The Carrum Downs fire has been brought under control, and the emergency warning has been downgraded from a 'Watch an Act' to an 'Advice'.

That advice is: "There is currently no threat to communities, but you should continue to stay informed and monitor conditions."

CFA crews have been winning the fight against the fire for some time, and when the cool change blew through the area about 7pm it did not set back the firefighting effort. People were already beginning to return to their homes at that time.
