Religious schools should be required to admit a certain percentage of teachers and students from other religions so children can learn about other faiths, the peak body representing Hindus has told the Morrison government.

The Hindu Council of Australia says it is afraid the government's proposed freedom of religion laws could have "unintended consequences", such as religious segregation and limiting employment opportunities for some religious groups.

Hindu Council vice president Surinder Jain said although religious schools should have the freedom to teach their particular faith, the bill should ensure they also employ staff and admit students from diverse backgrounds.

"Children in religious schools are growing up never having come across someone of a different religion. That's not good for a harmonious, multicultural society," he said.
