The fires, which broke out on Thursday, are raging at Toogoolawah and Mount Beppo, near the Brisbane Valley Highway, and Angledale Lane towards the Somerset Dam region.
Firefighters have urged resident to evacuate or enact survival plans.
The Queensland Fire and Emergency Service (QFES) warned crews may not be able to protect every property as the fires spiralled out of control.
Cattle have been seen fleeing the blaze, and it is feared some livestock will be lost.
As conditions worsened on Thursday night, QFES told residents to evacuate before it’s too late.
QFES said in a statement: “Fire crews are working to contain the fire but firefighters may not be able to protect every property. You should not expect a firefighter at your door.
«Crews will be conducting extensive backburning operations throughout the night and request the public avoid the area where possible to ensure their own safety and the safety of crews.»
QFES added: “Residents may be affected by smoke and are advised to close windows and doors, and keep respiratory medication close by if needed.
“Smoke may decrease visibility on roads so motorists are advised to drive with caution and to conditions.”
Residents in the area are being urged to follow this advice, issued by the QFES:
• Listen to your local radio station or visit the Rural Fire Service (RFS) website for regular updates.
• If you have a bushfire survival plan, finalise it now so you are ready to follow it.
• If you do not have a bushfire survival plan, or if your plan is to leave, identify where you will go if you leave the area.
• Advise family and friends of your plan.
• Close windows and doors to minimise smoke exposure.
• If you suffer from a respiratory condition, keep your medication close by.
• Drive with caution in low visibility conditions.
• Contact your neighbours to see if they need help preparing for the bushfire.
• Pack important documents and essential items (e.g., passports, birth certificates, prescription medication, food and water, and protective clothing) in case you need to leave the area.
• Put on protective clothing (eg, a long-sleeved cotton shirt, boots with thick soles).
• Drink plenty of water to stay hydrated.
• Bring pets inside; restrain them with a leash, a cage, or inside a secure room; and provide them with plenty of water.
• Take action to protect your livestock.
• Move flammable materials such as doormats, wheelie bins, and outdoor furniture away from your house.
• Fill containers such as your bath, sinks, and buckets with water so you have access to drinking water and firefighting water.
• Close windows and doors, sealing the gaps under doors and screens with wet towels to keep smoke out of the house.
