Please have a look at page 13 and 14 of the pdf, highlighted for your convenience.
I have emailed only one Minister to date, and their office sent this hansard pdf.
Missing the wording of their Oaths or Affirmations.
Senate_2022_07_26_Official (pdf) Hansard
This is what was affirmed by what is being falsely called the Prime minister (not in the Hansard, recovered from another source):
“I, Anthony Norman Albanese do solemnly and sincerely affirm and declare that I will well and truly serve the Commonwealth of Australia, her land and her people in the office of Prime Minister,”
Commonwealth of Australia Constitution Act 1900
42 Oath or affirmation of allegiance.
Every senator and every member of the House of Representatives shall before taking his seat make and subscribe before the Governor-General, or some person authorised by him, an oath or affirmation of allegiance in the form set forth in the schedule to this Constitution.
Oath
I, A.B., do swear that I will be faithful and bear true allegiance to Her Majesty Queen Victoria, Her heirs and successors according to law. So, Help Me God!
Affirmation
I, A.B., do solemnly and sincerely affirm and declare that I will be faithful and bear true allegiance to Her Majesty Queen Victoria, Her heirs and successors according to law. 39 NOTE – The name of the King or Queen of the United Kingdom of Great Britain and Ireland for the time being is to be substituted from time to time.
In April 1993, when, as the result of a by-election, Michael Lavarch was sworn in as Attorney- General, Prime Minister Paul Keating changed the oath and affirmation of office:
Ministers no longer promised to serve the Queen but to serve the Commonwealth of Australia. The oath of allegiance was dropped altogether as part of the swearing-in ceremony … on the grounds that it was sworn before taking a seat in the Parliament, as required by the Constitution, and that its repetition before taking ministerial office was superfluous.[68]
However, that is NOT according to s42 of the Constitution, and Paul Keating can not change the Constitution or create a rule in contradiction to the Constitution, only The People can change the Constitution via a Referendum.
Annexure 3 – the Oath
1. Letter from Australian Parliament House confirming obligatory nature of the Oath and Affirmation to be sworn and signed by all Parliamentary members.
Annexure 3 (pdf) 2 page letter 10.6.1999 by Robyn Webber, Director, Chamber Research Office, Parliament House, Canberra, one of 35 Annexures published in the book “Australia – the Concealed Colony”.
“The wording of the oath or affirmation is set out in the schedule to the Constitution, as
follows:
OATH
I, A.B., do swear that I will be faithful and bear true allegiance to Her Majesty Queen Victoria,
Her heirs and successors according to law. SO HELP ME GOD!
AFFIRMATION
I, A.B., do solemnly and sincerely affirm and declare that I will be faithful and bear true allegiance to Her Majesty Queen Victoria, Her heirs and successors according to law.
(NOTE – The name of the King or Queen of the United Kingdom of Great Britain and Ireland for the time being is to be substituted from time to time.)
There is no provision for any deviation from this constitutional requirement. No Member may take part in proceedings of the House until sworn in.
The standing orders of the House state in relation to a new Parliament that Members shall ‘be sworn, or make affirmation, as prescribed by the Constitution’.“
