On 29 January, over 500 firemen fought the two fires at Delburn which had joined together into one big fire. The fires had burnt near Boolarra and Darlimurra, south of the city of Morwell. No buildings were burnt. A cool change in the weather on 30 January made it easier to fight the fires, but also made it windy, which led to spot fires (new, small fires from burning plants blown ahead). On the evening of 31 January, fire crews worked to stop the fire spreading to the north. They fought to protect the main power transmission lines taking electricity to Melbourne from the Latrobe Valley. The fire was also close to the Hazelwood Power Station, Victoria.
