Latu has played four matches previously for the Wallabies.
“Right now he’s our most-capped hooker in Australia, so he’s got that little bit of experience playing in the big match atmosphere,” said Wallabies coach Michael Cheika.
“Anaru Rangi has had a really good season with Melbourne too so he’s definitely not out of the equation. I’m just keen for the two uncapped hookers (Paenga-Amosa and Fainga’a) to have a little experience around.”
Australia will play Ireland in a three-Test series which begins this week.
The first match will be played on Saturday night kicking off at 8pm AEST in Suncorp Stadium

The second and third matches of the series will be played at AAMI Park in Melbourne and Allianz Stadium in Sydney respectively.
World No.2 Ireland are the favourites to win despite the Wallabies boasting a home ground advantage, priced at odds of $1.73 to claim victory at Suncorp.
