The next challenge facing Ireland's Grand Slam heroes will be in Australia as they take on the Wallabies in a mouth-watering three-test series.
Joe Schmidt's team have soared to number two in the world rankings, after clocking up 12 consecutive victories. They have not tasted defeat in more than a year.
But Ireland's record in Australia is poor and they will have to reverse a losing trend to continue their unbeaten run.
The Wallabies have hosted Ireland ten times since 1987, winning all ten tests.
To find the last Irish victory on Australian soil, you need to go back to 1979 when Olly Campbell kicked Ireland to victory in a tryless encounter at the Sydney Cricket Ground.
That win, and a 27-12 victory a week earlier in Brisbane, gave the tourists a clean sweep.
Ireland famously fell one-point short against the Wallabies in the 2003 Rugby World Cup in Melbourne but that's as close as the Irish have come to a win on Australian soil over the past 30 years.
The Irish have, however, won three out of four of the most recent clashes including a famous win over the Wallabies at the Rugby World Cup in New Zealand in 2011.
Australia has struggled against northern hemisphere opposition in recent years, losing all three tests against England in 2016 and going down to Scotland last year.
Irish rugby fans in Australian will now be hoping that the Irish arrive with all their Grand Slam stars.
