Ahead of the Wallabies' biggest session of the week, in the lead-up to their first game against Georgia on Sunday morning (AEST), Kerevi was not involved in the warm-up.
The Fiji-born star was the only player from the 33-man Wallabies squad who was not on the field in the 15-minute window for reporters to take photos and video.
He was later seen in a dugout without his boots on as his teammates got the session underway.
Kerevi has been dealing with a hand injury since Australia's 23-20 Bledisloe Cup loss in Dunedin and did not face France in a warm-up match on August 27, when the Wallabies were thrashed 41-17 in Paris.
The team has given little away regarding Kerevi's availability for the Wallabies' tournament-opening clash with Georgia, but the 29-year-old's limited involvement points to him not being selected.
