In terms of terrorism, Ms Capp says programs run through Town Hall that help migrants settle into the community can help mitigate the risk of people being radicalised.
The Refugee Action Collective has called on political leaders - both federal and state - not to use the Bourke Street incident to drum up racism and fear.

In a statement to SBS News, the community's spokesman Ahmed Hassan said the community is praying for the victims, their families and those injured during the attack.
Mr Hassan says Somali Australians are peaceful people and is hopeful Australians can come together to ensure terrorism is eradicated.
Journalist and community activist Jamal Hummad says in this interview that while efforts to ensure the mosques and other places of worship are places for peace and harmony are important, there should not be any attempts to use events like this one to discriminate against one group of the community.
