Emergency services earlier said the properties at Chisholm were "not actively under threat" despite their proximity to the blaze on Simpsons Hill, near Deacon Close and Enid Lorimer Circuit.

The fire moved east and was burning at a slow rate, but about an hour after being alerted at 6:45pm, firefighters had contained the blaze.

One firefighter was taken to Canberra Hospital with heat exhaustion.

The Bushfire Alert and Warning Level was set at "advice", signifying no immediate danger, as units on scene tried to control the fire which reached three hectares in size.

Fifteen crews later blacked out the fire and remained on scene patrolling the blaze.

Chisholm resident Kerry Rodway said the fire reached halfway down Simpsons Hill on one side, and was about 50 metres from the nearest house.

Her own home was 100 metres away from the blaze, or six houses from the property nearest the fire, but she decided to wait and see what happened before any thoughts of evacuating.

"I just worried about the embers when the wind was blowing this way, but it quickly turned around," she said.

"The wind was blowing towards our place at the time, and then started blowing from the east."

Other residents drove to her street to see the fire, she said.
