Mirrabooka Square, City of Stirling and the Harmony Day Committee has teamed up to bring the community together with a range of free activities.
Mirrabooka Square centre manager Shane McLean said there were more than 50 nationalities represented in the 6061 postcode area.
“We are proud to support this and many other initiatives that help to unite our multicultural community,” he said.
There will be a free sausage sizzle, and children’s activities such as the chance to see native animals, face painting and a bouncy castle.
There will be stalls about local products and services, performances and from 6pm the popular Harmony Beatball will take place.
Mayor Giovanni Italiano said the message of the week was that everyone belonged.
The activities will be held on March 18 at the centre, at 38 Ashbury Crescent, Mirrabooka, 10am-2pm. Harmony Week runs March 15-21.
