Headline act the Highlanders need to repeat the same lines, passion and commitment from last week, hoping that will bring about the same result tonight.
Much has been said about the drama of last week's South Island derby but for the Highlanders that is now forgotten as the Sydney-based side hoves into view.
Highlanders coach Jamie Joseph has made just the two changes to his side from last week.
Ben Smith is not right after a head knock last week and Colin Slade will start at fullback.
After being absent for five weeks, Kade Poki gets back on his favourite right wing, with Buxton Popoali'i dropping to the reserves.
Poki strained a medial ligament in his knee against the Crusaders in a warm-up game early last month but is finally fit and luckily it was not the knee which has hampered him previously.
He will be eager for work tonight, but the Highlanders will need to be on their game against a side which defines grittiness.
Big strong forwards, a resourceful inside-back combination and talent out wide - the Waratahs are rock-solid in most departments if lacking a bit of the X-factor.
Joseph said the team had recovered from last week's bruising encounter and had prepared well for the Waratahs.
"The guys were sore from last week but they are sore every week. They way the guys like to play is that they do not have anything left in the tank," he said.
"You would expect that. But the guys have not let themselves down this week."
Joseph said he was not thinking about managing his team over the season; he was simply focusing on week to week.
Hence the minimal changes tonight, as nothing breeds confidence like winning.
Smith's absence at the back will be felt as his ability to run the ball back is a key for the Highlanders.
Slade is an able substitute and will want to stamp his mark on the game.
The Waratahs do lack the power of a match-winner with Kurtley Beale now showing his wares in Melbourne, but in lively halfback Sarel Pretorious have a player who has the ability to turn a match.
Joseph knows his side is in for a big game.
"They are a quality side on paper. Big, strong ball-runners in the pack, with good locks, a lively halfback and good finishers out wide. So we know they will be full of fire.
"Last week, the crowd really helped us, the way they got in behind us and really helped us dig deep in the final few minutes. I know the guys got a real lift from the support they get."
The Waratahs have a new coach in Michael Foley who is trying to instil more discipline and enterprise into the side but it may take time.
For the Highlanders, the time is now. They need to keep up the momentum gained at the start of the season, and show they are the real deal.
Beating a top Australian side will only swell their admirers.
