Fee payment options (credit card / bank transfer / other)

- The published admissions and fees information does not specify accepted payment methods (for example: bank transfer, credit card, Flywire or other international payment services are not listed on the fee pages). Parents should note that the school's fee pages provide the amounts, instalment rules, deposits and refund rules but do not publish the explicit payment channels on the admissions/fees pages.

If you require any of the numeric items above in a different format (for example, a single combined total for a family with multiple charges), the figures used here are taken from the school's published FY2026 admissions and fee notes and some per‑term figures are calculated by dividing the published annual tuition by three to reflect a term payment view; the school's published materials state the instalment surcharge that applies when paying by term or monthly instalments.
