GIANTS coach Leon Cameron has admitted his side's successful start to the season has exceeded his own expectations.

The GIANTS are 6-2 after a solid 24-point win over Adelaide at Spotless Stadium, their first ever victory over the Crows.

The club's first three-game winning streak was also an historic milestone for GWS, and Cameron says he'd be lying if he said the GIANTS' achievements hadn't surprised him.

"You'd take that any day of the week, if someone said we'd be 6-2 I'd be rapt, but we acknowledge we're playing some good footy, and we're starting to believe that we can compete with most sides," Cameron said post-match.

"But we know where we're at, we know we've got a long way to go. We have friendly reminders all the time, and that was three weeks ago when the West Coast Eagles smashed us."

The GIANTS took some concern from the match though, with star forward Jeremy Cameron reported for forceful front-on contact with Crows' defender Kyle Cheney in the first quarter, but the coach isn't fearful of losing his gun goalkicker to suspension.

Cameron ran into Cheney, who was hunched over the ball inside the GWS forward 50, but replays seemed to show no contact was made with the backman's head.

"My understanding is that he clipped his shoulder, but it's very hard to comment. Obviously the head is sacrosanct in our game and it should be all the time, but Jeremy is a ball player, that's one thing I'll say," Cameron said.

"He likes to attack the footy and if someone has the footy he'll attack the man." 

The GIANTS had to work hard to shake off the determined Crows, who fought back from an early 34-point deficit to get to within five points of the home side in the second quarter.

Adelaide also challenged GWS after half-time, but the GIANTS kicked the last five goals of the third term to blow the visitors off the park.

"They're competitors, they're starting to build a really good base in terms of resilience and being able to stay in the match," Cameron said.

"At some time throughout the game we lost control of a couple of things, whether it be stoppages, inside 50s, poor choices, or goal kicking and Adelaide pounced on that.

"This time two years ago when we did lose control, then the heads would hang. Now it's one of those traits that they're starting to build and believe."

Cameron believes the most successful run of form in the club's fourth season in the competition is a significant reward for the GIANTS' players, and fans.

"The supporters that have been through a few tough years, that’s the most pleasing thing," Cameron said. 

"Each time we come here to Spotless Stadium, or we play at StarTrack (Oval) in Canberra, you can see there's a little bit more energy, there's more orange waved around, there's some more members, some more walk-up supporters."

"Not only is the team on the field starting to play some really good footy, off the field supporters are starting to really get behind us."
