A large "dangerous and uncontrolled" bushfire is threatening lives and homes in far north Queensland, with residents told to leave immediately.
The Queensland Fire and Emergency Services is fighting a blaze travelling on both sides of Oakey Creek Road in Cooktown, north of Cairns.
Conditions are very dangerous and firefighters may soon be unable to prevent the fire advancing, the 'leave immediately' alert issue warns.
"The fire poses a threat to all lives directly in its path," it says.
"You should not expect a firefighter at your door: act now."
QFES says the fire is expected to reach multiple properties and have a significant impact on the community.
Power, water and mobile phone service may be lost and road conditions may become very dangerous over the next several hours.
People in the area will be affected by smoke, which will reduce visibility and air quality.
