GIANTS co-captain Phil Davis believes his side's courageous four-point win over Geelong last week will do wonders for the team's self-belief.

The GIANTS had never won a game at GMHBA Stadium before they travelled to Geelong and took out the ladder leaders in round four, and they did so without Davis' inspirational fellow co-captain Callan Ward, who went down with a serious knee injury early in the clash.

Ward will miss the rest of the season after he ruptured the ACL in his left knee against the Cats and underwent a traditional knee reconstruction on Tuesday.

Davis said the team's previous struggles at the venue, combined with losing Ward and other factors during the match, made the victory even more special.

"It's just the experience, when you go to a foreign environment where you haven't had a lot of success, you're down by three or four goals for half of the game, lose arguably your best player, and find a way to win," he said.

"That teaches you a lot about resilience and having that belief in yourself and your teammates around you.

"I think we're getting better at that every week.

"Our young players are improving, and our older players seem to be playing quite well too."

While the GIANTS had found wins hard to come by in Geelong until last week, their record at UNSW Canberra Oval, where they take on Fremantle on Saturday afternoon, is a different story.

It’s a venue that holds special significance for the GIANTS, who grabbed their first premiership points in the AFL when they beat Gold Coast in Canberra in round seven, 2012.

They lost their next seven matches in the nation's capital, but since 2015 have gone 11-1 on their second home deck.

Davis said last week's triumph was a special moment in the club's history, but they can't treat this week's opponents the Dockers any differently to the way they approached the Cats.

"We've got to be just as hungry there's no doubt about that," he said.

"Where we stand right now is a really good position, but the competition is so even at the moment.

"You look at some of the teams that are going well or not going well, and you wouldn't have picked it at the start of the season.

"We've had a lot of success in Canberra and play the ground really well, but unfortunately our previous successes don't count for much on Saturday.

"They're really well coached and will likely get Nat Fyfe back, who is one of the top-five best players in the competition."

The Dockers skipper, who missed last week's Western Derby loss to West Coast with a bout of concussion, will return to face the GIANTS and is likely to have the shadow of former teammate Matt de Boer to deal with for the afternoon.

Davis said de Boer is unfazed by the extra media he's attracted over the past month, after his successful roles in shutting down Essendon's Zach Merrett, Richmond's Dustin Martin, and Geelong pair Patrick Dangerfield and Tim Kelly in the GIANTS' three wins.

"I think the way this world works is that if you do a good job, you get attention," Davis said.

"His discipline and task orientation are outstanding and there's not too much dodgy stuff that goes on off the ball either."
