Cooper Cronk says the milestone of his skipper, Cameron Smith is a 'magical achievement'.

The halfback, who began his career with Smith at Storm feeder team Brisbane Norths explained the milestone was more than the number.

"It's probably the way he has gone about it, his consistency, the level," Cronk said.

"He's a special footballer and it will be a special night for all involved."
