Families are taking shelter at an evacuation centre in Sydney's southwest as an out-of-control bushfire continues to burn.
More than 140 fire fighters are battling the blaze in Wattle Grove as around 200 evacuated residents wait in safety at Moorebank Sporting Complex, including many families with young children and some with pets in tow.
A NSW Rural Fire Service emergency warning was first issued after 3.30pm on Saturday for the fast-moving bushfire, with residents in the Wattle Grove community and Holsworthy military complex told to shelter in place.
Residents in Voyager Point, Pleasure Point and Sandy Point are being advised by the NSW RFS to leave south towards Heathcote and to not travel west.
The cause of the fire is unknown and fire fighters are conducting backburning to contain the blaze.
Heathcote Road has been closed and buses are replacing trains between East Hills and Glenfied on the T8 airport and south line, with the Transport Management Centre telling people to allow plenty of additional travel time and to check indicator boards.
There are no reports of homes being damaged by the blaze, a NSW RFS spokesman said.
