Jonny Bairstow insists he is ready to replace Matt Prior in the England side for the first Ashes Test at the Gabba if required.
Bairstow is on standby to wear the gloves in Brisbane as Prior is currently receiving treatment for a calf injury.
And the Yorkshire wicketkeeper got his first taste of action on the tour in the final warm-up game at the SCG against the Cricket Australia Invitational XI.
Having taken three catches in the first innings, Bairstow then enjoyed a stand of 106 with Joe Root on day three in Sydney.
And Bairstow, who has been working with England wicketkeeping coach Bruce French on the tour, has no qualms about stepping up to face Australia.
"It is exciting. I am pleased with the way I have kept wicket over the last couple of days and it is good to get the miles in the legs," he told Sky Sports.
"There's nothing like keeping for a full day, you can do as much fitness as you like but keeping in this heat and getting used to the conditions out here is important.
"The preparation that I have been working with Bruce on and the technical side of things, it is every day process, so if that opportunity does come along I don't see any reason why I can't take it. But at the end of the day we are all hoping that Matt is going to be fit.
"The medical team are keeping things close to their chests but Matt seems fine and is as chirpy as ever."
Bairstow gave a timely reminder of his abilities with the bat with a well-worked 48.
"Personally it was really good to spend some time out at the middle," he added.
"It wasn't easy coming off for the rain and intervals but overall it was pleasing to get out there and hit the ball in the middle of the bat.
"The main thing is spending the time out there. It is good to be out there in a match situation, putting scores on the board that have hopefully put us in a strong position."
