Education Act 2016

If the principal of a State school is satisfied that –

a school student has behaved in an unacceptable manner, within the meaning of the Secretary's instructions, or is so behaving; and the behaviour posed or poses a risk to the health or safety of another school student, a teacher or another person at the school; and that risk may be removed only by the immediate removal of the school student from the school –

the principal may suspend immediately the school student, full-time, for a period of 2 weeks or less, as the principal considers appropriate.
