I agree that my child will be subject to the direction of the teachers conducting the excursion, and will expect him/her to obey all school rules and instructions governing safety and appropriate behaviour. In the event of an emergency, where the teacher-in-charge is unable to contact me, or it is otherwise impracticable to contact me, I authorise the teacher -in-charge to consent to my child receiving any medical or surgical attention deemed necessary by a medical practitioner. I also authorise the teacher-in-charge to administer such first-aid that he/she judges to be reasonably necessary.
