringing with it, a possible lightning storm to top it off.
