上面说:
Passport detailsThe passport you use should be the one you intend to use to travel to Australia if a visa is granted. This passport should be valid for at least two years.
This passport must be used to provide evidence of your identity when required as part of your application process. You and any accompanying family members on your passport will need to present this passport to the doctor when undertaking health examinations. Accompanying family members who are not on your passport will also need to provide their own passport.
You must provide certified copies, and translations where necessary, of the 'Personal Particulars' page of all your passport/s, and those of any accompanying family members. You should also include any stamps or authorisations amending passport details, such as passport validity extensions.
If you, or any family member, do not currently hold a passport, or need to renew a passport, please do so before lodging your application so the certified copies of the relevant pages can be included in your application.
