The Australian government's announced 3 thousand reserve troops will be deployed to help fight deadly bushfires, which are continuing to burn across the country.
The nation's prime minister says there's a risk they could escalate in three states.
Two more people have died and thousands of others are being evacuated.
Scott Morrison says hot and windy weather could lead to one of the worst days of the crisis.
He also confirmed the death toll had risen to 23 - with two more fatalities confirmed on Saturday - and warned "we are facing another extremely difficult next 24 hours".
"The priority of this deployment is to assist ensuring the safety of life, to support the evacuation of affected people, particularly in isolated communities and provide assistance to isolated communities and support state managed evacuation centres," he said.
Strong winds and high temperatures are expected to bring flames to more populated areas, including the suburbs of Sydney.
