Power of Attorney — When You Need It, Types, and How to Set It Up

The short answer: A power of attorney (POA) lets someone else make legally binding decisions on your behalf. In Australia, the critical distinction is enduring versus non-enduring: a standard POA lapses if you lose capacity; an enduring POA continues — which is exactly why it's the one you need for aged care, dementia planning, or extended overseas travel. You must have mental capacity to grant one — it cannot be created after capacity is lost.

Types of power of attorney — and which one applies

The real issue
Most people delay setting up an enduring POA until it's needed — and by then, it may be too late. If someone loses mental capacity without an enduring POA in place, their family must apply to the tribunal for guardianship — a slow, costly, and emotionally difficult process that a $300 document could have avoided entirely. The time to set up an enduring POA is now, while the person clearly has capacity.
TypeWhat it coversWhen it appliesLapses when
General POAFinancial and legal decisions onlySpecific purpose, limited time — e.g. selling property while overseasDonor loses mental capacity OR specified end date
Enduring POA (financial)Financial and legal decisions — bank accounts, property, investmentsContinues even if donor loses capacity — used for long-term planningDonor's death, or revocation while still has capacity
Enduring guardianship / personal / medical POAPersonal and health decisions — medical treatment, accommodation, lifestyle choicesOnly activates when donor loses capacity to make those decisionsDonor's death
A standard POA does NOT cover healthcare decisions — you need a separate enduring guardianship / medical treatment decision-maker document for those. The two documents together form complete coverage for financial AND personal/health decisions.

Choosing an attorney

Who you can appoint — and what to consider

Your attorney (the person you appoint — not a lawyer) has significant power over your affairs. The choice matters more than the paperwork.

ConsiderationWhat it means
Who can be appointedAny adult with mental capacity who is not a paid carer or healthcare provider for the donor (in most states). Can be a family member, trusted friend, or professional (accountant, solicitor).
Multiple attorneysYou can appoint two or more attorneys. They can act "jointly" (must agree on everything) or "severally" (each can act independently). Jointly is safer; severally is more practical for day-to-day matters.
Successor attorneyAppoint a backup who takes over if your primary attorney cannot act (death, incapacity, resignation). Without a successor, you may need tribunal intervention if the primary attorney is unavailable.
Trustworthiness vs availabilityThe most trusted person and the most practically available person are not always the same. Consider both — an interstate sibling may be deeply trusted but unable to attend to daily banking needs.
A professional trustee company (e.g. State Trustees, Public Trustee) can be appointed as your attorney if you have no suitable person. They charge a fee but provide independent oversight and avoid family conflict. Contact your state's public trustee for information.

Safeguards

Limits on what an attorney can do — and what to do if they misuse their power

RestrictionDetail
Must act in the donor's best interestsAn attorney cannot use their power for their own benefit — they must act in the donor's best interests at all times. This includes not gifting the donor's assets to themselves or others without specific authorisation in the document.
Cannot make a willAn attorney cannot make, alter, or revoke a will on behalf of the donor.
Cannot voteAn attorney cannot vote on behalf of the donor.
Financial recordsAttorneys managing finances should keep detailed records of all transactions. The donor (if still capable), family members, or the Public Trustee can request an account of how the power has been exercised.
If you suspect an attorney is misusing their power — e.g. using the donor's funds for their own benefit, making decisions against the donor's interests — contact your state's Civil and Administrative Tribunal or the Public Trustee immediately. Each state has a guardianship tribunal that can review and revoke powers of attorney and appoint an independent administrator. This is elder financial abuse and is taken seriously.
