Launceston mayor Albert van Zetten and Alderman Hugh McKenzie have joined developer Errol Stewart, accountant Janine Healey and Jo Archer to form the Peace Trust.

The group will volunteer their time to help enable July's Community Festival for Peace and the construction of a Peace Garden in Launceston's Kings Park.

"We're going back to the notion that people at a grassroots level get involved in living and behaving in a more peaceful way and expressing goodwill," Ms Archer said.

"Here, as we are slowly becoming more culturally diverse, we need to help our community enjoy that diversity and understand it and build awareness of how to be in a diverse community."

She said peace was not only the absence of war; instead, it was about the behaviour of people as citizens of small communities and global societies.

The Community Festival for Peace was the brainchild of former senator Jean Hearn, who was inspired by the late governor Peter Underwood's Anzac Day speech in 2014.

The event will serve as a platform for people to define what peace means to them and run from July 10 to 12.

Activities planned for the event include a writing competition, a community choir and an art exhibition.

Ms Archer encouraged community members to donate what they could to help achieve the trust's mission.
