Have found potential aupair and she is from Philippines. What is best visa to apply for ?

Dear Jay,

as there's no working holiday / work and holiday visa for an au pair coming from the Philippines, she can basically only apply for a student visa - for which of course she needs to enroll in a suitable course (can be found via http://cricos.education.gov.au/)

For all details see https://connectaupair.world/ci/australia/rules/ (choose the "Student" program).

Hope this helps!

Best regards,
Maria from the cAP team
