National Consumer Credit Protection Act 2009

Evidence of information given, or evidence of production of documents, by a natural person is not admissible in criminal proceedings against the natural person if:

the natural person previously gave the information or produced the documents in proceedings for a declaration of contravention, a pecuniary penalty order or a relinquishment order against the natural person for a contravention of a civil penalty provision (whether or not the declaration or order was made); and

the conduct alleged to constitute the offence is substantially the same as the conduct in relation to which the declaration or order was sought.

However, this does not apply to criminal proceedings in relation to the falsity of the evidence given by the natural person in the proceedings for the declaration or order.
