"The Australian Rugby community is mourning the sudden death of former Wallaby captain and Hall of Famer John Hipwell," the ARU said on Twitter.
Former Wallabies teammate and ARU official Geoff Shaw paid tribute to the former half-back, who captained Australia in nine Tests.
"John Hipwell was a Wallaby captain, a great bloke and a very close friend of ours," Shaw said in a statement.
"He played for a very long time and made a lot of friends. He will be missed."
