It is the second time Mr Kircher and Mr Mutch have gone up against each other for the mayoralty. Mr Kircher also beat Mr Mutch by 4774 votes in the 2019 local body elections.
Mr Kircher said he was thrilled to be voted in again and thanked the district for its support.
"I think it’s as humbling now as it was the first term and particularly given the campaign that’s been run," Mr Kircher said.
"I’m just grateful people think we’re heading the right direction over all.
"We can always do better but I think the general direction is quite positive and yeah, just pleased to be able to work with the new team over the next three years."
