Australia have revamped their decision review system strategy in a bid to simplify the process and limit the amount of voices involved in making a call.
Australia's inability to get their referrals right became a key part the Ashes, where they regularly failed to overturn decisions or didn't challenge incorrect ones.
Never was that more blatant than in the nail-biting third Test loss at Headingley, where a review was wasted on a Pat Cummins lbw shout.
Moments later, Nathan Lyon couldn't review a plum lbw decision that would have gifted the game to Australia before Ben Stokes finished England's one-wicket victory.
Under the new plan, only the bowler and wicketkeeper Tim Paine will have a proper say on reviewing caught behinds, while in lbw appeals the point fielder will also be used.
"We're just keeping it very simple. We're trying to get the bowler and keeper's (thoughts), obviously," quick Josh Hazlewood said.
"And height is a big issue in Brisbane with the lbws, so we're trying to get someone from point to have a quick chat.
"Keep it simple. Why didn't the umpire give it out? At least we have a process then and can judge ourselves if we are getting better or worse.
"If someone hears something out of the blue, they can always come in and yell it out if it's very clear. But just trying to restrict it to those three people."
Australia's new process passed its first test on Thursday, with the hosts reluctant to overuse the system as they rolled through Pakistan for 240 at the Gabba.
Only once was it called upon, with Mitchell Starc getting Shaheen Shah Afridi caught behind on referral late on the opening day of the series.
It comes after Australia used the review system 35 times in the Ashes either while batting or fielding, for just eight decisions in their favour.
