HORSHAM Rural City mayor Mark Radford hopes to retain his position for the final year of the council's four-year term.
Cr Radford declared he would stand for re-election when councillors vote at a statutory meeting on November 4.
Pam Clarke and David Grimble told the Mail-Times they remained undecided on their intentions for the mayoral vote, while Alethea Gulvin and John Robinson have ruled out a contest.
Josh Koenig and Les Power did not respond to requests for comment.
Cr Radford said he reached his decision after talking with family.
"I have appreciated the opportunity to lead our council for the last 11 months and if re-elected, I will commit to continuing to give the responsibility my best shot," he said.
Cr Clarke said she would decide at the statutory meeting whether to stand for mayor.
She said the role involved a lot of sacrifices.
Cr Clarke said it was important mayoral candidates had the support of their family in making the decision. She has served two terms as mayor - between 2016 and 2018 - and said doing this had been a "privilege".
"For any councillor generally, lifestyle is the biggest concern," she said.
"You have to commit so much time to it. Unless you have a good reason, you can't say no to anything. You have to make yourself available - whether it be for a Rotary club's annual general meeting or something else."
Cr Grimble said he hadn't finalised his decision, but said his work as a farmer, his family and community expectation would all influence his decision.
"Physical health is also in the back of my mind - I had a heart attack in April," he said.
Cr Gulvin said she didn't think she would have the time to fulfill both her duties as a teacher at Holy Trinity Lutheran College and mayor to the best of her abilities.
"When my dad (Iain) was on council, he said someone in their first term shouldn't be mayor, and that's stuck with me," she said. "I don't think I'd have the ability to do it, hours-wise. If I'm not doing my job well at the school, I'm not happy."
Cr Robinson said he saw "no point" in standing for mayor, as he felt there would be no prospect of him gaining enough support to win the vote.
A council spokesman said the statutory meeting would be open to the public. He said the vote to elect the mayor would be conducted via a secret ballot.
The statutory meeting is at Horsham Civic Centre on November 4, starting at 5.30pm.
