The Wallabies were kept scoreless in the second half and survived a series of late scares to land an unconvincing 22-19 victory over Italy at Stadio Artemio Franchi in Florence.
Italian five-eighth Luciano Orquera missed a penalty attempt from 40 metres out with just one minute remaining to tie up the game to ensure Australia held on to win their second consecutive match of the European tour on Saturday (Sunday NZT).
Australia's set piece problems resurfaced, particularly in the scrum, with the Italians enjoying possession and territory dominance after winger Nick Cummins' try in the 19th minute helped the Wallabies to a 22-6 lead at halftime.
The Italians came out swinging in the second half with a try in the opening minute after the break to No.7 Alessandro Barbieri, who crossed after Wallabies lock Sitaleki Timani spilled in Australia's half.
Replacement prop Michele Rizzo kicked the loose ball and Barbieri, who spent 10 minutes in the sin-bin in the first half for slapping the ball down at a ruck, dived on the ball and Orquera converted to make it 22-13.
