Firefighters are currently battling a bushfire near suburban homes in Sydney’s southwest.

Fire and Rescue NSW were alerted to the blaze at Revesby Heights at around 1:20PM.

“We found an area of bush alight behind a row of houses,” Fire and Rescue NSW Superintendent Scott Dodson said.

More than 20 firefighters were on the scene this afternoon as the situation was upgraded to a two-alarm fire.

Four fire trucks were on the scene and a water bombing aircraft has been put on standby.

A statement on the Fire and Rescue website reads that no houses are currently under immediate threat, however there are concerns that winds are continuing to increase.

More to come.
