Just as another comment to watch out for, do not apply to have your passport renewed if you think that you will need to use it soon in a hurry, at the moment with state border closures, passports being printed in Melbourne, not many aircraft flying and hence Australia Post going into glacial mode for registered and all mail (and tracking of registered mail not being currently done) - a passport applicant has no idea when their new passport will turn up, and of course your old passport is helpfully destroyed when you submit your application.
Not a huge issue for most people at the moment, but for people who may have ill or sick relatives, and may have the need to travel overseas urgently and are considering getting an ABF exemption to travel overseas, bear this in mind before you decide to renew your passport.
