Heather Wilton says the past 12 months have been among the most challenging in her time with Greater Hume Council, ahead of her mayoral role coming up for election.
Councillors look set to re-elect Cr Wilton for a one-year term to see them through to the NSW local government elections in September, 2021.
In a report to Wednesday's meeting, the Holbrook resident said the drought, fires and now COVID-19 had been some of the most difficult times since her council experience began in 1987.
"For most of the residents of our great shire, many have experienced the worst of times beginning with the very dry season, with a hot early start to the devastating fire season," Cr Wilton said.
"No sooner had the fire and summer season calmed down, all of us were quickly coming to terms with the Coronavirus.
"I am very pleased to say, and want to congratulate and thank sincerely, all the hardworking volunteers within our council staff, who stepped up to confront the fire situation."
The mayor and deputy mayor elected on Wednesday will hold their office until the postponed ordinary elections are held on September 4, 2021.
Cr Doug Meyer said he would seek to remain the deputy mayor.

"We really believe we've done something over the past eight years, and if you drive around some of the towns, you'll see a marked difference," he said.
Cr Meyer said the Henty rail crossing and securing better water supply for residents were two unfinished projects he would pursue in the next 12 months.
At Greater Hume Council's request, there will be no by-election due to the resignation of Cr Denise Knight, who took part in her last meeting in August.
