That is easy to find with a simple google search.
Perhaps you can point out the paragraphs that say this act supersedes the health act that allows the gov to declare a pandemic and exercise all the provisions of that act (which they haven't anywhere near used all of yet and been rather judicious in its application) . Given this act covers mainly sex, age, race & disability discrimination, not sure where your passport expiry date fits into the scope.
As you are so certain, perhaps share with members a copy (or contents of the legal argument) of the complaint it seems you may be lodging to demand your rights under this act.
Just in case you didn't get around to reading it, I'll include two sentences in the document you referenced
"This Act is not intended to exclude or limit the operation of a law of a State or Territory that is capable of operating concurrently with this Act."
"Nothing in this Act renders the Crown in right of the Commonwealth or of a State liable to be prosecuted for an offence."
