Requiring a person to state their name and address or to produce identification is an invasion of the person's privacy.
Therefore, before any exercise of such powers under legislation occur, the person exercising that power generally must state their name and produce their authorisation to do so. A member of the police force who is in uniform is exempt from the requirement to produce the authorisation but must still give their name and station if requested.
I note that a testing officer appointed by CASA to enforce AoD testing may require the production of identification which may be an ASIC or a passport.
