"Property [is] currently being protected in Da Gama Park [and] evacuation taking place at the Military Flats for safety," Liezl Moodie said.
The wildfire started burning on Wednesday morning on the slopes of the mountain.
According to Moodie, the blaze was inaccessible to firefighters as it was too high up on the mountain.
Two helicopters were on the scene to water bomb the inaccessible areas.
No injuries have been reported.
