Douglas joined the Jets mid-season after moving to Beckom and played a key role across half-back in their run towards finals.

He's been appointed assistant coach to Avis, who impressed the club in his first full season as coach (after the abandoned season of 2020 in his first year), taking the Jets to fifth spot.

"He's really had a local focus in 2021 and we hope that continues, educating and developing the players we have and having them play as a team," Jets president Simon Gaynor said.

"Josh had them enjoying their footy and we had big numbers at training.

"He's a very good coach and we're ready to try and get into finals and get a couple of positions higher up the ladder."

Avis said he's thrilled to again be leading the Jets where he is right at home and happy to see out his playing career.

He had maintained since during the season that he was happy to fit in with whatever the Jets decided was the best fit for their future.

Douglas is also happy at his newly adopted club and Gaynor said they were excited to tap into his knowledge.

"Mal brings a lot of experience with football game plans and a lot of tactics as well, so we're very excited... he's been a real good educator for our young players and helping out with their positional play," Gaynor said.

"He's very good at reading the play. And he's the type of leader you want, a good role model for the young blokes and he and Josh get along very well so it's going to be a good partnership."

The coaching line-up was confirmed at the club's presentation day on Saturday, where star midfielder Mitch Haddrill was announced best-and-fairest, his third career win (after 2016 and 2019 victories).

Haddrill was also the league player of the year (voted by coaches) and narrowly missed a third Gerald Clear Medal, finishing behind East Wagga-Kooringal's Harry Fitzsimmons.

Impressive ruckman Lachie Jones' brilliant season was recognised with a runners-up finish, just ahead of Jack Fisher.

The Jets' priority is to keep their talented list together as they aim for another tilt at a first finals appearance since 2016, after COVID-19 forced the cancellation of this year's finals (after the Jets had already been culled when the potential finals was shortened to a top four).

They hope to retain their players including keeping Stephen Coate around the club, despite rupturing his ACL at The Rock late in the season.

They played an entertaining, high scoring brand of football, finishing with the second best attack in the competition.

They scored 100 to 150 points more than the other top five sides, apart from minor premiers Marrar, and believe there's plenty of upside in their emerging footballers.

They also had strong numbers in their under 17.5s, with 25 players registered.

At a successful club function at Ariah Park on Saturday to celebrate their season, the Jets also recognised three new life members, bestowing the honour on Glen Bell, Brian Johnstone and Debbie Worland.
