The Hobart City Council is formally joining the push to change the date of Australia Day and will back aldermen who want to take part in the annual Invasion Day march.
At its full meeting on Monday night, a four-point motion was passed seven votes to two, with three aldermen absent.
The council is calling on other local governments to lobby the Federal Government to debate moving Australia Day from January 26.
Greens alderman Bill Harvey said the council also committed to the "non-politicisation and continuation of all citizenship ceremonies" on January 26.
"We wouldn't like to see the citizenship ceremonies, which we all believe are really important, taken away from us like it has occurred in a couple of other mainland councils," he said.
"We don't want to lose that, it is just too valuable but we also want to show our strong support for the Indigenous community of Tasmania and Australia that we support changing the date.
"There's no grounds to remove the council's ability to conduct the ceremony, I don't think there's any way that anyone from the Federal Government would attempt to remove that responsibility from the council."
As part of the motion, council will provide support for the annual Invasion Day march, organised by the Indigenous community, and back any aldermen who want to attend.
"Those of use who are in favour of this are responding to the community concern," he said.
"We represent a broad range of people in Hobart and there's growing interest from many people who believe we should change it and I think those who voted in favour of the recommendations support that."
The Lord Mayor had pulled no punches in July, calling her local government counterparts refusing to budge on a date change "pale, male and stale".
Sue Hickey was at another function on Monday night and did not take part in the vote.
She has put up her hand for Liberal Party pre-selection for next year's state poll.
A State Government spokesman said the Liberals did not support changing the date of Australia Day.
Several councils around Australia are also seeking to change the Australia Day celebration date.
In August, a Melbourne council angered Prime Minister Malcolm Turnbull after it dropped all references to Australia Day and ditched the annual citizenship ceremony.
