If you are applying for your visa in Adelaide, Hobart, or one of the three biometrics centres in New Zealand, then you will be required to take your biometrics and your supporting documents to the post office and post your own documents to the visa application centre in Sydney or Auckland.
You will also have to include a registered post self-addressed return envelope so that your documents can be returned to you.
You must post these within 5 days of attending your biometrics appointment.
Please add in an extra 5-7 working days and factor in the extra costs for using registered posts when applying from these biometrics centres.
