A large fire could hit the Maryland area of Queensland and Cullendore, in NSW, by 10.45pm (AEST) on Wednesday, authorities say.
A large, uncontained fire is burning towards two communities on the NSW-Queensland border, and authorities are urging residents to evacuate.
People living around Maryland, in southern Queensland, and Cullendore, NSW, are being told to finalise their bushfire plans or leave their homes.
The Queensland Fire and Rescue Service (QFRS) says the blaze, which is burning near the Mt Linsday Highway and moving northeast, could hit both communities by about 10.45pm (AEST) on Wednesday.
Fourteen fire crews are working to contain the blaze, but firefighters say they may not be able to protect every affected property.
