The Raiders proved the surprise-packet of 2019 and quickly became fan favourites on their way to storming into their first grand final in 25 years.

Canberra co-captain Jarrod Croker backed the Green Machine to improve in 2020 as they transform from the hunters to the hunted.

"We had a good season but at the end of the day we didn't win the comp and that's our goal," Croker said on Tuesday.

"It's going to be a different feel for us this year.

"A lot of teams are going to be coming after us. We've got to adjust to that, be prepared for that, and I've got no doubt we will be.

"We want to go one more this year.

"But we know there's 15 other sides saying the same thing.

"We set a nice foundation last year, but now we start again."

Raiders fullback Charnze Nicoll-Klokstad transformed from fringe NRL player to a New Zealand international last season.

And he echoed Croker's sentiment, saying the team's success comes down to individual accountability.

"I don't think there's expectations on the team but we put expectations on ourselves individually," he said.

"We know as a team we got to the grand final but just getting there isn't good enough, we haven't really achieved anything.

"There has been a lot of hard work this preseason and a lot of emphasis on being accountable on what you can bring to the side.

"Playing for the Kiwis was definitely a childhood dream.

"In terms of 2020, I just want to get back to playing some good consistent footy and I know I've just got to raise the bar."

Canberra lost Jordan Rapana and Aidan Sezer from their grand final side, while signing England international George Williams and rising star Curtis Scott.
