GREATER Western Sydney could be boosted by the return of star forward Jeremy Cameron when they take on West Coast on Saturday.

Cameron has missed four of the past five games with a hamstring issue, but trained strongly at Spotless Stadium on Wednesday to press his case for a recall against the Eagles.

The Giants are unlikely to take a risk with their leading goalkicker, who didn't complete the whole session, but moved well when he was on the track.

While some doubt still remains over Cameron's availability for the club's last home game of the regular season, fellow forward Devon Smith (knee) is a likely inclusion, and ruckman Shane Mumford (suspension) is certain to play after both missed last week's win over the Western Bulldogs.

Key defender Adam Tomlinson was a surprising late withdrawal against the Dogs for team balance, but could be recalled to counter the visitors' tall forward options.

Coleman Medal leader Josh Kennedy and Jack Darling kicked eight goals between them last week, while ruckmen Drew Petrie and Nathan Vardy have both spent time inside 50 for the Eagles this season.

GWS wingman Tom Scully said it was encouraging to see the club's long injury list shrinking this close to the finals.

"It's great to see those guys back out on the track, we've missed them the last couple of weeks," he said.

"Shane is a real barometer for us when he's playing his best football, he's aggressive at the man and at the ball and we love the way he plays.  

"It's obviously going to be a tough decision for the coaches, but having Jeremy, Devon and Shane putting their hands up for selection is only going to be a good thing for our side."

The Giants won just one of their first five games after the bye but have recovered from that flat period to beat Fremantle, Melbourne and the Bulldogs over the past three weeks. 

In that time Leon Cameron's men have averaged 100 points per game, and while from the outside it looks like the return of the Giants' free-flowing style has been the catalyst for the form reversal, Scully said the real reason was the team's attitude towards its team defence.

"We were far too inconsistent during that period and allowing easy scores, which is something we don't want to be renowned for," he said.

"We've certainly rectified that I think and our defensive mindset has been at the forefront. 

"It's definitely bred confidence in the group that if we can bring that defensive pressure, our offensive style can work off the back of that."

The clash will feature two of the League's most powerful runners on opposite sides of the ground, with left footers Scully and Andrew Gaff extremely influential for their respective sides. 

Gaff leads the competition in uncontested possessions and averages over 30 disposals per game, while Scully is unmatched in the AFL for his two-way running ability, and has had another consistent year for GWS. 

"Andrew is a fantastic player, an All Australian, and I admire the way he's goes about it," Scully said.

"In my opinion he's one of the best wingers in the competition so our boys will have to try and nullify him this weekend. 

"There's no doubt they've got a number of guys going through that midfield that are top-end talent."
