BRISBANE'S Charlie Cameron thinks there might be a chink in Collingwood's armour ahead of Sunday's game following the Magpies' recent heavy workload.

After its Anzac Day victory against Essendon, Collingwood turned around four days later to lose against Richmond.

Sunday's match against the Lions at the Gabba will be Collingwood's third in 12 days.

"Collingwood have had a good month of footy, but they've had three or four games with quick turnarounds," Cameron said on Thursday.

"It's pretty taxing, running 13 to 14k's a game and a quick turnaround.

"We'll expect them to come out firing, we've got to expect that, but hopefully we can return that with our contested ball and play our way."

The Lions are winless after six rounds and fresh off a 34-point loss to Greater Western Sydney, where they matched the Giants in most areas but moved the ball poorly forward of centre.

Cameron was speaking at Marist College in Ashgrove, where he attended boarding school for five years before heading to Western Australia and ultimately being drafted by Adelaide.

With a horde of young children around him, Cameron reflected on his time at the school, saying Australian Rules was far from his first love.

"I didn't really get into it because the school is so rugby-orientated, so I played a lot of rugby," he said.

"It's always good to come out and have fun with the kids because Queensland is a rugby state, so it's good to teach them stuff I've learnt with AFL and put a smile on their faces."
