Stan beat 17-year-old ‘rock chick’ Hayley Warner in the final, which was held before a record crowd at the Sydney Opera House on Sunday night.
Deputy principal at Byron Bay High School Ian Davies said he hoped Stan would return to the school soon to do a performance.
“It’s all very exciting and we have a big congratulatory sign to Stan at the front of the school,” he said.
Stan is the seventh winner of the top-rating competition.
He now looks likely to follow in the footsteps of previous winners Wes Carr and Guy Sebastian.
Holding back tears after being announced the winner, Stan thanked God and his family as a group of fans performed the Maori Haka in his honour.
“I just want to thank my family for coming and supporting me, my family they came from New Zealand,” the soul singer told the crowd on Sunday night.
The Walker family moved to Byron Bay from New Zealand in 2005.
They relocated to Coolangatta in 2007.
Another former Byron Bay High School student, Katie McMahon, also played a part in Sunday night’s Idol final.
Katie was a back-up dancer for singer and Idol co-presenter Ricki-Lee Coulter.
