Supervision of students in Madame Tussauds Sydney is wholly the responsibility of the teachers/carers.
Supervisors are allowed free entry on the following ratios:
1:3 for pre-school students, 1:6 for K-2 students, 1:8 for Yr 3-12 students, 1:1 for disabled students
It should be remembered that the Madame Tussauds Sydney is a busy public building and students need direct supervision at all times, including in the toilets.
