No room for injury there, I wonder if a few of the guys not picked in the 23's for the U18 side will be in reserve for the schoolboys as well.
"The process has involved regular meetings and discussions on players across the system, leading to a final selection day where we selected the top 30 U18 players in the Australia U18 squad, allowing the Australian Schools to follow and select their 23-player squad with the stipulation that these players are U18, attend school and attended the National Schoolboy Championships held in July."
