Humanitarian migrants applying for citizenship in 2014-15 sat 2.4 tests on average, compared to 1.1 for skilled migrants, highlighting that the last hurdle to becoming an Australian already poses a significant challenge to some applicants.
Prime Minister Malcolm Turnbull announced on Thursday an overhaul of the citizenship test designed to "make the country stronger".
"What we're doing is strengthening the multicultural society and strengthening the commitment to Australian values."
The test is to be revamped to include reading, writing and listening components, and will pose moral questions about family relationships.
Applicants will only be allowed to sit the test three times, and must prove they have a "competent" level of English.
