Smith was named captain today owing to regular skipper Michael Clarke's injury breakdown during the first Test which the hosts won by 48 runs.
"I am only a temporary solution at the moment since Michael is out injured unfortunately," the 25-year-old Smith told reporters after his appointment today.
"It's been a pretty whirlwind 18 months for me personally and for the team and for this to come up so quickly, it's an amazing thrill, something that I guess I have always dreamt of doing," he said.
The all-rounder, who smashed 162 not out in the first innings and was 52 not out in the second essay of the opening Test, became the 45th Test captain of the side. The second Test of the four-match series starts here on Wednesday.
"I have told the boys that I have no intentions of changing any plans. I think we have come a long way and we are playing some good cricket so we are going to continue with that aggressive and positive brand of cricket," Smith said.
The baby-faced youngster said he has got the full backing of Clarke, whose cricketing future has been thrown into jeopardy due to nagging hamstring and back injuries.
"I spoke with Michael this morning. He sent me a text and told me 'give me a buzz when you are free'. I gave him a call and he is very proud of me. He is just really excited for me to lead Australia this week," he said.
