Betts has been in career-best form and become a favourite of fans across the country since joining the club from Carlton at the end of 2013.

He has not missed a game in the past three seasons and been Adelaide’s leading goal kicker, while twice earning All-Australian honours.

The 30-year-old also finished runner-up in Adelaide’s Club Champion last year.

“The club is in great shape and we have such a positive environment where everyone works really hard but also knows how to make it enjoyable as well,” Betts said.

“Playing finals footy is what it is all about and after experiencing that the last couple of years I know this playing group is capable of much more.

“Everyone at the club has been really good to me and I love our fans too. They have made my family and I feel so welcome from the first day I arrived.”

Betts has played 69 matches at Adelaide, bringing his career tally to 253, and kicked 479 goals.
