Marcus North believes Australia now have a psychological edge over England after dominating the fourth Test at Headingley.
England struggled in the first Test at Cardiff last month but were given a major boost as the tail hung on to secure a draw.
The side then looked to have drawn confidence from that escape as they outplayed the Australians in the victory at Lord's.
But while they were in the driving seat for much of the third Test at Edgbaston, they were unable to get the wickets they needed on the final day as the visitors held on for the draw.
And, with Australia on the verge of victory after just two days at Headingley, North believes that his team-mates are now in pole position for the series.
"Earlier in the series, England got that draw at Cardiff and then really came out at Lord's firing and took that momentum forward," he told Sky Sports.
"England went into the final day at Edgbaston thinking they were going to win and, for us to blunt that, it's really given us the momentum now."
He added: "I think we learned a lot from the way we went about it at Edgbaston. It's a mental thing.
"We had to be a bit more disciplined with our batting and I think we showed that in how we applied ourselves here at Headingley and we got our rewards."
England closed day two on 82 for five in their second innings, still trailing by 261 runs.
