New South Wales applies the Powers of Attorney Act 2003 (NSW) and its prescribed form. A general power of attorney here can be witnessed by any adult and does not require the prescribed witness certificate that an enduring power demands under section 19, where the witness must be a legal practitioner, a Local Court registrar, or a licensed conveyancer. If your attorney will sell, mortgage, or otherwise deal with your real estate, the power must be registered with NSW Land Registry Services before it can be used for that purpose. The Act also sets out, in section 5, exactly when the office of attorney becomes vacant, including bankruptcy or loss of capacity.
Victoria uses the Powers of Attorney Act 2014 (Vic) and is unusually clear in its terminology, calling this document a general non-enduring power of attorney and stating expressly that it covers financial matters only and cannot be used for personal or lifestyle decisions. The Office of the Public Advocate confirms it is designed for limited periods, such as running a business while overseas, and stops the moment the principal loses capacity. Certified copies must follow the page by page certification rule in the Act.
Queensland is governed by the Powers of Attorney Act 1998 (Qld), read together with the Guardianship and Administration Act 2000 (Qld). Queensland draws the same line as the other states: a general power is used while you still have capacity, and an enduring power is the instrument that survives its loss. Principals dealing with land should check registration requirements with Titles Queensland before the attorney acts on any property matter.
South Australia operates under the Powers of Attorney and Agency Act 1984 (SA), where the document is styled a deed and the parties are the donor and the donee. A general power in SA covers financial matters only and becomes invalid the instant the donor loses mental capacity, at which point court intervention or a SACAT administration order may be needed if no enduring appointment exists. As in every state, the power ends automatically on the donor's death.
