Power of Attorney vs a Will: What Is the Difference?

People often lump them together, but a will and a power of attorney do very different jobs, and at different times. Understanding the difference is one of the simplest ways to spot a gap in your own planning. A power of attorney is only valid during your lifetime, and after death your will comes into effect, so one document hands over to the other on the day someone dies.

A will is for after you die

Your will only takes effect once you have passed away. It says who should receive what, names an executor to carry it out, and can record your wishes for things like guardianship of children. Until then, it does nothing at all.

A power of attorney is for while you are alive

A power of attorney is the opposite: it operates while you are alive, in situations where you cannot make or communicate decisions yourself, such as a serious illness or accident. It lets someone you trust step in and act on your behalf. There are generally different kinds, often covering financial and property matters separately from personal, lifestyle or medical decisions, and the names and rules for these differ between states and territories.

Does a power of attorney end when someone dies?

Yes, at the moment of death. NSW Trustee and Guardian says a general power of attorney becomes invalid when you die or lose capacity, and that an enduring power of attorney also becomes invalid when you die.

So the attorney's authority stops and the executor named in the will takes over. That is what catches families out. The daughter who has been paying the bills for two years has no authority the morning after the funeral, and the bank will tell her so.

What are the three kinds of power of attorney in Australia?

One phrase covers several documents, and the names change the moment you cross a state border. Moneysmart, ASIC's consumer site, sorts them into a general power of attorney, an enduring power of attorney, and enduring guardianship, sometimes called a medical power of attorney.

General. Someone makes financial and legal decisions for a set time, the sort of thing people arrange before going overseas, and it ends if you lose the ability to make decisions. Victoria adds that its version covers money only. (Sources: moneysmart.gov.au and publicadvocate.vic.gov.au, checked 19 Sep 2026)

Enduring. The same job, except it keeps working if you lose the ability to make decisions. This is the one most people mean. (Source: moneysmart.gov.au, checked 19 Sep 2026)

The health and lifestyle one, whose name depends on where you live. In New South Wales an attorney can only make financial and legal decisions. Accommodation, healthcare, lifestyle and medical decisions need a separate appointment of enduring guardian. (Sources: nsw.gov.au and nsw.gov.au, checked 19 Sep 2026) In Victoria an enduring power of attorney can cover personal matters or financial matters or both, but your attorney cannot make medical treatment decisions unless they are also your medical treatment decision maker, a separate appointment. (Sources: publicadvocate.vic.gov.au and legalaid.vic.gov.au, checked 19 Sep 2026) Queensland folds more into the one document, where personal matters expressly include health care. (Source: qld.gov.au, checked 19 Sep 2026)

So the useful question is not whether you have a power of attorney. It is whether the document you signed reaches health and lifestyle in the state you live in now.

Why the gap matters

Here is the part many people miss. If you have a will but no power of attorney, and something happens that leaves you unable to manage your own affairs, your will cannot help, because you have not died. Without the right authority in place, your family may have to apply to a tribunal or court before they can act for you, at the very moment speed and calm would matter most.

Can an attorney change a will?

No. Queensland's Office of the Public Guardian lists what an attorney cannot do, and the first item is make or change your will. The list also rules out voting on your behalf, making decisions about your children, acting illegally or unethically, and overriding your wishes unless following them would be impossible or cause harm. (Source: publicguardian.qld.gov.au, checked 19 Sep 2026) Only you can change your will, and only while you have the capacity to do so.

What an attorney can do with your money while you are alive is much wider. In New South Wales that runs to operating bank accounts, paying bills, signing binding documents, buying and selling real estate, managing investments and collecting rent. (Source: nsw.gov.au, checked 19 Sep 2026)

The limits are written down, though. Queensland requires an attorney to keep accurate records of every transaction, to keep their own property and finances separate from yours, and to stay out of conflict transactions, meaning one where their duty to you collides with their own interest. Buying your house off you cheaply is the example given. Gifts are allowed only where you would have made the gift yourself and the amount is reasonable, and your money cannot buy gifts for the attorney or their family. (Source: publicguardian.qld.gov.au, checked 19 Sep 2026) The State Library of NSW legal answers service points at the statute: the Powers of Attorney Act 2003 confirms an attorney cannot use the principal's assets for any purpose other than the principal's benefit, unless the document expressly authorises it.

What can you check this week?

None of this is advice about your situation. It is what you can look at at the kitchen table, without an appointment and without a fee.

1. Find the documents and read the front page. A general power of attorney and an enduring one look alike and behave very differently once capacity is lost.
2. Check whether health and lifestyle are covered at all. New South Wales needs a separate enduring guardian, Victoria a medical treatment decision maker, and Queensland can hold both sides in the one document. (Sources: nsw.gov.au, legalaid.vic.gov.au and qld.gov.au, checked 19 Sep 2026)
3. Check whether your attorney and your executor are the same person. If not, both should know the handover happens the day you die.
4. Look at what the will does not reach. Superannuation is the big one, because the fund usually decides where it goes. What happens to your super when you die covers it.
5. Write down where the originals are kept. NSW Trustee and Guardian asks you to store the original safely and tell your attorney where to find it. (Source: nsw.gov.au, checked 19 Sep 2026) That is the whole job of The Estate Organiser: one place for the documents, accounts and wishes, so nobody has to hunt.

What to do about it

Putting a power of attorney in place is a legal task, and the right arrangement depends on your situation and your state, so it is one to set up with a solicitor or your state's relevant office. It is often quicker and simpler than people expect.

And once these documents exist, the people who may one day rely on them need to know they exist and where to find them. That is where The Estate Organiser helps: a single place to record your will, any powers of attorney, and everything else your family would otherwise have to hunt for.
