The Wallabies' opening four Tests of the season provided more questions than answers ahead of the upcoming Tri-Nations tournament against South Africa and New Zealand.
Deans and ARU high performance manager David Nucifora will sit down with O'Neill to assess the side's indifferent start to the campaign at ARU headquarters.
But while the timing of the early-season review has prompted fresh speculation over Deans' future, O'Neill rejected suggestions the national team is in crisis.
"It's a regular meeting, it's been in the diary since January," O'Neill said. "Robbie and I talk four or five times a week so there's nothing remotely resembling a crisis meeting. It's a mini review, we've had four Tests (and we need to discuss) what's good, what's not so good?
"It'd be fair to say that the inconsistency issue is something that worries us. We've got to be capable of putting teams to the sword and that's not quite there yet. Mind you, when I list the players who are injured, they are pretty valuable and extremely valuable parts of the team."
O'Neill, however, admits the current Wallabies lack the aggression of the great teams of the past. "It's all part of consistency," he said. "Whether it's mongrel or whether it's (about being) very uncompromising, it's all part of winning teams. If you look across the ages the really champion teams are uncompromising and sometimes they're not just satisfied with winning, they put you to the sword."
