A bloke was red carded earlier this year in Canberra lower grade footy. Judiciary determined that a 58 match (IIRC) ban was suitable for the offence. 58 matches turns out to be effectively a 5 year ban.
Sydney Juniors have their U13's and above that are red carded for a mid range or high range offence attend Judiciary to account for their actions. Low range offence is an automatic 1 week suspension. In the younger age groups (U10-U12), the competition manager may decide to refer the offender to judiciary, but there is an automatic suspension of 1 week for the first offence.
Sydney Schools are not as formal from what I can gather, but there is usually a mandatory 1 week stand down for a Red Card imposed by the individual schools Master in Charge of Sport (or equivalent title). Longer sentences are imposed at the discretion of the MIC Sport depending on the nature of the "offence".
The CAS rugby website tells us that the CAS "Judiciary" is to all intents and purposes left up to the Headmasters of the naughty boys to determine punishment. (

"In the event of a player, or athlete being sent-off during a CAS fixture, it is the responsibility of that boy’s Headmaster at his discretion to determine the penalty. It is generally understood among Headmasters, however, that the boy will serve at least one week’s suspension from participating in the CAS competition."
Similar for ISA Schools
"Coaches must notify their Sports Convenor if any student from a team is sent off. The student(s) must be supervised by a school official after being dismissed from the field, and disciplined subsequently according to the custom and practice of the member school. It is the general rule that students will be suspended for at least one game or similar penalty as outlined by the rules for individual sports."

In most rugby, bans carry forward to the next season. So if the judiciary (not sure who has jurisdiction, but there will probably be one appointed) determine that he deserves a 3 match suspension, then the first two of Colts games are on the sidelines (assuming that the "Test" is game 1). If the lad is in an ACT Summer Colts 7's programme (if such a beast exists), then one assumes that the ban could be served on two rounds of that competition, freeing him up to play Colts trials next season.
What else would he be suspended from? All rugby of any nature, that is conducted under ARU or their affiliates sanction until the suspension is completed. IIRC, I think that there is some agreement between the various peak sporting bodies that bans in one sport apply to all sports in Australia.
He is a young kid who is probably feeling lower than a robbers dog at the moment, but he still needs to realise that there are consequences to his actions. The ignominy of being sent off in such a high profile and televised game, as well as any contrition and remorse he has, along with previous discipline record will be considered as mitigating factors by the judiciary when determining what sanction to apply to the lad if they find that he is guilty of the alleged charges. Those factors should not be considered as determining whether he is guilty or innocent of the alleged offence.
