The 45-point triumph was the first win on the road for the Giants in 28 attempts, and was also their greatest winning margin and highest ever score (125).
Cameron said it was a reward for three weeks of sustained excellence after pushing Hawthorn and Essendon right to the wire in the past fortnight.
"To win on the road is a significant moment for our footy club. We've been trying for two and a half years and to win on the road in that style was really, really good," Cameron said.
The Giants (3-9) moved from the bottom of the ladder and Cameron said with an ounce of luck they may even have had another couple of wins.
They trailed by 17 points late in the second quarter, but three quick goals before the main break gave them a one point lead at half-time.
Cameron said that was where they won the game.
He was full of praise for returning captain Phil Davis, who successfully got through his first senior game in 12 weeks after suffering a career-threatening kidney injury in round one.
Ruckman Shane Mumford was also instrumental in the victory, being the catalyst for a 52-30 clearance advantage.
Cameron said Mumford's return from a knee injury four weeks ago had had a profound effect.
"It would have been great if we had him for those four or five weeks he was off," Cameron said.
"He makes a pathway for our young mids. Since he's come back into the side you can clearly see that (Dylan) Shiel and (Adam) Treloar and (Callan) Ward and these sorts of guys, (Stephen) Coniglio, just walk a little bit taller.
"I thought he was a big part in the game tonight, he had a big say."
Cameron said after some difficult times, the players could now see the light at the end of the tunnel.
"We're still going to go up and down, we're a very, very young side, but our ups and downs are going to be few and far between," he said.
"We're starting to realise if we compete and we do the things we know we can, we'll be in games for longer.
"We're really looking forward to the back end of the year."
