Rory Best hopes to celebrate his 100th cap in style by becoming the first Ireland captain to beat the southern hemisphere's 'big three' in a calendar year.
Having led his country to historic wins over South Africa in Cape Town and New Zealand in Chicago, Best can complete the set with victory over Australia on Saturday, live on Sky Sports 2 HD from 5pm.
The Ulsterman will become Ireland's fifth centurion when he takes to the Aviva Stadium pitch, following in the footsteps of Brian O'Driscoll, Ronan O'Gara, Paul O'Connell and John Hayes.
And despite the loss of Johnny Sexton and Robbie Henshaw to injury following a bruising rematch with the All Blacks, Best remains confident they can mark his milestone with a victory over the Wallabies.
"It would be a massive deal for me, not only with the 100th cap but also captaining the side," said Best about the possibility of a hat-trick of wins over the Tri-Nations.
"We've talked about building a squad and we had to rely on that in South Africa with key players missing. It's going to be the same this weekend.
"The World Cup probably hit it home for us. We had been reasonably lucky for a couple of years with no injuries. Then it all came at once and we weren't really prepared, whereas now we feel a lot more comfortable.
"Obviously losing Johnny Sexton or Robbie Henshaw is massive for any team but when you've got guys like Paddy Jackson and Garry Ringrose stepping in and with the way they're playing at the minute, with that youth there comes a little less fear."
Best made his Ireland debut against New Zealand in November 2005 when he was introduced for the final four minutes at the old Lansdowne Road. Already on the pitch was his brother Simon and he says his elder sibling helped him settle into his new surroundings.
"You come into a camp for the first time and having grown up in the middle of the countryside, we were reasonably quiet, unassuming people," said the 34-year-old.
"We had been brought up surrounded by rugby and to come into this camp with your heroes, it is very intimidating. I was reasonably new to the Ulster team too so I didn't have that a lot of familiarity with those guys either.
"To just to have a familiar face there in Simon, he told me what physios to go to and he also looked after the tickets for all the games we played together."
Excluding Best, just two of the team that lost to 45-7 against the All Blacks in 2005 are still playing - Ulster team-mate Tommy Bowe and Sale scrum-half Peter Stringer, who turns 39 next month.
Best doesn't expect his career to extend as long as Stringer's but the hooker has no intention of hanging his boots up just yet.
"I've another year and a half on my contract and I'm really enjoying playing," he said. "I don't see myself finishing at the end of that but a lot of things can change over 18 months.
"While I still feel I can play at the top level, am enjoying it and am competitive, I'll play as long as I can. It's a sport I love and you're a very long time retired."
Prior to kick-off against the Wallabies, Best intends to take a moment and savour the occasion. It's something he encourages Ireland's new caps to do, to remember what they have achieved. Because before they know it, it will have gone by in a flash.
"To get to 100 caps is quite an effort," he said. "When I had that first cap, I think if you offered me another one that would have been enough for me, just to make sure I didn't end up on one cap.
"Obviously you'll try to stay focused because the game is all that matters. Me going out and winning my 100th cap, you'd swap that for a win any day. That's ultimately what's important.
"But it is important to take stock when you get out there, try to have a look around and take it in, because they will be the memories."
