Roos' Macmillan says competition for line-up is tight for NAB Challenge in Ballarat

NORTH Melbourne defender Jamie Macmillan says competition it tight for spots in next week's NAB Challenge match at Eureka Stadium.

The Kangaroos' roster has been training near full-strength leading into their first pre-season bout.

Macmillan said a long, intense training period had players hungry to get back in action and keen to return to Ballarat.

"We've had a pretty good pre-season with training numbers in the mid-to-high 30s and everyone's competing for a spot - unfortunately 24 spots does not go into 36 or so very well," Macmillan said.

Macmillan said it was important to take a short break from pre-season to meet and work with school children, footballers and community groups in the club's adopted home-away-from-home.

Players arrived in Ballarat this morning - first stop an official welcome at the town hall - for their two-day AFL community camp.
