How long are medical certificates valid for?
A Medical and Chest X-ray Certificate or an X-ray Certificate
for Temporary Entry (and associated reports) must be less
than three months old at the time you lodge your application.
However, if you are applying for a temporary entry class
visa, and you have lodged another application with us
recently, and you provided a medical certificate with
your previous application, you may not have to submit
another certificate. The medical certificate that you
previously provided must be less than two years old. If
you are a fee-paying foreign student, or enrolled in a
Doctor of Philosophy (PhD) programme, or you are the
partner or dependent child of a student enrolled in a PhD
programme, the medical certificate previously provided
must be less than three years old.
