After exploring interest from Victorian clubs including Melbourne and St Kilda in recent days, Amon has recommitted to the Power until the end of 2022.
Just 12 months after attempting - and failing - to break a contract and return to Victoria, the 24-year-old received significant interest from his home state this time around after a career-best season.
Amon has found himself settled in South Australia this season and played a career-high 17 matches, averaging 20 disposals.
His decision to stay comes as teammate Sam Gray explores his options over the next fortnight after recovering from minor shoulder surgery.
Gray, who kicked 20 goals from as many matches this year, has received interest from multiple clubs including Carlton and Western Bulldogs (who are both seeking a small forward).
Power ruckman Paddy Ryder is poised to move to Moorabbin on a two-year contract, while Sam Powell-Pepper is likely to stay despite finding himself in and out of the best line-up late in the season.
