Jacks will play his first Test for three years in the only change as England dispensed with the all-pace attack used in the first Test defeat in Perth.
The 27-year-old got the nod ahead of Shoaib Bashir for the pink-ball match to add more depth to the England batting.
All-rounder Jacks has played in two previous Tests and claimed a five-wicket haul on debut against Pakistan in 2022.
He has mainly been used by England in white-ball cricket.
"Everyone knows what a brilliant cricketer he is," England batsman and Jacks' Surrey teammate Ollie Pope told reporters.
"The way he's grown over the last few years, we've seen his white-ball game really go forward. It's a great opportunity for his red-ball, too.
"He's obviously got that style of spin bowling where he can get some bounce and turn off the pitch, then everyone has seen the skills he's got in the white-ball format.
"He can take on a really good attack."
Travis Head's whirlwind century carried Australia to an eight-wicket victory inside two days in Perth as they went 1-0 up in the series.
Pope, batting at three, scored 46 and 33 and said he was "pretty annoyed" with both of his dismissals.
"At the same time, I was happy with how I was playing up until the moment I got out," he added.
"If I can start my innings like that as much as I can while I'm out here, hopefully some big runs will flow."
He added of England's poor batting in Perth, where they were out for 172 and 164: "There's a few lessons there, I guess, individuals would take from last week and then put them into practice this week."
England team: Ben Duckett, Zak Crawley, Ollie Pope, Joe Root, Harry Brook, Ben Stokes (captain), Jamie Smith, Will Jacks, Gus Atkinson, Brydon Carse, Jofra Archer.
