Bird, the leading wicket-taker in the domestic Sheffield Shield, will take the new ball in front of a bumper crowd at the Melbourne Cricket Ground on Boxing Day as Australia seek to seal the three-match series 2-0.
"I got the call from Mickey yesterday to say that I'm in the final 11," Bird told reporters at the MCG on Monday, referring to Australia coach Mickey Arthur.
"So yeah, it's very exciting and I'm looking forward to it.
"In the last 18 months I've been pretty successful in first-class cricket.
"I suppose I've got a pretty good record here at the MCG as well, and I guess there's always an element of luck in there as well. There's a few injuries going around.
"In saying that I feel like I'm ready for test cricket and hopefully I can repay the faith in Mickey and the selectors."
Australia will rest 22-year-old paceman Mitchell Starc as part of the team's controversial rotation policy, following a raft of injuries that have gutted their pace bowling stocks.
Starc, who took a five-wicket haul to help Australia secure a final-hour victory in the first test in Hobart, was disappointed with the decision, Arthur said.
"That's a real tough decision to make. It's a tough conversation with Mitch. He took it very, very well," Arthur said.
"(He's) clearly very disappointed and we wouldn't expect anything other than that."
Starc's omission sees Mitchell Johnson recalled to the side after he was dropped following the third and final test against South Africa, which Australia lost by 309 runs to concede the series 1-0.
Johnson replaces Ben Hilfenhaus, who broke down during the Hobart test and joined James Pattinson and Pat Cummins on the sidelines with a raft of other injured fast bowlers.
Only Peter Siddle, who took nine wickets in a man-of-the-match performance at Hobart, has been retained in the pace attack, with Australia forced to re-shuffle their fast bowlers for a third consecutive test.
Nathan Lyon has been retained despite weathering a chorus of criticism from former players and pundits after failing to take second innings wickets in the previous tests against Sri Lanka and South Africa.
"Nathan is a very good bowler and will be a very good bowler for Australia going forward," Arthur said, giving the spinner his full backing.
Australia captain Michael Clarke continued to be rated a "50-50" chance of playing after suffering a hamstring strain during the Hobart test but would be given until the last minute to prove his fitness, Arthur added.
"If I was a betting man I would bet on Michael Clarke being in the team on Boxing Day," he said.
Batsman Usman Khawaja remains on stand-by to replace Clarke.
The teams will play the final test in Sydney from Jan. 3.
