The deputy mayor of a Victorian city has resigned due to bullying. 

Mildura Deputy Mayor Cyndi Power says she is choosing “health and sanity” over continuing in the position.

She resigned in a post on social media, saying “no position is worth your mental health”.

“Some may say I've let the bullies win, but I am choosing my health and sanity.”

Her councillor Facebook page has been taken down, and she has asked for privacy.

“This decision was not made lightly, and was made due to personal reasons,” she said.

“I thank the community members who elected me, my fellow councillors who supported me, and the wider community for allowing me to represent you as both councillor and deputy mayor over the past 17 months.”

Several female candidates for Mildura council called out abuse against them at the last election.

Mayor Liam Wood has thanked Ms Power for her “tireless efforts”.

“This is a difficult time for all councillors, and council as an organisation will continue to provide support when and as needed,” he said.

“I would again like to thank Cyndi for her dedication to our community during her time as a councillor, and the many positive impacts and connections she has made.

“Her wellbeing is our paramount concern during this time, and we ask the community to respect Cyndi’s privacy.”

A recount of ballots from the last election will be held to determine who will fill Ms Power's position, unless a by-election is required. The Victorian Electoral Commission will determine the next steps.
