The 19-year-old made 109 off 144 balls against India A to help his side reach 337 for five at stumps.
Konstas was glad to be back in the runs after a lean tour of the West Indies earlier this year.
"I felt I had to face quite a few demons mentally, and I just had to get through that. Super stoked and hopefully I can build on that," he said.
The Australia A tour of India may be more aimed at long-term planning for the 2027 test series there but Konstas's knock is unlikely to go unnoticed by selectors with the first Ashes test in Perth two months away.
Australia A captain Nathan McSweeney, who opened for the test side against India last summer before being replaced by Konstas, was out lbw for one batting at number three.
