Alex Carey will replace Tim Paine as Australian wicketkeeper for the first two Tests of the men's Ashes series, after the South Australian was added to Australia's 15-man squad.
The Redbacks' Carey was in competition with Western Australian Josh Inglis to replace the former Australian skipper, but Cricket Australia on Thursday announced Carey's inclusion in the squad, a week out from the first Test at the Gabba.
Carey capped his bid for a spot in the team with a century for South Australia against Queensland in the domestic one-day cup competition last weekend.
"I think my game is in pretty good order … for me, it's to do my job behind the stumps, provide what I can with the bat and do it the way that I do it," Carey told reporters on Thursday.
"I'm going to go and play with a big smile on my face."
Carey, 30, made his one-day international debut for Australia against England in Brisbane in January 2018, and began his T20 international career against New Zealand in Sydney a month later.
He averages 34.73 in Sheffield Shield cricket for the Redbacks, with five centuries and 13 50s.
Carey said he felt "confident" in his ability to keep to Australia's much-vaunted bowling attack, having played with them in the shorter formats of the game.
"I've been fortunate enough to keep to them in one-day cricket and some T20 cricket as well," he said.
"I'll be preparing how I usually would for a four-day match. I'll get behind the stumps to Gaz [Nathan Lyon] and the quicks.
"Hopefully we get outdoors soon, there's obviously been quite a bit of rain around [in Brisbane].
"It is Test cricket and it is a dream come true, but my job is to focus on what I've done in the past to get to this moment and not be too overwhelmed."
Carey said he felt for Paine and his family, expressing his and the team's support for the former Australian Test captain.
"Hopefully we see him back as soon as possible," he said.
National selection panel chair George Bailey said Carey deserved the opportunity to make his Test debut.
"Alex has been a regular member of the national side in white-ball cricket, particularly in the one-day game," he said in a statement.
"He is an excellent cricketer and a fine individual who will bring many great strengths into the team."
