Thousands of firefighters continue to battle bushfires across five states and territories, with blazes threatening homes and scorching hundreds of thousands of hectares of bushland.
NSW is under the worst threat with more than 90 fires that have burned more than 350,000ha.
Seven of those fires continue to burn out of control.
A 9800ha blaze near Cooma threatened 15 homes on Saturday as more than 100 firefighters worked to contain the inferno.
Crews are battling two other major fires near Yass and Sussex Inlet that have threatened homes but eased thanks to cooler weather conditions.
Firefighting crews in Tasmania, Victoria, Queensland and the ACT also fought blazes on Saturday.
Authorities in Tasmania issued a watch and act alert as a bushfire between Forcett and the Tasman Peninsula strengthened.
The Tasmanian Fire Service (TFS) issued the alert on Saturday for communities near the blaze, noting increasing activity on the fire's boundary in the Kellevie, Bream Creek and Marion Bay areas.
TFS senior station officer Phil Douglas said the fire had expanded to cover 23,600 hectares, and fire crews were back-burning to contain the blaze.
Tasmanian emergency services have been fighting fires since January 4.
Several fires were burning across Victoria but they were under control, including a blaze at Kentbruck in the state's southwest, where 66 fire crews remained stationed.
A State Control Centre spokeswoman said the Kentbruck blaze had increased to 11,890 hectares, due to backburning as part of containment efforts.
A 13-hectare blaze at Kangaroo Ground on Melbourne's outskirts had been declared safe despite going close to a number of properties.
In Queensland, there were 34 bushfires across the state but none threatened homes.
Volunteer crews were using earth moving equipment to contain a fire in bush near Undullah south of Brisbane.
Firefighters continue to monitor three fires sparked by lightning strikes on Thursday, west of Gympie.
Two small grassfires were the only blazes in the ACT on an extreme fire danger day.
Both, one at Hall and the other at Kambah, were extinguished, the ACT Emergency Services Agency (ESA) said.
A milder weather forecast allowed ACT authorities to end the total fire ban across the territory on Saturday night.
