The Queensland Academy are fielding boys' and girls' under-19 teams, although there's a blend of players as young as under 16.
Hawke's Bay won the Challenge Cup in 2012 and will be looking to retain it this year.
Wednesday's games start at 6pm while Thursday's game starts at 5pm, with the girls and the boys from 6.45pm.
The Bay sides boast Junior Black Sticks (under-21), NZ Under-18 Tiger Turf players and a blend of Central Districts National Hockey League, CD Under-21 and CD Under-18 players.
While Junior Black Sticks player Sam Greaney is the drawcard for the boys' team, schoolboys Dylan Thomas and Mac Wilcox see the games as a stepping stone to higher honours.
"They've be been training for almost 10 times a week, building up for the New Zealand training squad of 30 which will be trimmed to 18," Hull says of Thomas, of Hastings Boys' High School, and Wilcox, of Napier Boys' High School, who head up to Auckland on Friday to make the cut for the New Zealand Under-18 squad.
Because of Queensland's strength, the Bay academy side will include striker Martin Atkins, of Wanganui, who Hulls reckons is on the fringe of Black Sticks men's call-up.
"The criterion is we have to pick players from our Central Districts region," he says, adding that Joshua Smith, of Palmerston North Boys' High School, is also in the Bay equation.
He thanks CCR's Chris and Roger Greaney for "putting their hands in their pockets" to provide the teams' kit.
