The Roosters superstar has been handed the No.13 jersey for Saturday's (Sunday morning AEDT) clash at Twickenham by coach Joe Schmidt, who's wasted no time thrusting the new boy into the midfield cauldron.
Suaalii's bow at outside centre launches his $5.35 million, three-year deal with Rugby Australia in the most high-profile fashion, getting a place in the starting XV when many had expected him to be given his introduction off the bench.

It comes just six weeks after the 21-year-old Suaalii played his last NRL game for the Roosters in a preliminary-final loss to the Storm and will be his first game of union since representing the Australian Schoolboys team five years ago.
Suaalii will be joined in the centres by experienced 35-cap Len Ikitau in what looks like the combination Schmidt sees as being the way forward for the Wallabies with a view towards next year's Lions tour.
It's a big call for a match the Wallabies urgently need to win after three straight Rugby Championship losses and five defeats in their last six.
They're undertaking a 'grand slam' tour of the British Isles and will be desperate to avoid defeat at the first hurdle at a venue where they haven't won since the 2015 World Cup clash.

Suaalii is the only change to the starting XV from the Wallabies' last Test, the 33-13 defeat by New Zealand in Wellington.
There are 14 players in the matchday 23, captained by Harry Wilson, who will play at Twickenham for the first time.
There's no place in the 23 for the returning stars, Samu Kerevi and Will Skelton, evidently not yet deemed in the right condition for the fray following England's narrow loss to the All Blacks last weekend.
Schmidt said: "The side has adjusted well to the travel and have had a couple of trainings up here to prepare for what will be a very tough challenge on Saturday.""Playing in front of vocal home crowds in some of the most renowned Rugby stadiums in the world is an exciting prospect, with many of the players on their first Spring Tour."
