England are considering a formal complaint regarding the accuracy of the 'Snickometer' technology after controversy engulfed the opening day of the third Ashes Test. Australia's Alex Carey admitted he got " a bit of luck" before making a crucial century in Adelaide.

He survived a sensational review when on 72 and later claimed that he edged a ball that was given not out by DRS (Decision Review System) technology. Carey appeared to make contact shortly after Josh Tongue had dismissed Josh Inglis, but umpire Ahsan Raza turned down the mass England appeals.

Real-Time Snicko (RTS) is Australia's DRS, and showed a huge spike, which suggests that Carey had edged the ball. But the timing did not align with pictures shown and TV umpire Chris Gaffaney opted against overturning the decision.

Carey, who later confessed to making contact, went on to make 106 as Australia reached 326 for eight, a commanding position to go into day two.

"I thought there was a bit of a feather or some sort of noise when it passed the bat," said Carey. "It looked a bit funny on the replay, didn't it, with the noise coming early? If I was given out, I think I would have reviewed it - probably not confidently though. It was a nice sound as it passed the bat, yeah.

"Snicko obviously didn't line up, did it? That's just the way cricket goes sometimes, isn't it? You have a bit of luck, and maybe it went my way today."

England's bowling consultant, David Saker, argued that RTS had been calibrated incorrectly throughout the series. The host broadcaster decides which brand of technology to use, with Sky Sports preferring UltraEdge rather than RTS.

"The boys were pretty confident he hit it," Saker said. "I think the calibration of the snicko is out quite a bit and that has probably been the case for the series. There's been some things that don't really measure up. At that stage, it was a pretty important decision. Those things hurt, but you get through it. In this day and age you'd think the technology is good enough to pick things up like that."

When asked if England would be making a formal protest, Saker replied: "I don't think we've done anything about it so far but after today, maybe that might go a bit further. There have been concerns about it for the whole series. We shouldn't be talking about this after a day's play, it should just be better than that. It is what it is."
