Some adults are elligible for free entry depending on the number of students coming to the Zoo.

The ratio is:

One free entry ratio of one adult per ten primary and secondary students, and one adult per five pre-primary students.

This allowance only applies to bookings made through the Zoo's education centre. An adult is defined as a teacher, parent or carer over 18 years of age.

Otherwise adults will need to pay regular Zoo entry fees.
