Liberal MP Ian Goodenough emailed BuzzFeed News to say: "I was formerly a citizen of Singapore by birth. In 1984, I migrated to Australia with my parents at the age of 9. I applied to formally renounce my Singaporean citizenship in 2003 and this process was completed in 2004."

A spokesperson for Eric Abetz told BuzzFeed News that the Liberal senator is not a dual citizen of Australia and Germany, and a spokesperson for Liberal MP Paul Fletcher told BuzzFeed News he renounced his British citizenship in 2009.
