Ireland will tour Australia next year in the first ever three-Test series played between the teams.
The matches will kick off in Brisbane on 9 June, followed by Melbourne a week later and then Sydney on June 23.
Ireland won their two most-recent encounters with the Wallabies, in Dublin in 2014 and 2016, but have not played a Test in Australia since 2010.
It will be a formidable task for the Irish, with Australia not losing at home to them since 1979.
