Extreme weather conditions saw the Black Summer fires devastate 79 per cent of the shire's landscape, with the loss of three lives and more than 500 homes destroyed.

Mayor Liz Innes said the coming weeks will be tough for many in the community after a traumatic year.

"We have certainly been tested this year, but this community has shown its strength and it's lovely to see a quiet optimism starting to shine through," she said.

"I don't underestimate the reality of our situation, however."

Cr Innes said Eurobodalla's Bushfire Recovery Service case managers were supporting hundreds of local people.

"There are still people doing it very tough and they must be our priority. The anniversary will be particularly difficult for some of our residents."

Cr Innes will unveil a plaque on December 9 in a small ceremony on the Council Chambers forecourt to commemorate the first anniversary.

"At this time of reflection, there is also gratitude. We thank the firefighters and emergency workers who protected us, and we honour the courage of so many residents who worked together to provide safety and comfort in those dark days," she said.

The council's flags will fly at half-mast again on March 4, 2021, signaling fires declared out in Eurobodalla.

For support, contact Eurobodalla's Bushfire Recovery Service, open 9am to 4pm Monday to Friday.
