Srikanth defeated reigning Olympic champion Chen Long of China 22-20, 21-16 to win the men's singles title in Sydney.
The Australian Open Superseries saw a change in fortune for the Indian after he had lost five times in a row earlier to Long.
The 24-year-old player won his second Superseries title in a matter of one week after a victory in the Indonesian Open Superseries Premier.

"Heartiest congratulations to @srikidambi on winning 2nd successive superseries title. Proud of you champion! #AustralianSS," Tendulkar wrote on his twitter account.
Other cricket stars also praised the shuttler with Sehwag -- usually extremely vocal on social media -- praising the Guntur player for winning the fourth Superseries title of his career.
