Power of Attorney and Enduring Guardian Australia: Who Decides If You Can't?

Why Power of Attorney matters

Power of Attorney (POA) is a legal document appointing someone you trust (your attorney or agent) to make decisions on your behalf when you cannot — due to illness, accident, or loss of mental capacity.

The critical point: if you lose capacity without a valid POA in place, your family cannot automatically step in. Banks will freeze accounts. Medical decisions may need to go to a tribunal. The assets and care decisions you most wanted controlled by specific trusted people may instead be handled by strangers following bureaucratic processes.

This affects people of all ages — not just the elderly. A serious accident, a stroke, or a sudden illness can happen at any time.

Two distinct types of POA

1. Enduring Power of Attorney (financial)

Authorises your attorney to manage:

Bank accounts and investments.
Buying and selling property.
Paying bills and taxes.
Running a business (if explicitly included).

“Enduring” means the authority continues even if you lose mental capacity — the key distinction from a general POA, which typically ends when you lose capacity (precisely when you need it most).

2. Medical/personal POA (guardianship)

Authorises your decision-maker to:

Consent to (or refuse) medical treatment on your behalf.
Decide where you live or receive care.
Make lifestyle decisions.

This does not include financial decisions — you need both types to cover all situations.

Note on naming conventions by state:

State	Financial POA	Medical/Personal POA
New South Wales	Enduring Power of Attorney	Enduring Guardianship
Victoria	Enduring Power of Attorney	Medical Treatment Decision Maker
Queensland	Enduring Power of Attorney	Advance Health Directive / Health Attorney
South Australia	Enduring Power of Attorney	Enduring Power of Guardianship
Western Australia	Enduring Power of Attorney	Enduring Power of Guardianship

The names differ but the concepts are equivalent across states.

When to set up a POA

You can only create a valid POA while you have mental capacity. If you wait until after an illness or accident has affected your capacity, it is too late to create one — a court or tribunal must step in instead.

POA is not just for older people:

Any adult can have an accident or sudden illness.
People travelling internationally for extended periods should have POA in place covering Australian assets.
Young adults (18+) with property or investments benefit from having POA regardless of age.

Set up your POA alongside your will — they complement each other. Your will covers what happens after you die; your POA covers what happens while you’re alive but unable to decide.

Choosing your attorney

Your attorney has significant power over your finances or health. Choose carefully:

Someone you trust completely — typically a spouse, adult child, or long-term close friend.
Someone who is themselves mentally capable and an adult.
Someone organised and able to deal with banks, government agencies, and professionals.
For financial POA: someone with reasonable financial literacy.
Avoid conflict of interest: don’t appoint someone who is paid to provide you care (e.g., a home carer or nursing home operator).

You can appoint multiple attorneys who act jointly (both must agree) or severally (either can act independently). Consider naming a backup attorney in case your first choice becomes unavailable.

When does the POA take effect?

You choose:

Immediately — the attorney can act as soon as the document is signed (useful if you want help managing finances before any capacity concerns).
On a triggering condition — typically “if I lose mental capacity,” confirmed by a medical practitioner’s certificate.

For older adults, the “on incapacity” trigger is common, ensuring the attorney can only act when genuinely needed.

What happens without a POA?

Your family will need to apply to the relevant tribunal for appointment as your legal guardian and/or financial administrator:

Victoria: VCAT (Victorian Civil and Administrative Tribunal)
NSW: NCAT (NSW Civil and Administrative Tribunal)
Queensland: QCAT (Queensland Civil and Administrative Tribunal)
Other states have equivalent bodies.

This process typically takes several months, involves interviews and investigations, and the tribunal appoints whom it considers appropriate — which may not be who you would have chosen. During this time, financial accounts may be frozen and medical decisions may be delayed or made without your family’s input.

How to create a valid POA

Each Australian state has its own official form and witnessing requirements:

Download the official form for your state from the relevant government website.
Complete the form, specifying the scope of authority you are granting.
Sign in the presence of qualified witnesses — requirements vary by state (may include a solicitor, Justice of the Peace, registered medical practitioner, or other authorised person).
Your witnesses confirm that you appeared to understand what you were signing and were not under pressure.
Distribute copies — keep the original in a safe place and give your attorney a certified copy.

You do not generally need to register a POA with the government, but you should keep it accessible so your attorney can produce it when needed.

A solicitor can prepare both financial and personal/medical POA documents for you — typical cost is $300–$600 for both.
