Prime Minister Scott Morrison was caught off guard during a live radio interview this week when asked why Caitlyn Jenner was allowed into Australia. The Keeping Up with the Kardashians star, 71, flew from LA to Sydney last week and is currently in hotel quarantine ahead of an appearance on Seven's Big Brother VIP. While it's understood Jenner obtained a special visa that means she isn't taking a hotel quarantine spot from an Australian, her arrival has nonetheless caused controversy as thousands of citizens remain stranded overseas and unable to return home. Mr Morrison, 53, was momentarily lost for words when Nova 919 hosts Ben Harvey and Liam Stapleton put him on the spot on the issue.
