Here are the teams for the Tahs and Lions.
As you can see, the Lions look exceptionally strong, with a couple of familiar names in the starting team: Mack Hansen, Finlay Bealham and Sione Tuipulotu were all raised in Australia before finding their way to Ireland and Scotland to play Test rugby.
There has been a late change for the Lions: young backrower Henry Pollock has been withdrawn with a tight calf, meaning skipper Tadgh Beirne moves from lock to no.6, and Scott Cummings comes into the second row.
Blair Kinghorn and Hugo Keenan are both playing their first matches on tour, as well, and are both sharp with the ball in hand.
As with other Aussie sides, the Waratahs are down on Wallaby troops but there are a couple of key men in key spots. Taniela Tupou is starting at tighthead and you’d have to think his Test chances ride heavily on a strong showing here.
Andrew Kellaway has also come back from the Wallabies and will be a key man to bring calm and composure. So too will backrower Rob Leota, and new Tahs recruit Matt Philip, who’ll bring presence from the bench.
Interestingly, Wallabies squad member Tane Edmed is not starting at no.10, however. Jack Bowen will start and Edmed - who is heading to the Brumbies next year - will come from the pine.
