Thanks Wayne for your question about the oath or affirmation that members and senators swear. The schedule of the Australian Constitution requires senators and members of the House of Representatives affirm their allegiance to the Crown. Senators and members are required to both make and subscribe – sign – an oath or affirmation. The same oath and affirmation have been used since Federation and can only be changed by a referendum. Senators and members can decide whether they would like to swear the oath or the affirmation.
