Enduring Power of Attorney for Dementia in Australia: State-by-State Guide

Without an Enduring Power of Attorney in place, a dementia diagnosis can strip your entire family of the ability to manage your parent's affairs. Banks freeze accounts. Hospitals refuse to discuss treatment options. Aged care providers will not accept your signature on accommodation agreements. This is not a hypothetical — it is what happens when capacity is lost before legal documents are executed.

When Is It Too Late?

An Enduring Power of Attorney (EPOA) must be signed while your parent has cognitive capacity — they must understand the nature and effect of the document at the time of signing. A dementia diagnosis alone does not mean capacity is lost. Many people with early-to-moderate dementia retain sufficient capacity to execute legal documents, but this window closes as the condition progresses.

If there is any doubt about capacity, have the signing witnessed by a solicitor who conducts a formal capacity assessment and documents it in their file notes. This protects the document against future legal challenges from other family members or institutions.

Once capacity is fully lost, you cannot create an EPOA. The only option is applying to a state tribunal for guardianship and administration orders — a process that costs thousands in legal fees, takes weeks to months, and places decision-making under ongoing judicial oversight.

What You Need: State-by-State

Australian power of attorney law is governed by state and territory legislation, not federal law. The documents required differ significantly.

NSW — Two Separate Documents Required

• Enduring Power of Attorney (Powers of Attorney Act 2003) — covers financial decisions only: banking, property, investments, superannuation
• Appointment of Enduring Guardian — covers personal, medical, and lifestyle decisions including aged care placement and treatment consent

NSW requires two separate documents. An EPOA alone does not grant authority over medical decisions or aged care placement.

Tribunal: NSW Civil and Administrative Tribunal (NCAT)

Victoria — Combined EPOA + Separate Medical Decision Maker

• Enduring Power of Attorney (Powers of Attorney Act 2014) — covers both financial and personal decisions in a single document
• Medical Treatment Decision Maker — a separate appointment for medical treatment consent

Tribunal: Victorian Civil and Administrative Tribunal (VCAT)

Queensland — Single Combined Document

• Enduring Power of Attorney — covers financial, personal, and health decisions in one document. Queensland's framework explicitly upholds statutory human rights principles.

Tribunal: Queensland Civil and Administrative Tribunal (QCAT)

Western Australia — Two Separate Documents

• Enduring Power of Attorney (Guardianship and Administration Act 1990) — financial decisions
• Appointment of Enduring Guardian — personal and medical decisions

Tribunal: State Administrative Tribunal (SAT)

South Australia — EPOA + Advance Care Directive

• Enduring Power of Attorney — financial and property management
• Advance Care Directive — replaced the old enduring guardianship framework for personal, medical, and end-of-life decisions

Tribunal: South Australian Civil and Administrative Tribunal (SACAT)

Tasmania — Registration Is Mandatory

• Enduring Power of Attorney — financial decisions
• Appointment of Enduring Guardian — personal and medical decisions
• Both documents must be formally registered with the Tasmanian Land Titles Office to carry legal validity. Tasmania is the only state with this requirement.

Tribunal: Tasmanian Civil and Administrative Tribunal (TASCAT)

ACT — Combined Document

• Enduring Power of Attorney — covers financial, personal, and healthcare decisions (including medical research) in a single document

Tribunal: ACT Civil and Administrative Tribunal (ACAT)

Northern Territory — Advance Personal Plan

• Advance Personal Plan — a combined document covering financial and personal decisions. Replaces older EPA formats.

Tribunal: Northern Territory Civil and Administrative Tribunal (NTCAT)

What an EPOA Covers in Aged Care

With a valid EPOA, the appointed attorney can:

• Access bank accounts and manage financial transactions
• Sell or retain the family home
• Sign aged care accommodation agreements (including RAD/DAP)
• Consent to care plans and services
• Submit the SA457 means-test form to Services Australia

With a valid enduring guardianship (or equivalent personal decision-making instrument):

• Consent to medical treatment
• Make decisions about residential care placement
• Authorise restrictive practices if required (as the Restrictive Practices Substitute Decision Maker)

Cost of Getting It Done

Expect to pay $350–$500 for a single document, or $700–$900 for a bundled estate planning pack (EPOA + guardianship + will review) from an elder-law solicitor. This is a fraction of the cost of a tribunal application if you miss the window.

The Australian Dementia Care Support Toolkit includes a state-by-state EPOA comparison chart, capacity assessment preparation guide, and templates for organising the documents you need before meeting with a solicitor.
