Firefighters are battling three concerning blazes in Tasmania with aircraft water carriers called in to assist.
Around 80 firefighters are trying to bring fires at Lanes Tier, Bradys Lake and Mentmore Tier in the state's central highlands under control.
Emergency crews are being supported by 12 aircraft and 10 machinery assets to help control the fires that have burnt approximately 5000 hectares.
"To date there has been no further property losses," incident controller Mark Klop said.
"We are prioritising our response in areas where there are houses and other assets."
Crews are particularly concerned about the Lanes Tier fire which has the potential to expand and impact properties.
"The fires remain active and a change in weather conditions could put properties at risk and make roads unsafe, people in the area must take action to protect themselves and their families," Mr Klop said.
"We are urging people to be aware of the conditions and monitor for updates on warnings at TasAlert."
Police are working to determine the cause of the fires and suspect two of the five which started on Wednesday were deliberately lit.
Locals are being urged to report anything suspicious in the area to authorities.
