Ireland will go head to head with the Wallabies in a three Test series next June.
The test series will be played at Suncorp Stadium in Brisbane on June 9, Melbourne's AAMI Park on June 16, and Sydney's Allianz Stadium in June 23.
It will be the first time Ireland have played a test match in Australia since 2010.
The Irish rugby team have played two test matches on tour against the Wallabies on your previous occasions but this will be the first time the Landsdowne Cup has been contested over three matches.
The new series was announced by Michael D Higgins as he continued his State Visit of Australia.
Speaking about the test series CEO of Australian Rugby Bill Pulver said there was "Wonderful rivalry between our two teams.We are neck and neck vying for that number three and number four position.
"We are sincerely looking forward to having a sea of green up and down the eastern seaboard in June next year".
The Wallabies have a winning record of 64 per cent over Ireland from 33 matches since 1927.
When Ireland lost their third successive World Cup match to Wales in August, culminating in an eighth-place finish in a home tournament from which many had reasonably expected a last-four place, the immediate response to failure was swift and summary.
At the launch of the Champions Cup season earlier this month, Munster captain Peter O'Mahony was guarded in his answers to a few questions but when it came to the replacement for Rassie Erasmus and the collective responsibility of the players, O'Mahony spoke more sternly than he had at any other point in the interview.
