The Wallabies are set to start Jordan Petaia at fullback in the second Test against England.
With Tom Banks out long-term after a broken arm, it was expected Rookie of the Year Andrew Kellaway, who went to the back in the first Test victory, would retain the position for Saturday's clash at Suncorp Stadium.

However, Kellaway has picked up a minor hamstring injury, which will put the Petaia fullback experiment on full display.
It's a move that has floated since last year, with Wallabies coach Dave Rennie admitting he was keen to see how he'd make the move.
Rennie selected Petaia to play fullback for the Barbarians Test against Samoa, however, a bevy of COVID cases forced the game's cancellation.
Bryce Hegarty's departure from the Reds opened the door for him to gain some valuable experience at Super Rugby level, flagged at the end of last season by Reds coach Brad Thorn and GM of Rugby Sam Cordingley.
"Thorny's always had his eye on this for quite a while," the former Wallabies halfback said back in November.
"He played a lot of his school rugby at 15, Thorny's seen that as a potential opportunity for 2022.
"Without giving too much away, I'm sure Thorny sees that as a future position for Jordy."
After starting on the wing, he was thrust to fullback in round four of Super Rugby Pacific against Fijian Drua, scoring during their 33-28 victory.
Further mixed performances followed before he was struck down with injury against the Rebels in April.
His return coincided with strong performances from Jock Campbell, with Thorn opting to keep Campbell in the 15 jersey and moving Petaia to the wing.
This has produced some of Petaia's best performances before a raft of injuries saw him moved back into the centres.
The injury to Banks brought the 22-year-old back onto the wing as he delivered a starring performance to get the Wallabies home.
The question now remains the same as it did at the start: just how good of a fullback is Jordan Petaia?
