Andy Farrell and Joe Schmidt just can't avoid each other.
For the second November in a row, Ireland are hosting the Wallabies in Dublin, and between all of that, Farrell led the British and Irish Lions to a Test series win against Australia.
Schmidt is due to step down as head coach later in 2026, handing over the team to his old assistant Les Kiss, so it's possible this Saturday could be the lasts time we see the former Leinster and Ireland boss coaching a Test in Dublin.
Both side come into the game searching for inspiration.
Ireland were 41-10 winners against Japan last time out, but Farrell wasn't impressed with his side's display, while earlier this month they were swept aside in the final quarter by New Zealand.
Australia appeared to have turned a corner when they defeated the Lions in that third Test in Sydney in August, and followed it up with a stunning win against South Africa in Johannesburg, but last week's defeat to Italy has undone a lot of that good work, and put real pressure on the Wallabies, who have now lost five of their last six games

WEATHER
Thankfully, the orange weather warning in Dublin is set to clear by Saturday afternoon, with a largely dry evening forecast, with temperatures around 10C expected.
There was a time when Ireland couldn't buy a win against Australia, but in the last 20 years this has become a fixture that Irish supporters expect to win, rather than hope to.
It's 12 years since Australia last won in Dublin, a 32-15 hammering which, coincidentally, came very early on in the Joe Schmidt era.
The Wallabies have only beaten Ireland once since then, an 18-9 win to take the opening game of their Test series in Brisbane in 2018, a series Ireland would come from behind to win, while they would also come out on top in the 2022 and 2024 meetings in Dublin.
While this has become a one-sided rivalry in terms of wins and losses in recent times, a look under the bonnet off those games would suggest otherwise.
Ireland have won six of their last seven meetings with the Wallabies, but all six of those Irish wins have been one-score games, with the two largest of those wins being by five and four points respectively in the 2018 series down under.
Incredibly, each of the last four meetings in Dublin have been won by Ireland by exactly three points.
Two of those have come in the Andy Farrell era; In November 2022, a late Johnny Sexton injury put Jack Crowley in for his first Irish start, before a late Ross Byrne penalty gave Ireland a dramatic win, while 12 months ago Australia came within seven minutes of a surprise win, but a late Gus McCarthy try eked out a 22-19 victory.
On each of those occasions, Australia arrived in Dublin in poor shape but dragged Ireland into a street fight, and once again they are struggling for form this week.
Since their incredible win against the Springboks, the Wallabies have won just two of their last eight games, beating Argentina and Japan by four points each.
That win 19-15 win against Japan was greeted more like a defeat than a win, while they have lost back to back games on their northern hemisphere tour to England and Italy.
Ireland make a total of nine change to their side after last week's win against Japan, with some interesting calls mad by Farrell.
Mack Hansen comes in at full-back, replacing the injured Jamie Osborne, while there are also returns in the backline for James Lowe, Stuart McCloskey, Sam Prendergast and Jamison Gibson-Park.
Up front, Paddy McCarthy is given his first start at loosehead, with Dan Sheehan and Tadhg Furlong also coming into the front row, while Jack Conan replaces Nick Timoney in the back row.
Joe Schmidt has handed James O'Connor a start at out-half, among six changes from the side that were defeated by Italy in Udine last week.
O'Connor, who wasn't involved in last week's defeat, comes straight into the 10 shirt, with Carter Gordon ruled out.
Schmidt has also axed tighthead prop Taniela Tupou from his matchday 23, with the Racing 92 prop replaced by Allan Ala'alatoa in the starting team, with Zane Nonggorr on the bench.
Rob Valetini returns to the starting back row, with Tom Hooper moving to the second row and Nick Frost dropping to the bench.
Len Ikitau comes into the centre, partnering Joseph-Aukuso Suaalii in the centre, while Max Jorgensen is at full-back, and Filipo Daugunu on the right wing.

WHAT THEY SAID:
Andy Farrell (Ireland head coach): "This is the window for us. We talk about all those players who haven't quite got the experience but we need to give them that and this is the window to do that.
"And also, on the back of it, I think there's a pretty determined senior members of the squad that's gonna turn up as well on Saturday night."
Joe Schmidt (Australia head coach): "How do you learn and how do you get better? I think the only way to do it is in the arena. And at some stage, you've got to trust everyone in your squad. If you've selected them, then they have to be ready for whatever is demanded of them once they put on a Test jersey.
"So it's a balance that I don't think anyone gets right all the time. Even some of those countries with really, really good depth who can replace player for player without any observable kind of dilution of what they can deliver."
