Kerevi will partner Tevita Kuridrani in a midfield with a combined weight in excess of 200 kgs, while the 208-cm tall Arnold will provide the grunt to complement Rob Simmons' organisational ability in the second row.
In the selection of outside back Dane Haylett-Petty, the third debutant, Cheika resisted the temptation to unleash another big rookie back on the English and Fiji-born Taqele Naiyaravoro misses out on the matchday squad altogether.
Haylett-Petty, who plays at fullback for the Western Force, starts on the wing with Israel Folau retaining the number 15 jersey despite talk that he might move into the centres.
The midfield partnership was Cheika's biggest selection conundrum given the absence of Kurtley Beale and Matt Toomua through injury and incumbent inside centre Matt Giteau because of his French club commitments.
In opting for the Kerevi-Kuridrani partnership, he has given up the second receiver that Australia have locked in at inside centre for the last few years in favour of defensive solidity and potential line-breaks in attack.
Christian Lealiifano would have offered the second playmaker option but has been absent from the Wallabies training camp to be with his wife for the birth of their child and he starts on the bench as back-up to flyhalf Bernard Foley.
Scrumhalf Nick Frisby is a fourth potential debutant, having earned a place among the replacements for the match at his home ground with some fine form for the Queensland Reds this season.
Arnold aside, Cheika has stuck largely with the pack that earned plaudits at last year's World Cup with David Pocock at number eight alongside Michael Hooper at openside flanker.
Tighthead prop Sekope Kepu arrived late to the training camp and is relegated to the bench with Greg Holmes getting the start in the front row alongside skipper Stephen Moore and loosehead Scott Sio.
England coach Eddie Jones names his team later on Thursday.
