Scott Morrison called an Australian sporting legend just moments after the clock hit 12 on New Year's Day to tell her he had changed the words to the national anthem.
The prime minister immediately picked up the phone and called Olympic gold medalist and sporting hero Cathy Freeman to deliver the news in person.
The sprinting legend of the 2000 Olympics tweeted her astonishment at 2.38am on January 1 - before the New Year was even three hours old.
'What a way to start the year!!! A phone call from our Prime Minister to say we are 'one and free'! Thank you,' she tweeted.
