Shahril, who was captain of the Lions side and was also named Most Valuable Player of the tournament, was named Player of the Year in the men's category, while Avramovic, who has since parted ways with the side, won Coach of the Year at the inaugural awards ceremony.
Apart from the duo, LIONSXII centre-back Baihakki Khaizan and Tampines Rovers captain Mustafic Fahrudin were also recognised by being named in the Best XI, along with Shahril.
Speaking after winning the award, Shahril admitted 2012 had been a memorable year for Singaporean football as the national team won Southeast Asia's biggest international prize for a record fourth time.
"It was a great year for Singapore," he said in a statement released by the Football Association of Singapore (FAS) on Wednesday evening. "Especially so when we [won] the AFF Suzuki Cup for a record fourth time last December.
"It is a great honour for me, Bai[hakki] and Mustafic to have been named in the first XI of this region.
"We will continue to work hard, build on our success and strive to further develop and improve Singapore football."
Shahril had to see off a number of equally-outstanding candidates to win the award, given the other nominees were Thailand and Muangthong United striker Teerasil Dangda, Philippines captain Emelio Caligdong and Myanmar's rising star Kyi Lin.
Meanwhile, Avramovic pipped Thailand's Winfried Schafer, Azkals boss Michael Weiss and K. Rajagobal of Malaysia to win in his category, and he admitted it was a perfect way to end off his nine-year spell in charge of Singapore.
"I am deeply honoured to be awarded the coach of the year with Singapore national football team," he said.
"2012 was a memorable year as Singapore achieved a record fourth AFF [ASEAN Football Federation] title. It was a great nine-year tenure with the Lions.
"I am confident that Singapore football will continue to progress in the years ahead."
Singapore were also winners in the Referee of the Year (Men's) and Assistant Referee of the Year (Men's) awards as Abdul Malik and Tang Yew Mun were crowned winners in those respective categories, while the Lions were crowned National Team of the Year (Men's).
