The Indian team scored 10 points as come-back man Adrian Sutil finished seventh and Paul di Resta eighth at Melbourne.
"We have scored points in Sepang the last three times we raced there, including a double-points finish last year, and I believe we can build on the early-season momentum to bring home a valuable result," Team Principal Vijay Mallya said.
Mallya said now they will be watched curiously by all after a superb result in the season-opening race.
"The 2013 Championship is just at the beginning, and it is important not to get carried away with enthusiasm."

Di Resta said, "We've got some things we need to pick up on and we can definitely make some improvements, but we're in a good place to start the season. Also, we've seen already that we can make a stop less than some of our competitors so let's see if that remains the case in Malaysia."
"In the rain it's easier sometimes to be at the front and race with the top teams, but in the dry it's more difficult and normally never happens," he said.
However, he said he always looks to go a step further.
"It's amazing to see that it was possible in Australia and don't forget that Nico (Hulkenberg) led for this team at the final race of last year too. There are opportunities, and if you believe in it, you can take those chances. If you don't believe you can win, you will never win. It's just an approach, I think," he said.
