The Wallabies will be back in Cardiff in 2017, the fourth plank in their Spring Tour confirmed on Wednesday.
Wales announced its end-of-year Tests on Wednesday morning (AEST), with Tests against the Wallabies,Georgia, New Zealand and South Africa to come.
Australia's Test will come in the second week of its current four-week Spring Tour, in between its historic Japan Test and a Twickenham showdown with England.
The announcement all but completes their international Test calendar, though there was believed to be the option to explore a Barbarians Test at the end of the year as well, while South Africa is yet to confirm its home Rugby Championship venues.
Australia has travelled to Cardiff on all but two Spring Tours since 2005, with the only exceptions being the 2007 and 2015 World Cup seasons, though they faced off against the Welsh in the pool stages of both of those tournaments.
Last season's 32-8 victory over Wales was the Wallabies' 12th straight win against the Welsh, with their most recent defeat coming in 2008.
The Wallabies season kicks off on June 10 against Fiji.
