Australia were forced to make a late change to their replacements bench for Saturday's (local time) test against Italy in Florence with James Hanson taking over from Tatafu Polota Nau as backup hooker.
Polota Nau dropped out of the side after failing to recover from soreness suffered in last weekend's 20-14 victory over old rivals England at Twickenham.
Queensland Reds hooker Hanson, 24, made his debut for the Wallabies in the 18-18 draw with New Zealand last month and will provide cover for the experienced Stephen Moore who starts the match against Italy.
Elsewhere, Wallabies lock Rob Simmons will have his appeal against an eight-week ban for a tip tackle against France heard on Tuesday.
