Matthew Wade has questioned the implementation of DRS during Australia's second Test against India.
Australia endured a batting collapse on Monday as India put themselves within touching distance of victory at the MCG.
The hosts were reduced to 133-6 at stumps on day three, with a lead of just two runs, after losing four wickets for just 28 runs in the evening session.
However, there was some controversy over one of the dismissals, when Australia captain Tim Paine was judged to have been caught behind off Ravindra Jadeja.
Paul Reiffel's on-field decision of not out was overturned by third umpire Paul Wilson, who gave Paine the benefit of the doubt in a contentious run-out call in the first innings.
Paine was clearly frustrated, with the decision having been based on a Snicko spike and no evidence of an edge showing on Hot Spot.
Though that was the correct procedure, Wade has called for consistency, with Australia's review against Cheteshwar Pujara on day two – when there was no mark on Hot Spot and a minor spike on Snicko – not resulting in the India batsman being sent on his way.
"From what I've seen it looked pretty similar to the first ball of yesterday, the one we actually referred, I think it was off Pujara," Wade, who made 40, said in a news conference.
"So from all reports and what I've seen, Snicko showed a very similar thing, one was given out and one was not out.
"That's the way the cookie crumbles sometimes, but that's what it looked like from where we've been sitting and watching.
"I heard a noise on the Pujara one, I was at first slip at the time, and his bat was the only thing out there, and then we saw what you guys saw on the ground, which was a small spike. Either way if it was out or not out, consistency is all you want as a player."
Cameron Green (17 not out) and Pat Cummins (15 not out) saw Australia, who lead 1-0, through to stumps and Wade is hoping the pair can frustrate the tourists on day four.
"[India] bowled pretty well, pretty straight, made it hard for us to go out and score," he said. "But we've only got ourselves to blame.
"We'll take anything [in terms of a lead]. It'll be really nice for these two to get a nice partnership together – something we haven't done enough over this Test match. Anything over 100 would be good."
