Champness put in his best performance of the season in Newcastle Jets' 6-1 thumping of Brisbane Roar, however a late-season surge hasn't been enough to secure finals football.

It leaves Champness, finally coming back from a persistent series of injuries this campaign, on the verge of his best-form with only a match to play.

But the flashy winger-cum-rapper insists it's simply a learning experience.

"It's something you gotta walk away from," the 21-year-old said. "It happens, I'm playing football, there are injuries, you have to bounce back.

"That's what I'm looking to do, every day, is just improve. It's one of those things that you just gotta deal with. Now it's all about looking forward and finishing the season on a high note.

"Against Brisbane was a good feeling, a good result for the team. We were able to get back to our goalscoring ways and get the result which was positive.

"It feels good on a personal level to get my conditioning up and get on the path. The instruction before the game was to pull the trigger and be more aware of those opportunities to do so. 

"I felt like we're able to build up to controlling the midfield and then move into attack well. That's what we're looking to do: finish the season on a high and really perform for the fans."

While it's a positive end to the season for Champness personally, it's been a dismal campaign for Newcastle failing to make the top six after narrowly losing the Grand Final last year.

Despite such a short turnaround in success, Ernie Merrick is already planning a rebuild over the offseason with a focus on the Jets' talented youth products, with Champness set to form a key role alongside fellow Olyroos Ivan Vujica and Johnny Koutroumbis.

"It's kind of snuck up," he said.

"It's disappointing for us that this is our last game this season. But again, we're looking to give a performance that the fans deserve who've stuck with us all season."
