Firefighters Race to Contain Kerry Ridge Bushfire North of Sydney

Firefighters battled to contain the Kerry Ridge bushfire burning in Wollemi National Park north of Sydney on December 10.

The New South Wales Rural Fire Service issued a ‘watch and act’ alert for the fire as it spread on the Tuesday. The blaze has burned through 53,000 hectares and is one of several bushfires alight in national parks surrounding Sydney.

The Kerry Ridge fire neighbours the giant Gospers Mountain fire, which has spread through nearly 320,000 hectares in and around the national park.

Smoke from the bushfires also brought thick smoke and hazardous air conditions to Sydney on December 10.
