If the detention is legal and the person wants to be released, s/he is commonly required to bring to the hearing a trusted person (normally a family member or close relative) who is willing to act as a “bond person” by posting bond, the amount of which varies depending on the circumstances. Generally speaking, s/he must also show that: s/he is capable and trustworthy enough to abide by all conditions of release; that s/he will report as directed by the relevant authorities; and that s/he is not a flight risk.
If the ID member decides your detention must continue, you will be given another detention review hearing in 7 days and subsequently every 30 days. If you believe the decision to not release you is wrong or unfair, you have the right to appeal that decision to the Federal Court and having it reviewed by the court. For further information in this regard, please visit the “Appeals to the Federal Court” section of our website.
The detention review hearings are subject to strict regulatory and evidentiary rules and the detained person would be well advised to obtain advice and retain the services of an experienced immigration counsel.
