Lilliane Brady, the longest-serving female mayor in NSW, will be honoured with a state funeral in her central western home town of Cobar.
Councillor Brady, who was considered a local legend in Cobar, served her community as mayor for more than 20 years until her death on Sunday at the age of 90.
She was due to retire in September.
The NSW Government announced on Wednesday a state funeral would be held in Cobar on February 19 "to honour the extraordinary lifetime of service".
"Councillor Brady was a strong advocate for western NSW and was first elected to the Cobar Shire Council in 1974, after moving from Sydney to the western NSW town in the 1960s," a statement said.
Councillor Brady was awarded a Centenary Medal in 2001 for services to local government and a Medal of the Order of Australia in 2012 for service to local government and to the community of Cobar.
In 2018 she was recognised with a Local Government NSW Lifetime Achievement Award.
Last year she was awarded the Minister for Local Government Award for her commitment to increasing participation of women in local government.
